  • This sinking or downward movement is due primarily to deflection of the heel region of the outsole and compression of the heel region of the midsole as they each respond to the increasing weight being transmitted through the user's heel as the step progresses and the user's heel continues to bear an increasing amount of the user's weight until it reaches a maximum.

3 [0001] This application claims the benefit of priority based on
4 Provisional Application No. 61/122,911 filed December 16, 2008.
5 /. Field of the Invention
6 [0002] The present invention relates to footwear and, in particular, to a
7 shoe with fitness benefits. The fitness benefits are imparted by a unique walking
8 action which is induced by the shoe's midsole. This midsole has multiple layers,
9 multiple densities, a longitudinal convexity, and a longitudinal concavity. The
10 induced walking action mimics the effect of walking on a sandy beach or on a
11 giving or uneven surface,

13 [0003] Shoes are designed for many purposes — from protection on the
14 job, to performance during athletic activity on the track or court, to special
15 occasions and everyday lifestyle. Shoes have also been used to promote physical !6 health and activity. Increasingly, shoes have given users fitness benefits. Many
17 shoes have attempted to provide users the benefit of improving the user's fitness by is simply walking while wearing such shoes. However, there continues to be a need
19 for such shoes that improve the user's health yet are comfortable and easy to use. 0 [0004] Walking is one of the easiest and most beneficial forms of ! exercise. When done properly and with the appropriate footwear, it strengthens the2 heart, improves cardiovascular health, increases one's stamina and improves3 posture. It also helps to strengthen one's muscles and maintain joint flexibility.
[0005] Prior art shoes have attempted to improve the user's fitness by mimicking walking barefoot. See, for example, U.S. Patent, No. 6,341,432 to Mϋller. Such shoes can include an abrupt, discrete pivot point provided by a hard inclusion. Consequently, in every step taken during normal walking while wearing such shoes, the user is forced to overcome this abrupt, discrete pivot point. This can result in significant pain and discomfort. [0006] The present invention aims to provide a way of mimicking walking on a sandy beach or on a giving or uneven surface, while not inducing any pain or discomfort from doing so. By mimicking walking on a sandy beach and/or on an uneven surface, the present invention aims to significantly increase the fitness and health benefits of everyday walking by requiring the user to exert additional effort and energy while walking and to use muscles that the user otherwise would not use if wearing ordinary footwear, again all without inducing any pain or discomfort.
SUMMARY OF THE MVENTION [0007] It is an object of the present invention to provide a shoe that mimics the effects, and imparts the fitness benefits, of walking on a sandy beach or on a giving or uneven surface without inducing any pain or discomfort from doing so. The present invention is a shoe comprising an upper, an outsole, and a midsole, each having a medial side and a lateral side. In a preferred embodiment, the midsole is affixed to the upper and the outsole is affixed to midsole. The upper, midsole, and outsole each has a frontmost point and a rearmost point substantially
opposite the frontmost point. When the shoe is being worn by a user, each frontmost point and each rearmost point is oriented with respect to one another such that each frontmost point is closer to the user's toes than each rearmost point while at the same time each rearmost point is closer to the user's heel than each frontmost point. [0008] The shoe has a front portion and a rear portion substantially opposite the front portion. When the shoe is being worn by a user, the front portion and the rear portion are oriented with respect to one another such that the front portion is closer to the user's toes than the rear portion while at the same time the rear portion is closer to the user's heel than the front portion. [0009] The shoe has a front tip that is located at the farthest forward point of the shoe when moving from the rear portion to the front portion. The shoe has a rear tip that is located at the farthest rearward point of the shoe when moving from the front portion to the rear portion. In a preferred embodiment, the front tip coincides with the frontmost point of the upper, the frontmost point of the midsole, or the frontmost point of the outsole while the rear tip coincides with the rearmost point of the upper, the rearmost point of the midsole, or the rearmost point of the outsole. In a preferred embodiment, the frontmost point of the upper, the frontmost point of the raidsole, and the frontmost point of the outsole are all located relatively close to one another while the rearmost point of the upper, the rearmost point of the midsole, and the rearmost point of the outsole are all located relatively close to one another.
1 [00010] The upper, midsole, and outsole each has a toe region. The toe
2 region includes the region that extends substantially from the medial side to the
3 lateral side at a location that begins in the vicinity of the front tip of the shoe and
4 extends from there to a location that is approximately one third of the distance
5 toward the rear tip of the shoe.
6 [0001 1] The upper, midsole, and outsole each has a heel region. The
7 heel region includes the region that extends substantially from the medial side to
8 the lateral side at a location that begins in the vicinity of the rear tip of the shoe and
9 extends from there to a location that is approximately one third of the distance w toward the front tip of the shoe. n [00012] The upper, midsole, and outsole each has a middle region. The
12 middle region includes the region that extends substantially from the medial side to
13 the lateral side at a location that extends approximately between the toe region and H the heel region.
