` 3" Claims. This invention relates toshoes of the kindhaving cushioned heel portions. `It hasfor its principal objects to produce a shoe Vhaving a simple and eflicient cushioned heel construction which will be strong and durable and of compact design, and
to provide a simple and economical process of manufacturing such cushioned shoes. The invention consists in the cushioned shoe and in the process hereinafter described and claimed.
In the accompanying drawing, which forms part of this specificationand wherein like symbols refer to like parts wherever they occur,
Fig. 1 is a perspective View of an insole forming part of a shoe embodying my invention,
Fig. 2 is a perspective view of the metallic heel piece employed in the process of manufacturing said shoe,
Fig. 3 is a perspective view of the pad for cushioning theheel of the shoe, j
Fig. 4 is "a vertical longitudinal section through the shoe during its process of manufacture, showing the position occupied by the metal heel piece during the operation of lasting lthe upper to the insole; and l Fig. 5 is a longitudinal sectional view of the finished shoe with the heel cushioning pad therein sole A, an upperB attached thereto, an outsole C attached to the insole, and a cushioning pad D of rubber or other yielding material seated on the heel portion of the insole substantially flush with the inner face thereof. As shown in the drawing, the heel seat l is formed by reducing the thickness of the heel portion of the insole an amount corresponding `substantially to the thickness of the heel pad D. This reduced thickness is brought about preferably by removing the proper amount of material from the inner face of the heel portion of the insole A. The cushioning pad is cemented or otherwise held in its seat.
In the process of manufacturing the above cushioned shoe, the insole A is placed upon a last E with its heel seat I down. A metal plate F, having a shape and thickness corresponding to the shape anddepth, respectively, of the seat in the heel portion of the insole is then interposed between thelast and said seat and the upper is then lasted, in accordance with common practice, to the outer face of said insole, the lasting tacks 2, which secure the rear lasting allowance of the upper to the thin heel portion of the insole, being clinched by striking the plate F. VAfter the lasting operation, the metal plate may be removed and the pad D substituted therefor; or,if desired, said pad may be secured in place after the shoe is nished. The metal plate may be provided with prongs 3 for securing it to the insole, or it may be desirable to secure said plate to the last or make it integral therewith.
As shown in Fig. 5, my shoe comprises an in- (ci. 11e-"142) struction is simple, `economical and compact; it locates the cushioning pad flush with the upper `surface of the insolein position to directly supy port the heel of theWearer;` it permits removal and replacement of the pad without disturbing `the other parts of the shoe and it provides a flush seat for said pad without changing the regularcontour of the insole or outsole. The tacks,
which secure the upper to the heel portion of 10 the insole, are clinched thereon and thus cannot work loose; and the pad serves to preventsaid tacks from coming in contact with the heel of the wearer.

What I claim is:
1. A shoe comprising a, one-piece insole having a thin heel portion forming an open flatbottomed seat that extends from side to side of said insole and to the heel end thereof, and a cushioning member mounted on saidthin heel portion of saidinsole, with its inner face` substantially flush with the `inner face of the thick portion of said insole.
2. The process of making shoes having a cushioningpad in the heel portion thereof which consists in removing the inner surface of the heel portion of an insole to form an open seat that ex- The process employed in making l the shoe is simple and economical. The metal `heel `plate serves as a support for the thin heel tends from side to side of said insole and to the 0 heelend thereof, placing said insole on a last,
interposing` a metal member between said last and 1 the seat in said heel portion of said insole, se` 0 tion of an insole with a depressed seat that ex.
tends from side to side of said heel portion, placing said insole on a last, interposing a metal member between said last and the seat on said insole, lasting an upper to the heel portion of said insole, removing said metal member from said shoe` and then inserting a cushioning member in said seat.
