r a 40mins. (01 36- 76) M similar reference characters designate corre- This invention appertains to footwear, and more particularly to shoes, which are adapted to' be worn by nurses and other personswhose calling necessitates their being on their feet on greater part of their working ]'101 1: :5 'v It has been proposed to provide a wedge-shaped pad of cushion material (such as sponge orother rubber) in the-sole of the'shoe at theheel to arches' of the wearer. Suchshoes are admirable for the purpose intended, 'but' the same are'open to certain objections, such as undue wear 'onthe heel face and the difficulty contingent'with the repair of the shoes when such wear occurs.-

It i's, therefore,one of the salient objects of my invention to provide a shoe of the above character so formed as' to receive a rubberwear' lift or heel which can be readily replaced when worn.

Another important object of my invention is to provide a shoe having a rubber cushioned pad at its heel provided with an offset in its lower face to receive a removable wear heel lift, the offset portion permitting the wear heel lift to extend flush with'and from a continuation of the bottom of the shoe sole.

A further object of my invention is the provision of novel means for forming the heel seat in the heel cushion for receiving the replaceable wear heel lift, and novel means for reenforcing and strengthening the seat.

A still further object of my invention is to provide a shoe of the above character, which will be durable and efllcient in use, one that will be simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawing, in which:

Figure 1 is a fragmentary side elevation of a shoe constructed in accordance with my invention;

Figure 2 is a fragmentary longitudinal section through the improved shoe;

Figure 3 is a fragmentary bottom plan view of the improved shoe with parts thereof broken away and in section to illustrate structural details;

Figure 4 is a. detail section illustrating a modified form of my invention.

Referring to the drawing in detail, wherein sole l terminates at the heel of :theshoe, for a purpose which will be laterset forth. a 1:

Interposed between the insole 5 andthe wear sole 1 is a cushion pad 8,which can beforiiied of sponge or anyotherzdesired type of rubber; As clearly shown in Figure 2 of .the drawing, the

cushion-pad 8 extends beyond the wear sole"! and covers the entire area of the heel; Thepad also extends over .the archof'ashoe to form a resilient support for the archof the wearer. If preferred, the cushion pad can have its sides covered by flexible leatheror fabric 9, which can either be secured inplace by theuse of an adhesive'or bystitching; i

In accordance with my invention, the cushion pad 8 at the heel has its lower face oflfset as at 10 to provide a cavity or seat for a removable heel or wear lift II. This lift or wear heel ll can be formed from rubber, if so desired. The lower face of the cavity or heel seat has secured thereto a sheet of fabric or leather l2 which is firmly secured to the cushion pad by glue or other desired type of adhesive.

In order to form an adequate support for the rubber wear heel II a thin metallic plate I3 is provided. This plate l3 covers substantially the entire surface of the heel seat and the forward edge thereof has formed thereon an offset forwardly directed sharpened, pointed penetrating prong l4. This prong I4 is inserted directly in the cushion pad 8 at the arch, and the plate itself is connected with the sheet of fabric or leather I2 by rivets or in any other preferred manner.

The wear heel H can take the form of an ordinary rubber heel and the same is placed in the cavity or heel seat with its forward edge in abutting relation to the front wall of the cavity or seat formed in the cushion, and with the rear edge of the wear sole 1. Suitable fastening elements, such as nails l5, are utilized for holding the rubber-heel in place. These nails l5 are driven through the heel and through the plate I; and sheet l2 into the cushion. Obviously, when wear takes place on the heel l I, the same can be easily removed, and a new heel placed in position.

The wear heel or lift l I can be secured in place i These prongs have formed thereonoppositelydirected heads II. The metallic plate ll, at spaced points, can be provided with openings or sockets I! for receiving the headed prongs. In

this form of the invention, the heads I8 of the prongs H are first inserted in the openings in the plate If, after which the rear end of the heel is swung upwardly, and the heads of the rear prongs are snapped into the openings. To facilitate the insertion of'the rear prongs, the faces thereof can be bevelled or bent on an angle, as indicated by the reference. character 20; When the heel becomes worn, it is merely necessary to utilize an instrument to force "the heads of therearmost'prongs out of the uppermost.

Changes in details may be made withoutdeparting from the scope of my invention, but what I claim as new is: v v

' l'. A shoe comprising an uppenan insole, and an outsole, a pad of-cushioned material interposed between the insole and the outsole at the heel and arch of the shoe, the'wear sole terminating in rear ofthe arch-and in front of the an outsole, a pad of cushioned material interposed between the insole and the outsole at the heel and arch of the shoe, the wear sole terminating in rear of the arch and in front of the heel, the cushion pad having its lower face oi!- set at the heel, and a removable wear heel secured in said offset, the lower face of the wear heel being flush with and forming a continuation of the outer face of the outer sole.

3. A shoe comprising an upper, an insole, an outsole, said outsole terminating at the rear part of the arch and in font of the heel, a pad of cushioning material covering the heel portion of the insole and interposed between the insole and the outer sole at the arch of the shoe, the heel portion of the cushion pad having its lower face provided with, an offset, a strengthening plate secured .to the lower face of the oifset of the cushion pad and having its forward edge pro-- vided with a forwardly directed offset tongue anchored in the arch of the cushion, a removable wear heel fitted in the offset of the cushion pad against the plate, and fastening elements extending, through the wear heel, through the plate, and into the cushioning pad, the lower face of the wear heel being flush with the lower face ofthe. sole.

4, A shoe comprising an upper, an insole, an outsole, a pad of cushioning material interposed between the insole and the outsole at the heel and arch of the shoe, the wear sole terminating in rear of the arch, and in front of the heel, a strengthening plate secured to the lower face of the cushioning-pad having sockets therein, a removable wear heel, and a plate embedded in said wear heel, and resilientheaded prongsv on the plate extending beyond the upper face of the heel received in said sockets.
