JOSEF SEIF 9 fl7 ATTURNE 5 SHOE CONSTRUCTION INCORPORATING CUSHIONED SOCK LINING This invention relates to footwear construction and in particular to a shoe fabrication incorporating a cushioned sock lining. The sock lining so incorporated forms an integral part of the shoe construction and provides added foot comfort besides being an efficient and economical means for shoe manufacture.
Various and sundry devices have been employed in the footwear industry for alleviating or preventing irritation and soreness to the wearers feet, occasioned by a tired, burning sensation which is especially prevelant in connection with ladies high-heeled shoes. The use of foot pads as cushioning devices commonly inserted separately within the shoe, have proven generally ineffective and usually slip or shift within the shoe due to the forces exerted by the weight of the wearer. Therefore such devices are uncomfortable and ineffective in providing complete foot comfort.
Conventional means of shoe manufacture also incorporate such cushioning devices directly into the shoe, usually by adhesively positioning a pad made of foam rubber or felt material to the inner sole of theshoe. This method of so fabricating the shoe has certain inherent disadvantages, among them that of increased stiffness to the foot wear; additional operations or steps in the manufacture of the shoe thereby increasing the unit costs, and finally these pads themselves have not proved entirely successful because after continued usage the foam rubber or felt material from which they are constructed becomes so compressed and/or repositioned by the weight of the wearer's foot that it loses its resiliency and cushioning effect.
The shoe construction of this present invention incorporating a cushioned sock lining overcomes the above-mentioned disadvantages of the prior art, and provides a sock lining which gives continued foot comfort throughout the life of the shoe.
The present invention encompasses a shoe construction having an upper inner shoe lining which is stitched along its lower periphery to a sock lining filled with a cushioning material. An inner sole of the shoe is adhesively attached to the outer portion of the sock lining and an outer sole is affixed to the inner sole. Additionally transverse stitching is placed through the sock lining and cushioning material to prevent the shifting or repositioning of the cushioning material especially under those areas of the wearer's foot where the weight is concentrated.
It is therefore an object of the present invention to provide a shoe construction incorporating a cushioned sock lining of the general character described herein which is not subject to the aforementioned disadvantages.
Specifically it is an object of the instant invention to provide a shoe construction incorporating a cushioned sock lining which will add to the wearers foot comfort and will not increase the stiffness of the shoe.
It is a further object of the present invention to provide a shoe construction wherein the cushioning material will not shift or slide within the shoe nor lose its resiliency and cushioning effect.
Another object of this invention is to provide a show construction incorporating a cushioned sock lining wherein the individual manufacturing operations and resultant cost of manufacture is reduced.
The above and other objects, features and advantages of the present invention will be apparent from the following description of the preferred embodiment considered in connection with the accompanying drawings.
In the accompanying drawings in which are shown some of the various possible embodiments of the invention:

FIG. 8 is a cross-sectional view taken along line 8-8 of FIG. 7 and shows the outer sole afiixed to the inner sole and the outer edge of the shoe vamp interlaid between the inner sole and outer sole.
Referring now in detail to the drawings, the reference numeral l0 denotes generally the cushioned sock lining. The shoe construction in accordance with this invention incorporating the cushioned sock lining l0 encompasses the utilization of a shoe vamp 12 cut or shaped to conform to the particular shoe last employed for the desired size and style of shoe. The shoe vamp l2 constitutes substantially that portion of the shoe which covers the instep and toes, and is preferably made of leather or other lightweight durable synthetic material. A vamp lining 14 is positioned contiguous to the shoe vamp 12 and is attached to the shoe vamp 12 along a coterminus edge 16 as by sewing same thereto to form stitches 18. The coterminus edge 16 defines a central shoe opening 17, through which the wearers foot enters the shoe. A gore 20 is provided along the coterminus edge 16 and an elastic material 22 is interposed between the shoe vamp 12 and vamp lining l4 and is sewn therein such that the elastic material 22spans the gore 20 and provides added flexibility to the central shoe opening 17 to facilitate the entry of the wearer's foot into the shoe. The vamp lining 14, similar to the shoe vamp 12, is preferably made from leather or other durable lightweight synthetic material.
The cushioned sock lining 10 is fabricated from a base sheet 24 and an upper sheet 26, both sheets being cut to and conforming with the outline of the shoe sole, which in turn, will be dependent upon the shoe size and style. A common outer edge 32 of the base sheet 24 and upper sheet 26 are sewn together as with a needle 36 and a common thread 37 to form stitches 19; the envelope so formed encloses a filler or cushioning material 28. Additionally, an auxiliary seam 30 may be stitched through the cushioned sock lining 10 between any two points along the outer edge 32 of the sock lining 10 to thus segregate the cushioning material 28 into distinct and separate units (see FIG. 2). This segregation of the cushioning material 28 particularly in those areas where the wearer's weight distribution tends to be concentrated, e.g. the ball of the foot, or heel, and will thus prevent the cushioning material 28 from being repositioned or moved from those areas. The illustration of FIG. 1 shows the auxiliary seam 30 segregating a generally oval shaped portion of the cushioning material 28 underlying the ball of the wearers foot. The bottom sheet 24 of cushioned sock lining 10 is preferably made of a cloth material and the upper sheet 26 which will be adjacent and in contact with the wearer's foot is preferably made of a smooth vinyl, leather, or other nonirritating and smooth surface finish material.
The lower peripheral edge 34 of the vamp lining 14 is sewn to the cushioned sock lining 10 along the outer edges 32 of said sock lining 10 as shown in FIG. 3 wherein the needle 36 and common thread 37 are specifically illustrated. After the vamp lining 14 has been sewn to the cushioned sock lining 10, a pocket 38 will be formed between the vamp lining l4 and cushioned sock lining 10, said pocket being suitable for accommodating a shoe last." The shoe vamp 12 is turned downwardly over the shoe last and vamp lining l4 and an additional rear quarter panel 40 of the same material as the shoe vamp 12, is sewn between two extremities 42 and 43 of the shoe vamp 12 to complete the outer shoe covering. A peripheral edge 44 of the shoe vamp 12 extends below the cushioned sock lining l and thereby defines a recessed area under the sock lining for accommodating an inner sole 46 which is bonded, by means of an appropriate adhesive substance 52, to the base sheet 24 of the cushioned sock lining 10. The adhesive may be any of the conventional glues used in the shoe industry. The peripheral edge 44 of shoe vamp 12 may then be turned inwardly or folded around the inner sole 46. Several cuts or slits 48 may be provided in the peripheral edge 44 so as to permit the peripheral edge 44 to overlap and conform to the curvature of the inner sole 46 and thus produce a neat appearance. An outer sole 48 having an attached heel 50 is then affixed to the inner sole 46 by means of the adhesive bonding substance 52.
It is to be noted that the filler or cushioning material 28 may consist of polyurethane foam or other material having similar characteristics. it should also be apparent that the abovedescribed shoe construction will provide a soft, pliable and comfortable cushioned sock lining without increasing the stiffness of the shoe and additionally provides an economical and improved shoe construction.
The above-cited embodiment is intended as exemplary and while it has described the invention with a specific implementation thereof, other modifications and various changes might be made in the embodiment as so set forth and will be apparent to those skilled in the art.
It should therefore be understood that all material herein described or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