15 [00013] In a preferred embodiment, the midsole further comprises an
16 upper layer and a lower layer, the upper layer having a first density and the lower
17 layer having a second density different from the first density. The upper layer has is a top surface and a bottom surface substantially opposite the top surface. The9 bottom surface has a single longitudinal convexity (as defined below) that occupies0 a substantial portion of the toe region or a substantial portion of the toe region and 1 the middle region, and a single longitudinal concavity (as defined below) that2 occupies a substantial portion of the heel region.
1 [00014] In a preferred embodiment, the invention includes an outsole
2 that, when no load is applied, curves continuously upward in a direction toward the
3 upper beginning at a location near the middle region of the outsole and ending at a
4 location near the rearmost point of the upper. In this preferred embodiment, the
5 upper layer and the lower layer of the midsole each extend from at least the
6 vicinity of the front tip of the shoe to at least the vicinity of the rear tip of the shoe.
7 The upper layer is made from a material having a first density sufficiently dense to s support and stabilize the user's foot. Typically, the upper layer has a density
9 between about 0.400 and about .500 grams per cubic centimeter and a durometer
10 between about 50 and about 75 on Shore A (ASTM D2240). The upper layer
11 typically has a relatively low compressibility so that it compresses a relatively low,
12 or small, amount under a given load. The lower layer, which may or may not be
13 made of the same material as the upper layer, has a second density that is different
14 from the first density and is sufficiently low in density and high in compressibility
15 so as to allow the lower layer to compress and deform a higher, or greater, amount
16 under a given weight than the upper layer would compress and deform under that π same weight. Typically, the lower layer has a density between about 0.325 and is about .419 grams per cubic centimeter and a durometer between about 15 and
19 about 38 on Shore A (ASTM D2240). The density of the lower layer is 0 sufficiently low and the compressibility of the lower layer is sufficiently high so 1 that under normal walking conditions the user's foot, first in the heel region, then2 in the middle region, and then finally in the toe region, sinks toward the ground as
the lower layer compresses and deforms due to the lower layer's relatively low density and/or high compressibility. [00015] Thus, during walking while wearing a preferred embodiment of the instant invention, when the curved heel region of the outsole strikes the ground, the heel region of the lower layer, which is less dense and more easily compressed than the upper layer, deforms to a relatively large degree compared to the upper layer. After each such initial heel region contact with the ground, the user's heel sinks or moves toward the ground more than it would sink or move in a conventional shoe. This sinking or downward movement is due primarily to deflection of the heel region of the outsole and compression of the heel region of the midsole as they each respond to the increasing weight being transmitted through the user's heel as the step progresses and the user's heel continues to bear an increasing amount of the user's weight until it reaches a maximum. The impact is akin to a heel striking a sandy beach or a giving or uneven surface. Then, as the user's weight begins to shift toward the middle region of the shoe, the shoe rolls forward in a smooth motion, without the user having to overcome any abrupt or discrete pivot points. Then the lower layer of the midsole in the middle region and then in the toe region compresses and deforms under the increasing weight of the user's foot in those regions as the step progresses. This compression and deformation allows the user's foot to sink further toward the ground than would be the case with a conventional shoe. The user then completes the step by pushing off with the forefoot ball area of the user's foot. This push-off further compresses and deforms the lower layer in the toe region.
[00016] As used herein, "longitudinal convexities" and "longitudinal concavities" mean, refer to, and are defined as, respectively, convexities and concavities that lie only in vertical, longitudinal planes that extend from any local frontmost point of the shoe to a corresponding local rearmost point of the shoe when the shoe is in its normal, upright position. As used herein, "transverse convexities" and "transverse concavities" mean, refer to, and are defined as, respectively, convexities and concavities that lie only in vertical, transverse planes that extend from any local medialmost point of the shoe to a corresponding local lateralmost point of the shoe when the shoe is in its normal, upright position. [00017] All convexities and concavities in the instant invention, both longitudinal and transverse, are all identified herein as being on, and being a part of, the bottom surface of the upper layer. Under this convention, each longitudinal convexity and each transverse convexity identified herein is, to some degree, an outward bulge of the bottom surface of the upper layer and each longitudinal concavity and each transverse concavity identified herein is, to some degree, an inward depression in the bottom surface of the upper layer. The outward bulge of each longitudinal convexity and of each transverse convexity means that the upper layer is relatively thick wherever it has a longitudinal or transverse convexity. This increased thickness of the upper layer corresponds to a decrease in thickness of the lower layer at each location where the lower layer is opposite a longitudinal convexity or a transverse convexity. Similarly, the inward depression of each longitudinal concavity and of each transverse concavity means that the upper layer is relatively thin wherever it has a longitudinal or transverse concavity. This
1 increased thinness of the upper layer corresponds to a decreased thinness, i.e., a
2 thickening, of the lower layer at each location where the lower layer is opposite a
3 longitudinal concavity or a transverse concavity.
