Scholl, Chicago, Ill. Application January 10, 1936, Serial No. 58,457 3 Claims. My invention relates to shoes for foot-correc tive purposes, and has for its general objects to provide a novel and desirable shoe-construction especially suitable for use in the relief of weak - 5 or fallen arches, and which may be made by an e?icient and advantageous method. Sufferers with painful arch-conditions com monly wear what I may term “stock” arch-sup ports in “stock” shoes, in seeking relief, and even ll) where only one foot is so affected it is common practice to wear such appliances in both shoes, to avoid the uneven effect or “limp” in walking that annoyingly results from wearing only one. One of the more speci?c objects of my invention l. . (A is to so construct my improved shoes that wearing of a single arch-support is accommodated with (Cl. 36—-71) such shoes, with the appliances in place, not in— frequently result in conditions that militate se riously against the user’s comfort; against the sightly appearance of thev footwear, and even against best functioning of the appliances to give \ .m the desired foot-relief; and more specific objects of my invention are to provide my improved shoes in a normal condition for sale that makes them ?ttable, regardless of whether or not “stock” arch-supports are to be worn therein, exactly as a corresponding-size of “stock” shoes would be; that gives them advantage in normally affording a certain amount of arch-supporting effect which tends to prevent occurrence of arch-trou bles; and that permits of the substitution, at or after the time the shoes are purchased, of a “stock” arch support for the detachable “dummy” little or no such uneven effect. By “stock” shoes, as herein referred to, I allude arch-supportive structure of either or both of the to ready-made leather ones, internally contoured, normal shoes, with minimal discomfort, shoe “ for good fit upon a normal foot of the size for which the shoe’s length and width are indicated distortion, or other drawbacks. 20 Still another of my more speci?c objects is to by conventional standards; and what I term “stock” arch-supports are suitably stiffened or padded appliances (of which various speci?c con provide in such shoes a construction that permits their production on the same lasts that are used of the heel’s under-surface, and the waist of the appliance having its inner side widened and arched upward, conformably with the curvatures in the making of corresponding sizes and styles of stock shoes, and that may, if desired, insure :25 that any slight variation in the thickness of indi vidual dummy arch-supports used in making up a quantity of the shoes, will not affect the internal contouring of the ?nished foot-wear. To these ends, and for attaining other objects and advantages which will hereinafter become apparent, my- improved shoes have their founda tion-structures-—i. e., the permanently-united of the foot’s longitudinal arch. structions are commercially available) to be loosely inserted in the user’s shoes and to be positioned therein, in use, by coaction with the shoe and the foot; such an appliance being shaped in plan outline to underlie the foot’s width from .,0 a line just back of the ball of the foot to the rear Such appliances sole, heel, and upper-normally supplemented by or $1 commonly run in sizes marked with the stand ard lengths and widths of corresponding shoe sizes; but while such “stock” arch-supports are commonly thinned at the forward edge to meet the shoe’s insole as smoothly as possible, and upper surface of which forms part of the normal interior surface of the shoe that gives the lasted depth and internal contouring of a standard size of “stock” shoe; so that, when said dummy is re 40 while the lacing or buttoning arrangement of moved, the foundation of the shoe affords an in- L the shoe’s upper will accommodate considerable variation in the arch-depth of the appliance at its waist without discomfort or making the shoe detachable “dummy” arch-supports or lifts, the v‘35 ternal pocket or depression, throughout its heel and shank portions, wherein a “stock” arch-sup port may be inserted with but little, if any, unde unsightly, the heel portion of the appliance, upon sirable effect on the ?t, the appearance, or the which its proper positioning in the shoe and its cooperative relation to the foot quite largely de pend, is customarily of substantial thickness for comfort of the foot-wear. And, with respect to the manufacture of such shoes," the preferred structure herein set forth lends itself to produc~ requisite stiffness and durability (a thickness of tion by a novel method that insures that the in terior contouring of these special shoes of my about .125 of an inch being a reasonable com mercial average), so that the wearer’s heel is lifted in the shoe materially above the level for which the contouring of the “stock” shoe is in invention, with the dummy arch-support in place, will exactly correspond with “stock” shoes of like tended, with resultant disadvantages. Further advantages of my invention will here inafter become apparent from the following de scription, taken in conjunction with the accom- ;55 Even when “stock” shoes and arch-supports are simultaneously bought, dif?culties in ?tting last-sizes. 2. 2,114,505 panying drawing wherein I have shown one de sirable embodiment of and practice of my inven tion, including various details from which vari ation may be made within the scope of the ap pended claims, but which I have found in practice to give desirable results. In the drawing, Figure 1 is a perspective view showing, in con ventionalized fashion, a shoe cut away in longitu dinal section and having a "dummy” arch-sup port detachably secured in appropriate position therein; the visible part of said dummy having fragments broken away; To give the added depth to the shoe being made, necessary to accommodate the proper dummy arch-support, that particular dummy arch~support which is to constitute a part of the ?nished shoe may be used, or a substantial coun terpart of it; the appropriate “lasting-dummy” being tacked to the last and the shoe being lasted over it. In practice, the amount of surplus upper-ma terial that ordinarily is provided before the excess 10 is trimmed away in the manufacturing operation, is ample to accommodate the deepening of the permanent body of the shoe sufficiently to provide Fig. 2 shows in perspective a shoe-last suitable a dummy-receptive space or pocket A-—Al for use in making the construction shown in Fig. throughout the heel and shank areas of the shoe, 1, in association with a broken-away part of the _ so that, with the dummy in place, the full foot “dummy”; and ' Fig. 3 is a perspective view of a suitable "dum my”, detached. In