Patented Dec. 1o, 1929 UNITED STATES ISIDORE SIMON, F CHICAGO, ILLINOIS SHOE Application led Qctober 12, 1927. Serial I o. 225,763.
This invention pertains to the general class oi devices for correcting foot ailments. It is known that devices oi this character have heretofore been produced; however, as far as t; applicant is aware, no devices are in existence which embody the scientific principles as applied to shoes and their innersoles as disclosed in this application. f
An object of the present invention is to pre- 1U vent and correct abnormal distribution and abnormal direction of forces in the various parts of the human toot.
A further object of this invention is th .production of devices, particularly shoes and their innersoles, for preventing, correcting and checking undue strains and stresses and abnormal distribution of forces in and between the parts of the human foot, and for treating feet subjected to said abnormal strains andstresses and forces.
A further object of this invention `is a method for producing devices, particularly' shoes and their innersoles, for the purpose of preventing, correcting, checking abnormal strains and stresses and abnormal distribution of forces in the human foot and for treating feet subjected to other than normal forces.
A further object of this invention is the production of apparatus for producing devices, particularly shoes and their innersoles,
for the purpose of preventing, correcting and checking abnormal strains and stresses and abnormal distribution of forces in the human footand for treatingfeet subjected to abnormal forces.
Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.
To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims. l

Fig. ll'is a section on line 11-11 of Fig. 8, and in addition thereto showing the position of the wedge, the concavity at the heel and the split innersole;
Fig. 12 is a detail View of the wedge; and
Fig. 13 is a top plan view of a different form of the invention illustrating a depression in an innersole for the lateral tubercle of the oscalsis as Well as the median tubercle.
In a preferred form of the invention, the inner sole 25 (see Fig. 2) is embossed at 26 before being applied to the last, to form a counterbalance for the base of the fifth metatarsal bone of the foot, the base being' a .weight bearing point of the outer component part of the foot. The innersole is then split' into upper part 38 and lower part 37 (see Fig. 11) from heel to lshank and a leather wedge 27 inserted or a filler at the inner side of the heel otherwise provided, its greatest thickness being on the medial or inner side f yof the foot. The purpose of this wedge or iller is to counterbalance the lateral'tubercle of the oscalsis located in the outer component part of the foot. Cooperative with the wedge 27 and the boss 26 is the U-shaped or semi-circular cut-away portion 28 (see Figs. 5 and 12). Cooperating therewith is i the concave depression 29. One of the puron the medial side of the center line.
poses of parts 28 and 29 is to obtain a proper and perfect support at the heel,part1culxrarllly e parts, 28 and 29 receive the median tubercle of the. foot. This allows the wedge 27 to extend at least to the center line or further if desired in order that the roper angle and vsupport at the heel may be o tained in aggravated and especial cases. However, in the preferred embodiment, the transverse inclined plane originates at the center line. The parts28 and 29 furthermore relieve the median tubercle of undue strain and'stresses with attendant tenderness and soreness so .common when ordinary shoes are worn and .particularly shoes of this general character.
The pressure on the tip of the tubercle `is vobviously greatly reduced or relieved entirely and the weight 1s carried over a much larger surface above and immediately surrounding the tubercle. It is obvious that other shapes of su ports may be substituted for the wedge 27, t e wedge being merely the preferred embodiment.
The innersole 25is embossed before being I applied to the last. The embossed portion 26 is held in place by a boss being formed of vulcanized rubber or other plastic sub- Ysizes and styles of foot wear, the boss being maintained by a vulcanized or other plastic compound.
A new method of making shoes is thus provided in which the inner sole yforms a geometrical counterbalanc'e for the weight bearing points of the outer component part yof the foot. The embossed portion 26 and wedge 27 form the Weight bearing points for the inner component part of the-foot, the
' at 33, the
boss 30 and wedge 27 occurring in the innersole proper, leaving the interior side of the innersole a plain flat surface covered with canvas or other suitable material 31 interfering in no way with the channeling of the innersole, and not depending in any Vway upon the cork-gumfiller 32 used in shoe construction to support or maintain the boss 30 or the wedge 27. The outer sole is shown heel of the shoe at 34 and the upper at'140. l
afl-he invention may be carried out on a last 35 with a depression as at 36 (Fig. 8) to receive the innersole with the embossed portion 26, the greatestelevation of which is located at a point on the center line of the foot opposite the shafts of the second and third metatarsal bones, respectively, at the junction of their medial and distal thirds. At this point is formed one angle of anisosceles triangle, the base and head of the fth metatarsal bone being the other two points, the base of the triangle extending from the point of juncture mentioned above to the head of the fifth metatarsal. This formation of the depression 36 is accomplished by tooling out the last to accommodate the embossed portion 26 on the innersole.
The last is further formed with an elevation or.boss 39 located approximately centrally of the heel portion. This elevation or boss-like formation fits into the concavity of the depression 29 in the heel seat of the innersole.
The heel of the lastis further shaped to receive the elevation on the innersole caused by the wedge by cutting down the wood of the last shown at 41, forming two inclined planes 41 and 42, the plane 41 with its lower point located 'at the medial or inner border and its highest point terminating at the center line (see Fig. 8), and the longitudinal inclined plane 42 with its lowest point located at the posterior border 43 of the heel and terminating at the junction of the heel 44 and shank 45 with the exception of an additional elevation 39 at a point located beneath the median tubercle of the oscalsis to fit into the concavity or depression 29 on the heel seat of the innersole previously set forth.
It is obvbious that as a modification of the applicants invention, a thick innersole may be employed and instead of inserting a wedge on the innerside, the outer side may be cut away.
Fig. 6 shows a modification of applicants invention showing the depression 50 at lthe heel for the medial tubercle of the oscalsis applied to the ordinary shoe.
Fig. 7 is a further modification in which a depression 46 is further provided for the `lateral tubercle of the oscalsis. This form is preferable in many instances, inasmuch as the depression for the lateral tubercle is equivalent in certain respects to` a slightly higher wedge. Furthermore, the depression relieves undue strain on the lateral tubercle. The last for making this form is further provided with an elevation or boss opposite the lateral tubercle.
Fig. 13 is a top plan view of an innersole showing the position of the depression 46 for the lateral tubercle of the oscalsis.
Having thus described my invention, it is obvious that various immaterial modifications may b e made in the same without ,departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned.