4 [00018] Each convexity and concavity, both longitudinal and transverse,
5 has at least five primary variables that control the effect of each such convexity
6 and each such concavity. These primary variables are (1) the location where each
7 longitudinal and transverse convexity and each longitudinal and transverse
8 concavity is located on the bottom surface of the upper layer, (2) the sharpness or
9 shallowness of each such convexity or concavity, i.e., its radius or radii of io curvature, (3) the length or wavelength of each such convexity or concavity as
! i measured from a point where it begins to a point where it ends, (4) the amplitude,
12 i.e., the greatest height of each such convexity or the greatest depth of each such
13 concavity, and (5) the firmness or compressibility of the upper layer material with4 which each such convexity or concavity is formed. These variables are some of 5 the primary means by which the effects of the shoe on the user are controlled. 6 These effects comprise primarily (1) the degree of softness or hardness felt by the7 user's foot throughout each step while wearing the shoe, (2) the amount of energys and effort needed for the user to complete each step, and (3) the amount of muscle9 use, control and coordination necessary for the user to maintain the user's balance0 throughout each step. 1 [00019] The degree of softness or hardness felt by the user's foot 2 immediately after the heel strike is controlled primarily by a longitudinal concavity
1 located in the heel region. This longitudinal concavity is typically relatively large,
2 i.e., it typically has a long length, a large radius or radii of curvature, and a large
3 amplitude. This relatively large longitudinal concavity allows a relatively thick
4 lower layer to be used in the heel region that can absorb and soften the initial heel
5 strike of each step. Whereas each longitudinal concavity and each transverse
6 concavity imparts a relatively soft feel to the user's foot while walking, each
7 longitudinal convexity and each transverse convexity imparts a relatively hard feel
8 to the user's foot while walking. This relative hardness is due to the decreased
9 thickness of the soft, highly compressible lower layer at each location where a io longitudinal or transverse convexity occurs.
] i [00020] The amount of energy and effort required by the user in each ϊ2 step is related to the degree of softness or hardness felt by the user as discussed in
13 the preceding paragraph insofar as each longitudinal or transverse concavity
14 corresponds to a softer feel which, in turn, requires more energy and effort to is overcome in each step. 6 [00021] The amount of muscle use, control and coordination necessary 7 for the user to maintain the user's balance throughout each step increases in directs proportion to each one of the following: (1) increased size, primarily in 9 wavelength and amplitude, of the longitudinal concavity and/or transverse 0 concavity and (2) increased compressibility of the lower layer. Increased 1 longitudinal and/or transverse concavity size in the form of greater amplitude2 corresponds to a thicker lower layer. The compressibility of the lower layer is a
physical property inherent in the material out of which the lower layer is made. It is a measure of the readiness with which the lower layer compresses under a given load. A high compressibility means that the lower layer is highly compressible and can be compressed a high amount with relative ease. As the compressibility increases, the user must use more muscle control and coordination to maintain the user's balance during each step as the weight of the user compresses the lower layer. This compression is accompanied by a downward movement of the user's foot as it compresses the lower layer during each step. This downward compression movement requires balancing by the user to accommodate inherent longitudinal and transverse instability that accompanies the compression. This inherent longitudinal and transverse instability is also affected by the thickness of the lower layer. This thickness, as mentioned above, increases as longitudinal and/or transverse concavity size increases. As the thickness of the lower layer increases, the inherent longitudinal and transverse instability increases. Thus, longitudinal concavities and transverse concavities both contribute to a less stable walking nature of the shoe. The relative opposite effect is achieved with a longitudinal convexity and/or a transverse convexity. Each longitudinal convexity and/or transverse convexity in the upper layer corresponds to a relative thinness in the lower layer. This relative thinness in the lower layer means that the user is not required to engage in as much balancing effort as when the lower layer is thick, primarily because the amount of unstableness in the lower layer is decreased, i.e., the stableness of the lower layer is increased, where each longitudinal convexity and/or transverse convexity occurs in the corresponding upper layer. Thus,
1 longitudinal convexities and transverse convexities contribute to a more stable
2 walking nature of the shoe.
3 [00022] One of the primary objectives of shoes having midsoles as
4 disclosed herein is to provide fitness benefits to the user by requiring the user, by
5 merely walking, to exert more energy and effort than would otherwise be required
6 when walking while wearing conventional shoes, and to require the user to use,
7 control, and coordinate muscles in ways that such muscles would not be used,
8 controlled or coordinated when walking while wearing conventional shoes. Just as
9 walking on a sandy beach requires more energy and effort than walking on a hard, io flat surface, the relatively thick, highly compressible lower layer of the rnidsole in i ] the area of a longitudinal concavity and/or a transverse concavity requires that a
!2 user wearing shoes having such a midsole exert more energy and effort to walk j 3 than is required while wearing conventional shoes. The extra thickness and high
14 compressibility of the lower layer in the area of the longitudinal concavity and, if
15 present, the transverse concavity, further allows the shoes to flex more, both
16 transversely and longitudinally, than conventional shoes. In order for the user to
17 maintain the user's balance and a normal walking gait under such flexure s conditions, the user is required to use muscles and to control and coordinate9 muscles to an extent greater than is required when walking while wearing 0 conventional shoes. The use of such muscles in such a manner further imparts a ! fitness benefit to the user. These and other fitness benefits of the instant shoe2 include, among others: muscle strengthening and toning, better posture, improved3 cardiovascular health, less stress on joints, and improved circulation.