the drawing, [0 indicates in general the per manent body or foundation of the shoe, conven tionalized in the showing of its sole H, shank l2, heel l3, and upper I4. As a matter of general styling appropriate for use in foot-relief cases, 25 the laced, oxford type herein shown is desirable, with the counter portion I 5 of its upper well sock eted and the top opening l6 of the upper well narrowed at its back, for snug, clinging engage ment with the upper curves of the wearer's heel protuberance. I8 indicates in general an arch-support “dum my”, or removable lift, that normally is secured in place in the shoe body, and the top surfaces of which form part of the normal interior contour ing of the merchantable shoe, giving it interiorly a “stock” shoe shape, substantially duplicating that of regular “stock” shoes of the same make and size. This dummy, I8, simulates a stock arch-support in plan outline, and the depth or thickness of its heel portion l9 and the tapered thinning of its forward edge 20 are in keeping with average practice in the manufacture of well-known stock arch-supports; the waist 2! of the dummy being preferably somewhat thinner than is customary in "stock” arch-supports for the longitudinal arch of the foot and being preferably wholly of leather. A thin body of adhesive, 22, adjacent the forward edge of the dummy, may be used to secure it normally to the insole or sole-lining of the shoe, for easy-enough removal on occasion. The desirable construction of dummy i8 here shown comprises a pre-formed leather top piece 24, suitably arched and skived along the inner side of its waist-portion 2|, and with its heel portion underlain by a reeriforcing layer 25, which here is shown as a short metal heel-plate secured to the top piece by rivets 26. Desirably, the forward end of this plate has its inner corner 60 slightly arched upwardly, as at 21, this "corner hump” tending to prevent forward slipping of the foot in the shoe; to check any tendency of the wearer to rock to the inner side of the foot in walking; and to prevent displacement of the 65 scaphoid—just back of which the hump exerts its slight pressure. For purposes having to do with a desirable pro cedure in making the shoes, the plate 25 is pro vided with a central tacking-opening 28. In manufacture of my improved shoes, it is 70 desirable to use the same lasts 30 on which stock shoes are made; the last shown in Fig. 2 being of ‘conventional style having the usual heel-plate 3| to upset the points of the nails for the shoe 75 heel l3. reception depth A—B, and the last-contours, of the affected area are preserved; and a reduction of height of the shoe-heel I3 is desirably made, to preserve a total height B-C at the rear of the 20 shoe corresponding with the height of stock-shoe for which the naked last is designed. It will be noted that where the identical “dum my” arch-support that is intended to be incor porated in the particular shoe being lasted is utilized as the depth-increasing addendum to the last, its heel-plate 25 serves as a nailing plate in the manufacture of the shoe, to upset the ends of the heel-nails; and that such use of the identical dummy insures that the internal con 30 tours of the completed shoe Will conform with great precision to that of a stock shoe made over the naked last, so that no change from a favored last and size is needed, on a customer’s ?rst re quirement for arch supports. In practice, the wearing of a “stock” arch support in the pocket A—-A1 that is exposed upon removal of the “dummy” arch-support, not only goes very far to avoid discomfort to the wearer and malformation of the shoe, whether worn in I 10 both shoes or only one; but also it reacts to further the effectiveness of the corrective ap pliance itself, particularly by minimizing any tendency of the loosely-inserted stock appliance to work away from proper position in the shoe, ‘ a and by avoiding that slight increase in pitch of the shank of the wearer’s foot with respect to the ground which follows from the use of stock arch-supports in stock shoes. I claim: 1. An arch-corrective shoe adapted to permit the wearing, in either of a pair thereof, of a “stock” arch-support without materially lifting the affected portions of the user’s foot with re spect to the shoe-heel and producing a “limp” effect, comprising a permanent body having an internal pocket in its heel and shank portions and local to the area that is designed to underlie the foot’s width from a line just back of the ball of the foot to the rear of the heel’s undersurface, 60 deepening said portions by a predetermined amount in excess of that required for normal foot-?tting, said pocket depth being throughout the stated area approximately the depth require— ment of a “stock” arch-support that has a thinned _ front edge and a thicker heel-portion; and a “dummy” arch-support normally located in but removable from said pocket and of shape and thickness conforming the shoe’s interior depth and contouring to those which are normal to foot-?tting, “stock” shoes. 2. An arch-corrective shoe adapted, when worn in pairs, to receive in either thereof without ma terially lifting the user’s heel and producing a “limp” effect, a “stock” arch-support, comprising 2,114,505 a. permanent body having an internal depth in its portion receptive of the below-mentioned “dummy” that is greater than required for foot ?tting; and an arch-support “dummy” approxi mating at its front and rear ends the depth of average “stock” arch-supports and plan-con toured to approximately conform to foot-curva tures and to underlie the foot from just back of the ball thereof to the rear of the heel, said 10 “dummy” being normally located in and ?lling said excess-depth space of said shoe body and detachably secured in place in said body as part of the merchantable shoe. 3. An arch-corrective shoe. adapted, when worn 15 in pairs, to receive in either thereof without ma terially lifting the user’s heel and producing a “limp” effect, a “stock” arch-support, comprising a. permanent body having an internal depth in 3 its portion receptive of the below-mentioned “dummy” that is greater than required for foot ?tting; and an arch-support “dummy” approxi mating at its front and rear ends the depth of average “stock” arch-supports and plan-con toured to approximately conform to foot-curva tures and to underlie the foot from just back of the ball thereof to the rear of the heel, saida “dummy” being normally located in and ?lling said excess-depth space of said shoe body and 10 detachably secured in place in said body as part of the merchantable shoe, the forward edge of said “dummy” being skived to merge smoothly into the permanent sole of the shoe and its heel portion being approximately .125 of an inch 15 thick.
