conimnnn SHANK. srrrrnfiiiiiliinii Application filed January .21

j The present invention relates, to shoes and invention being toprovide a shoe with a novel support incorporated therein for the metas tarsal arch.

To these and other ends, the invention consists of certain parts and combinations of parts, all of which will be hereinafter described: the novel features being pointed out in the appended claim.

In the drawings: Fig. 1 is an. underside view of alast used in t the present method;

last;

Fig.4: is a similar view'showing the arch 2 support in position;

Fig. 5 is a vertical section through the shoe after the insole and heel have been attached Figs. 6 and 7 arerespectively opposite sides of the arch support; and p Fig; 8 isan edge view of the arch support. In carrying out the illustrated embodiment of the invention, thereis providedra last 1 the under side of which between thetoe portion 1 and-the heel portion2 is formed witha.

' longitudinallyextending depression 3 curved in cross section and extending from a'polntfi immediately in rear of that portion whichls to form the portion of the shoe beneath the toe joints: 3 p p 7 The insole 5 of any style is tacked to the, last 'injtheiusuali manner preferably afterbeing moistened or tempered sothat it has flexibility and a roller or other device is then pressed against the insole 5 to forcethe insole into 1 l I the depression 3 of the last so that theouter face of the insole at the shank portion becomes depressed at 5 in the main arch of the shoe extendingto a point slightly "behind the joints of the metatarsal arch; After the insole has dried,the upper 6 is lasted by any suitable process, that shown being the ordinaryGood year process; g f

After thelasting,the usual trimming may take place and the bottomof the shoe willappear as shown in-,Fig.*3.-' The depression 5* Fig. 2 is a transverse section through the p p support and tacks, or fasteners 13 being Fig-3 is an underside View of the shoe after it has been lasted and before the arch sup- 7 port and the outer soleare attached;

depression 5 inthe inso1' 5: This" arch support in this instance is secured by a rivet 8 totlie fofwal'd end of a shank stiffener which, in this'instance,comprises an upperplate 9 and a lower reinforcing plate 10, the

, latter having a strengthening'rib 11 on its under side and being spot Welded at 12 tothe upper plate 9 so that theupper plate proattached. l a

I While the'invention is shown as embodied in what is known as aGoodyear welt shoe it is apparentthat theishoe i's notlimited to shoes made according tothe Goodyear proc-.

ess. This invention provides a raised portion on the 1111161 face of the 111SOleC0I1fOI'm nsolepf heishoe-is now filled by an support 7 refer-ably in the 'form' of a pie f eatlier haying'a"fiat'side 7% ancla *c'oii' z'sidfhth support conforming to the r jects beyond both ends thereof, the rivet-8' 'or rearend of said plate 9. The shoe may I then be filled in the'usual manner, the outer. i

ingto the shape of the foot at the-forward,-

1 The support acts merely upon the cords of a without reachingany of the jointsof the arch 7 V or the joint at the instep. The cords ofythe the three intermediate metatarsal'arch bones first and fifth'metatarsalbones are not acted upon or supported by the support.

This I causes the metatarsal, arch to assume 1ts corend of the main arch and extending substan-V rect arched position because the cordsfiare caused to function naturally.

What I claim as myinvention to secure b Letters Patent is:

A shoe aving its inner sole pressed upand desire wardly in the form of a projection, the front edge of the projection being in rear of the metatarsal arch and the sides. being spaced from the side edges oflthe inner face of the y inner sole at, opposite sidesv so that the projection pushes upwardly only on the cords leading to the three intermediate joints of the metatarsal arch while permitting the two outer cords leading to the arch to function 5 without upward pressure by the projection, and means for rigidly supporting said pressed up portion in t e shoe, said means comprising a long narrow shank of uniform width arranged between the inner and the outer soles, and having its rear end secured at the heel portion of the shoe, a lower reinforcing plate secured to the shank and extending longitudinally thereof and provided at its lower face with a longitudinal rib located at the central portion ofthereinforcing plate and a rigid projection arranged on the upper face of the shank on the arched portion thereof projecting beyond the forward end and side of the shank and lying in and conforming to the pressed up portion of the inner sole.