DESCRIPTION OF PREFERRED EMBODIMENTS [00047] The invention will now be described with reference to the preferred embodiment shown in FIGS. 1 and IA. This embodiment shows a shoe upper 106, a midsole 103, and an outsole 105 of the shoe. The outsole 105 is not part of the midsole 103. As shown in FIGS. 1 and IA, the outsole 105 is below the midsole 103 when the shoe is in its normal, upright position. This normal, upright position is shown with respect to the ground 100 in FIGS. 6B — 6D. As used herein, "above" and "below" refer to relative locations of identified elements when the shoe is in this normal, upright position as shown in FIGS. 6B - 6D. The midsole 103 is located between the shoe upper 106 and the outsole 105. [00048] The midsole 103, as shown in FIG. IA, comprises an upper layer 107 and a lower layer 109. The upper layer 107 and/or the lower layer 109 may each comprise two or more sub-layers. The upper layer 107 has a top surface 1 13 substantially opposite a bottom surface 115. Top surface 113 is shown in FIG.
7 A. Bottom surface 115 is shown in FIG. 7B. The lower layer 109 has a top surface 117 substantially opposite a bottom surface 121. Top surface 117 is shown in FIG. 7C. Bottom surface 121 is shown in FIG. 7D. The outsole 105 has a top surface 119 substantially opposite a bottom surface 123. As shown in FIGS. 1 and IA, when the shoe is in its normal, upright position, the lower layer 109 is below the upper layer 107 and the outsole 105 is below the lower layer 109. [00049] The shoe has a front tip 140 located at the farthest point toward the front of the shoe and a rear tip 142 located at the farthest point toward the rear of the shoe. The upper layer 107 includes a toe region 151 that extends substantially from the medial side of the shoe to the lateral side of the shoe at a location that begins in the vicinity of the front tip 140 and extends from there to a location that is approximately one third of the distance toward the rear tip 142. The lower layer 109 includes a toe region 161 that extends substantially from the medial side of the shoe to the lateral side of the shoe at a location that begins in the vicinity of the front tip 140 and extends from there to a location that is approximately one third of the distance toward the rear tip 142. The outsole 105 includes a toe region 171 that extends substantially from the medial side of the shoe to the lateral side of the shoe at a location that begins in the vicinity of the front tip 140 and extends from there to a location that is approximately one third of the distance toward the rear tip 142. [00050] The upper layer 107 includes a heel region 153 that extends substantially from the medial side of the shoe to the lateral side of the shoe at a
location that begins in the vicinity of the rear tip 142 and extends from there to a location that is approximately one third of the distance toward the front tip 140. The lower layer 109 includes a heel region 163 that extends substantially from the medial side of the shoe to the lateral side of the shoe at a location that begins in the vicinity of the rear tip 142 and extends from there to a location that is approximately one third of the distance toward the front tip 140. The outsole 105 includes a heel region 173 that extends substantially from the medial side of the shoe to the lateral side of the shoe at a location that begins in the vicinity of the rear tip 142 and extends from there to a location that is approximately one third of the distance toward the front tip 140. [00051 ] The upper layer 107 includes a middle region 152 that extends substantially from the medial side of the shoe to the lateral side of the shoe at a location that extends approximately between the toe region 151 and the heel region 153. The lower layer 109 includes a middle region 162 that extends substantially from the medial side of the shoe to the lateral side of the shoe at a location that extends approximately between the toe region 161 and the heel region 163. The outsole 105 includes a middle region 172 that extends substantially from the medial side of the shoe to the lateral side of the shoe at a location that extends approximately between the toe region 171 and the heel region 173. [00052] Typically, the lower layer 109 of the midsole 103 is on average thicker in the heel region 163 than it is in the toe region 161. Typically, the thickness of the lower layer 109 is less than about 45 millimeters thick in the heel
1 region 163 and has an average thickness in the heel region 163 of at least about 6.5
2 millimeters, and is less than about 25 millimeters thick in the middle region 162
3 and the toe region 161 and has an average thickness in the middle region 162 and
4 the toe region 161 of at least about 3 millimeters. The upper layer 107 has a first
5 density and the lower layer 109 has a second density different from the first density
6 and is typically less dense than the first density. The upper layer 107 has a first
7 compressibility and the lower layer 109 has a second compressibility that is s different from the first compressibility. The compressibility of the lower layer 109
9 is typically relatively high. Due to this relatively high compressibility, the lower
10 layer 109 undergoes a relatively high amount of deformation when subjected to a
11 given load. The upper layer 107 is typically made from polyurethane, polyvinyl j 2 chloride, rubber or thermal plastic rubber. However, the upper layer 107 can be
13 made from any other material without departing from the scope of the present
14 invention. Typically the upper layer 107 will have a density of between about is 0.400 and about 0.500 grams per cubic centimeter and a durometer between about 6 50 and about 75 Shore A (ASTM D2240). The lower layer 109 is made of a7 compressible and deformable yet resilient material which may or may not be the 8 same material of which the upper layer 107 is made. Typically the lower layer9 109 will have a density of between about 0.325 and about .419 grams per cubic0 centimeter and a durometer between about 15 and about 38 Shore A (ASTM! D2240). The top surface 113 of the upper layer 107 is typically positioned below2 an insole board (not shown) which is typically positioned below a sockliner 101.3 The upper layer 107 has a bottom surface 115 that may be connected to the top
