6 Claims. (Cl. Sii- 37) This invention relates to improvements in cushion constructions for shoes. The invention has particular application to the heel portions of shoes having heels fastened from the inside, but is also of more general application.

It is the object of the invention to provide a novel and improved construction which not only accommodates an additional ply of cushion material at the heel but, in addition, stiffens the shoe at the point at which the heel is connected.

In the past the recess necessary for the accommodation of special cushion plies has been made either by inserting a semi-annular piece ol" material as a lift or by cutting, punching, or skiving away portions of the sole material to provide the necessary opening. The present invention contemplates the compression of the sole material whereby the necessary recess is provided without the removal of any material from its thickness. In addition, it may, if desired, be bodily offset in a recess punched or molded in the ber reinforcing ply I I, as is clearly shown in Fig. l. The compression and offset not only provide a recess into which the extra cushion ply I'I can be introduced, but it also greatly stifens and rigidies the leather. Consequently the screw I3 and nails I9 used to anchor the heel nd a more rm seat in the portions of the insole which have been rigidied by the compression. The heads of the fastening devices, whether screws, nails, or both, will have additional cushioning under the added cushion ply II, and are thus renderedV entirely imperceptible to the wearers foot.

In the Fig. 2 construction the heel 'I is slightly countersunk at so that the head of the screw I8 can more adequately be seated in the portion of the insole Iii which has been thinned and 20 the sole, the compressed material being greatly rigidiiied by compression. The fiber stiifener II 20 hardened and rigidified to provide a better anhas been omitted in this construction, which is chorage for screws or nails used in the attach otherwise identical with that of Fig. 1. ment of the heel, and the heads of such screws In the Fig. 3 construction the fiber stifener or nails being covered by the cushion inserted III is used but has not been subjected to comin the recess thus made by compression. pression.

3. In a shoe, the combination with a heel having a countersunk top portion, of a sole ply superposed on the heel and having an area above said heel compacted and densified under compression to rigidify the sole material in said area and to provide a recess, fastening means having a head portion seated on the compacted area at the bottom of the recess and extending through said countersunk portion of said heel into engagement in the heel, said rigidied sole portion being deformed into the countersunk portion of the heel, and a cushion ply positioned in said recess and covering said anchorage means.

4. In a shoe, the combination with sole material having a predetermined area compacted and densified under compression to provide a recess, of an anchorage device extending through said sole material in its compacted area and having a head positioned in abutment with said sole material in said recess, a cushion ply tted in said recess over said head, a larger cushion ply applied across said sole material and the cushion ply aforesaid, and a nishing ply superposed on said larger cushion ply.

5. In a shoe, the combination with a heel, of

a sole portion disposed above the heel and having a limited area so compacted under pressure as to be densied and reduced in thickness and anchorage means extending through said limited area downwardly into the heel and having a head portion engaging the upper surface of the densified area, a ply of sole material having an aperture registering with said area, and a cushion of greater thickness than said ply filling said aperture and the recess formed by the densical'ied area, a ply of sole material having an aperf ture registering with said area, a cushion of greater' thickness than said ply llng said aperture and the recess formed by the densication of said area, said cushion covering the head of said anchorage means, a second cushion substantially covering the heel portion of said sole and also covering said first mentioned cushion, and a liner over said second cushion.