surface 117 of the lower layer 109 by either friction and/or an adhesive and/or other similar means. Alternatively, substantially the entire bottom surface 115 of the upper layer 307 may be molded to substantially the entire top surface 117 of the lower layer 109. [00053] The bottom surface 115 of the upper layer 107, as shown in FIG. IA, has a longitudinal convexity 180 that comprises at least a downward curve 190 located in at least a portion of the toe region 151. "Downward curve," as used here and throughout this specification, unless otherwise noted, refers to a direction that moves toward the ground 100 from any specified location on the shoe when viewed while moving from the front tip 140 to the rear tip 142 and while the shoe is oriented in its typical upright position where the bottom surface 123 of the outsole 105 is in unloaded contact with the ground 100. The upper layer has a frontmost point 150 and a rearmost point 154. Downward curve 190 of longitudinal convexity 180 begins at, or near the vicinity of, the frontmost point 150 of the upper layer 107 and gradually and continuously descends downwardly from there through at least a portion of the toe region 151. The portion of the upper layer 107 indicated by lines extending from, and associated with, reference numeral 180 indicates the approximate range wherein longitudinal convexity 180 is typically primarily located. Longitudinal convexity 180 may, or may not, be entirely located within the range indicated by the lines extending from, and associated with, reference numeral 180. Longitudinal convexity 180, as shown in FIG. IA, is relatively shallow due to its large radius, or radii, of curvature. Longitudinal convexity 180 may comprise a curve or curves in addition to
1 downward curve 190. The radius of curvature throughout longitudinal convexity
2 180 may be completely constant, may have one or more constant portions mixed
3 with one or more non-constant portions, or may be completely non-constant.
4 Downward curve 190, as well as any other curve or curves that are part of
5 longitudinal convexity 180, may, at any point on any of those curves, have a slope
6 somewhere between negative infinity and positive infinity and can include a slope
7 that is zero, gradual, moderate, steep, vertical, horizontal or somewhere between s any of those amounts. Although downward curve 190 of longitudinal convexity 9 180 is shown in FIG. IA as beginning near the frontmost point 150, downward
10 curve 190 of longitudinal convexity 180 may instead begin at some other location
11 on the upper layer 107. Although longitudinal convexity 180 is shown in FIG. IA
12 as ending at a location in the middle region 152 or the location where the middle π region 152 transitions into the heel region 153, longitudinal convexity 180 may end
14 at some other location on the upper layer 107.
15 [00054] The bottom surface 115 of the upper layer 107, as shown in
16 FIG. IA, has a longitudinal concavity 182 that comprises at least a portion of an
17 upward curve 193 located in at least a portion of the heel region 153. "Upward 8 curve," as used here and throughout this specification, unless otherwise noted,9 refers to a direction that moves away from the ground 100 from any specified0 location on the shoe when viewed while moving from the front tip 140 to the rear 1 tip 142 and while the shoe is oriented in its typical upright position where the2 bottom surface 123 of the outsole 105 is in unloaded contact with the ground 100.3 In this preferred embodiment, longitudinal concavity 182 further comprises at least
1 a downward curve 194. Upward curve 193 may or may not be contiguous with
2 downward curve 194. Upward curve 193 ascends upwardly in at least a portion of
3 the heel region 153. Downward curve 194 descends downwardly in at least a
4 portion of the heel region 153. The portion of the upper layer 107 indicated by
5 lines extending from, and associated with, reference numeral 182 indicates the
6 approximate range wherein longitudinal concavity 182 is typically primarily
7 located. Longitudinal concavity 182 may, or may not, be entirely located within
8 the range indicated by the lines extending from, and associated with, reference
9 numeral 182. Longitudinal concavity 182 may comprise a curve or curves in so addition to a portion of upward curve 193 and downward curve 194. The radius of
! i curvature throughout longitudinal concavity 182 may be completely constant, may
12 have one or more constant portions mixed with one or more non-constant portions,
13 or may be completely non-constant. Upward curve 193, downward curve 194, as4 well as any other curve or curves that are part of longitudinal concavity 182, may, s at any point on any of those curves, have a slope somewhere between negative6 infinity and positive infinity and can include a slope that is zero, gradual, 7 moderate, steep, vertical, horizontal or somewhere between any of those amounts,s Although upward curve 193 is shown in FIG. IA as beginning at a location where9 the toe region 151 and the middle region 152 transition into one another, upward0 curve 193 could instead begin at some other location on the upper layer 107. 1 Although upward curve 193 is shown in FIG. IA as ending at a location in the heel2 region 153, upward curve 193 may instead end at some other location on the upper3 layer 107. Although downward curve 194 is shown in FIG. IA as beginning in the
1 heel region 153 and ending in the vicinity of the rearmost point 154 of the upper
2 layer 107, downward curve 194 may instead begin at some other location on the
3 upper layer 107 and end at some other location on the upper layer 107.
4 Longitudinal convexity 180 may or may not be contiguous with longitudinal
5 concavity 182.
6 [00055] In another embodiment, the upper layer 107 has a bottom
7 surface 115 A. Bottom surface 115A differs from bottom surface 115 in that.
8 bottom surface 115, as can be seen in FIGS. 2, 3, 4, and 5, is straight when viewed
9 along a transverse axis at any location along its surface. As used herein, a
!0 transverse axis is a straight line that extends from the medial side of the shoe to the π corresponding lateral side of the shoe in a plane that is parallel to the ground 100
12 when the shoe is not bearing any load and is in its normal, upright orientation.
13 Some examples of such transverse axes are indicated by the straight lines that
14 represent bottom surface 115 in FIG. 7B5 the straight lines that represent top is surface 1 17 in FIG. 7C, and the straight lines that represent bottom surface 121 in 6 FIG. 7D. As can be seen in FIGS. 2A - 5A, however, bottom surface 115A is7 convex when viewed along a transverse axis at any location along bottom surfaces 1 ISA. This convex shape of bottom surface 115A forms a transverse convexity9 186 which is shown in FIGS. 2 A - 5 A. Transverse convexity 186 lies only in0 vertical, transverse planes that extend from any local medialmost point of the shoe1 to a corresponding local lateralmost point of the shoe at any location between the2 front tip 140 and the rear tip 142 when the shoe is in its normal, upright position.3 When transverse convexity 186 is present, it is present in addition to longitudinal
1 convexity 180 and longitudinal concavity 182. When bottom surface 115 A is
2 present, lower layer 109 has a top surface 117A that substantially conforms to and
3 mirrors bottom surface 115 A. Transverse convexity 186 may be located in any
4 portion or portions of the toe region 151, middle region 152 or heel region 153 of
5 the upper layer 107. Transverse convexity 186 may also be present throughout the
6 entire upper layer 107. The shape of transverse convexity 186 may be any shape
7 as described herein for longitudinal convexity 180. In any given bottom surface
8 115 A, the shape of transverse convexity 186 may change as the location of
9 transverse convexity 186 changes with respect to the front tip 140 and the rear tip io 142. i ! [00056] In another embodiment, the upper layer 107 has a bottom
12 surface 115B. As can be seen in FIGS. 2B - 5B, bottom surface 115B is concave
13 when viewed along a transverse axis at any location along bottom surface 115B. 4 This concave shape of bottom surface 115B forms a transverse concavity 187
15 which is shown in FIGS. 2B — 5B. Transverse concavity 187 lies only in vertical, 6 transverse planes that extend from any local medialmost point of the shoe to a 7 corresponding local lateralmost point of the shoe at any location between the front8 tip 140 and the rear tip 142 when the shoe is in its normal, upright position. When9 transverse concavity 187 is present, it is present in addition to longitudinal0 convexity 180 and longitudinal concavity 182. When bottom surface 115B is1 present, lower layer 109 has a top surface 117B that substantially conforms to and2 mirrors bottom surface 115B. Transverse concavity 187 may be located in any3 portion or portions of the toe region 151, middle region 152 or heel region 153 of
the upper layer 107. Transverse concavity 187 may also be present throughout the entire upper layer 107. The shape of transverse concavity 187 may be any shape as described herein for longitudinal concavity 182. In any given bottom surface 115B, the shape of transverse concavity 187 may change as the location of transverse concavity 187 changes with respect to the front tip 140 and the rear tip 142. In any given bottom surface 115B, transverse concavity 187 may be present in addition to transverse convexity 186. In any given bottom surface 115 A, transverse convexity 186 may be present in addition to transverse concavity 187. [00057] The outsole 105 may curve upwardly in the heel region. The outsole 105 has a frontmost point 170 and a rearmost point 174. When the shoe is in its typical upright, unloaded state, the frontmost point 170 and the rearmost point 174 are both relatively high above the ground 100. From a point at or near the vicinity of the frontmost point 170, the outsole 105 has a gradual downward curve 195 that continues through at least a portion of the toe region 171 of the outsole 105. Starting in the middle region 172, the outsole 105 has a gradual, upward curve 196 that continues to curve upward through at least a portion of the heel region 173 of the outsole 105. This gradual upward curve 196 typically continues until the outsole 105 approaches the vicinity of the rear tip 142 of the shoe. This upward curve 196 is typically sharper than downward curve 195 in the toe region 171. Upward curve 196 may be substantially sharper than shown in FIG. IA or substantially shallower than shown in FIG. IA. The outsole 105 has a bottom surface 123 that typically contains grooves and/or patterns for optimal traction and wear.
[00058] FIG. 2 shows a front elevation view in cross section of the midsole 103 shown in FIG. 1 along line 2-2 in the direction of the appended arrows. As shown in FIG. 2, the bottom surface 115 of the upper layer 107 substantially conforms to and mirrors the top surface 117 of the lower layer 109. The shape of the bottom surface 115 and the top surface 1 17 at line 2-2 is shown in FIG. 2 by a substantially horizontal line that extends from the lateral side of the midsole 103 to the medial side. [00059] FIG. 3 shows a front elevation view in cross section of the midsole 103 shown in FIG. 1 along line 3-3 in the direction of the appended arrows. As shown in FIG. 3, the bottom surface 115 of the upper layer 107 substantially conforms to and mirrors the top surface 117 of the lower layer 109. The shape of the bottom surface 115 and the top surface 117 at Jine 3-3 is shown in FIG. 3 by a substantially horizontal line that extends from the lateral side of the midsole 103 to the medial side. [00060] FIG. 4 shows a front elevation view in cross section of the midsole 103 shown in FIG. 1 along line 4-4 in the direction of the appended arrows. As shown in FIG. 4, the bottom surface 115 of the upper layer 107 substantially conforms to and mirrors the top surface 117 of the lower layer 109. The shape of the bottom surface 115 and the top surface 117 at line 4-4 is shown in FIG. 4 by a substantially horizontal line that extends from the lateral side of the midsole 103 to the medial side.
1 [00061] FIG. 5 shows a front elevation view in cross section of the
2 midsole 103 shown in FIG. 1 along line 5-5 in the direction of the appended
3 arrows. As shown in FIG. 5, the bottom surface 115 of the upper layer 107
4 substantially conforms to and mirrors the top surface 117 of the lower layer 109.
5 The shape of the bottom surface 115 and the top surface 1 ϊ 7 at line 5-5 is shown in
6 FIG. 5 by a substantially horizontal line that extends from the lateral side of the
7 midsole 103 to the medial side.
8 [00062] As shown in cross sections in FIGS. 1 - 5, the thickness of the
9 midsole 103 varies and generally increases from the toe regions 151 and 161 to the io heel regions 153 and 163. i ] [00063] In preferred embodiments, the top surface 1 17 of the lower
12 layer 109 of the midsole 103 is in substantially continuous contact with the bottom
13 surface 115 of the upper layer 107 of the midsole 103. Due to this substantially
14 continuous contact between top surface 117 and bottom surface 115 in these
15 preferred embodiments, top surface 117 substantially conforms to and mirrors
16 bottom surface 115. In other embodiments, such substantially continuous contact s 7 between top surface 1 17 and bottom surface 115 may not be present.
18 [00064] In normal use of the shoe, each forward step taken by the user
19 begins when the heel region 173 of the outsole 105 begins to make contact with the 0 ground 100. The lower layer 109 of the midsole 103 in the heel region 163 that is 1 made of less dense and more readily compressible material then begins to 2 compress and deform, allowing the heel of the user's foot to sink toward the
1 ground 100 to a greater extent than it would sink while wearing a conventional
2 shoe. Due to longitudinal concavity 182, the lower layer 109 is relatively thick in
3 the heel region 163. Since this relatively thick heel region 163 of the lower layer
4 109 is also relatively soft and highly compressible, it mimics the effect of walking
5 on a sandy beach, thereby requiring the user to exert more energy while walking
6 than would be required when walking while wearing conventional shoes.
7 Additionally, since the heel region 163 of the lower layer 109 is relatively thick
8 and highly compressible, it has a degree of inherent longitudinal and transverse
9 instability that is not present in conventional shoes. This inherent instability forces
10 the user to engage in a balancing effort and use muscles and muscle control and
11 coordination to maintain a normal walking gait that would not be required with
12 conventional shoes.
13 [00065] As the step continues, the user's weight shifts to the middle
H regions 152, 162, and 172 and the shoe rolls forward in a smooth motion without is the user having to overcome any abrupt pivot point. The lower layer 109 of the
16 midsole 103 in the middle region 162 then compresses and deforms, allowing the π user's foot in that region to sink toward the ground 100 more than it would sink if is the user were wearing conventional shoes. As the step continues, the user's weight
19 then shifts to the toe regions 151, 161, and 171. The lower layer 109 of the
20 midsole 103 in the toe region 161 then compresses and deforms, allowing the
2) user's foot in that region to sink toward the ground 100 more than it would sink if
22 the user were wearing conventional shoes. As shown in the toe region 151 and
23 middle region 152 in FIG. 1 , longitudinal convexity 180 limits and decreases the
1 thickness of the highly compressible lower layer 109 in the corresponding toe
2 region 161 and middle region 162 of the lower layer 109. This decrease in
3 thickness of the lower layer 109 results in an increase in stability in the toe region
4 161 and middle region 162. The user then completes the step by pushing off with
5 the forefoot ball of the user's foot. All of this simulates the effect, and imparts the
6 fitness benefits, of walking on a sandy beach or on a giving or uneven soft surface
7 regardless of the actual hardness of the surface.
8 [00066] FIGS. 6A - 6D show a side elevation exterior view of a
9 representative shoe that embodies the instant invention. This exterior view io includes a curved line that corresponds to the shape of the bottom surface 115 of
] i the upper layer 107 and further corresponds to the shape of top surface 117 of the
12 lower layer Ϊ09. This curved line is indicated by reference numerals 115 and 117.
13 FIG. 6A shows this representative shoe in a fully unloaded state. FIGS. 6B, 6C,
14 and 6D show this representative shoe undergoing normal loading that occurs when
15 a user walks while wearing the shoe. 6 [00067] In FIGS. 6 A - 6D, the straight lines identified by, respectively, 7 reference numerals 601 A - 601 D, 602 A - 602D, and 603 A - 603D each represent8 the thickness of the upper layer 107 at the location where each such straight line9 601 A - 601D, 602A - 602D, and 603A - 603D appears. The straight lines0 identified by, respectively, reference numerals 604A - 604D3 605A - 605D, and1 606 A - 606D each represent the thickness of the lower layer 109 at the location
1 where each such straight line 604A - 604D, 605 A - 605D, and 606A - 606D
2 appears.
3 [00068] As shown in the unloaded state in FIG. 6A, the upper layer 107
4 and lower layer 109 are not undergoing any compression. As also shown in FIG.
5 6A, the outsole 105 is not undergoing any deflection or deformation. In this fully
6 uncompressed state, the thickness of the upper layer 107 and the thickness of the
7 lower layer 109 are each at their respective maximum thickness. This maximum
8 thickness is indicated by, and corresponds to, the length of each straight line 601 A
9 — 606A, each one of which is at its maximum length as shown in FIG. 6A.
10 [00069] FIG. 6B shows the representative shoe in an orientation where
11 the user's heel (not shown) is imparting a load in the heel regions 153, 163, and
12 173, shown in FIGS. 1 and IA. Under this loading condition, the heel region 153
13 of the upper layer 107 is undergoing a relatively small amount of compression.
14 This relatively small amount of compression results in a relatively small decrease
15 in the thickness of the heel region 153 of the upper layer 107. This relatively small Ϊ6 decrease in thickness is indicated by 60 IB. Under this same loading, the heel
17 region 163 of the lower layer 109 is undergoing a relatively large amount of is compression. This relatively large amount of compression results in a relatively
!9 large decrease in the thickness of the heel region 163 of the lower layer 109. This 0 relatively large decrease in thickness is indicated by 604B. Under this same j loading, the heel region 173 of the outsole 105 is undergoing a relatively large2 amount of deflection. This relatively large amount of deflection in the heel region
1 173 of the outsole 105 is caused by the heel region 173 conforming to the ground
2 100 as it bears the load of the user. This deflection and conformity of the heel
3 region 173 of the outsole 105 is indicated by the straight portion of the outsole 105
4 where it contacts the ground 100 as shown in FIG 6B.
5 [00070] FIG. 6C shows the representative shoe in an orientation where
6 the user's foot (not shown) is imparting a load in the middle regions 152, 162, and
7 172, shown in FIGS. 1 and IA. Under this loading condition, the middle region
8 152 of the upper layer 107 is undergoing a relatively small amount of compression.
9 This relatively small amount of compression results in a relatively small decrease io in the thickness of the middle region 152 of the upper layer 107. This relatively ϊ ] small decrease in thickness is indicated by 602C. Under this same loading, the
12 middle region 162 of the lower layer 109 is undergoing a relatively large amount
13 of compression. This relatively large amount of compression results in a relatively 4 large decrease in the thickness of the middle region 162 of the lower layer 109.5 This relatively large decrease in thickness is indicated by 605C. Under this same6 loading, the middle region 172 of the outsole 105 is undergoing a relatively large7 amount of deflection. This relatively large amount of deflection in the middles region 172 of the outsole 105 is caused by the middle region 172 conforming to the9 ground 100 as it bears the load of the user. This deflection and conformity of the0 middle region 172 of the outsole 105 is indicated by the straight portion of the1 outsole 105 where it contacts the ground 100 as shown in FIG 6C.
1 [00071] FΪG. 6D shows the representative shoe in an orientation where
2 the user's foot (not shown) is imparting a load in the toe regions 151, 161, and 171,
3 shown in FIGS. 1 and IA. Under this loading condition, the toe region 151 of the
4 upper layer 107 is undergoing a relatively small amount of compression. This
5 relatively small amount of compression results in a relatively small decrease in the
6 thickness of the toe region 151 of the upper layer 107. This relatively small
7 decrease in thickness is indicated by 603D. Under this same loading, the toe s region 161 of the lower layer 109 is undergoing a relatively large amount of
9 compression. This relatively large amount of compression results in a relatively
10 large decrease in the thickness of the toe region 161 of the lower layer 109. This
11 relatively large decrease in thickness is indicated by 606D. Under this same
12 loading, the toe region 171 of the outsole 105 is undergoing a relatively large
13 amount of deflection. This relatively large amount of deflection in the toe region !4 171 of the outsole 105 is caused by the toe region 171 conforming to the ground
15 100 as it bears the load of the user. This deflection and conformity of the toe
16 region 171 of the outsole 105 is indicated by the straight portion of the outsole 105 π where it contacts the ground 100 as shown in FIG 6D. is [00072] While the foregoing detailed description sets forth selected
