SHOE

Filed April 3, 1943 INVENTOR: CALVIN G. hmus BY A TTORNEY Patented May 9, 1944 3 Claims.

My invention hasrelation to improvements in, shoes and it consists in the novel features of construction more fully set forth in the specifi cation and ,pointed out in the claims.

The invention is primarily directed to shoe 5 construction having a vcounter which will not break down and cause the shoe to lose its shape. In accomplishing this object I form the counter integrally with the insole, made 01' a flexible plastic material, with a rigid arch and counter in support molded into the plastic.

A further object is to employ a plastic material for the combined counter and insole to which rubber may be vulcanized or to which the outsole may be sewed, cemented or nailed in as desired. I do not specify any particular plasticmaterial as there are a number of such materials that may be utilized. The essential properties of the material are that it be capable of being molded so the metallic arch support may 20 be imbedded in it, and that it possess the necessary flexibility-for a shoe insole, and at the same time lend itself to fabrication into a shoe.

These objects will be better apparent from a detailed description of the invention in connec- 2i! tion with the accompanying drawing, in which:

Figure 1 is a side elevation of a typical street shoe with parts broken away to show my improved counter and insole embodied therein;

Fig. 2 is a detached view of my combined counter -and insole with a metallic arch support molded into it; Fig. 3 is a section taken on the horizontal plane indicated by the line 3-3 on Figure 2; Fig. 4 is a vertical section taken on the line H on Figure l; and Figure 5 is a perspective view- 35 of the arch and counter support. v

Referring to the drawing, S represents a standard type of walking shoe in which the insole I is formed of a flexible plastic material and I has the counter 2 formed integrally with it. in-

stead or separately as in the usual shoe construction.

v Calvin C. Klaus, Highland, Ill. Application April v3, 1943, Serial No. 481,669

The insole may be of some artificial rubber composition, or a combination of rubber and fabric, or a plastic that has sufficient stifiness to form a durable counter, and, at the same time, flexibility for walking comfort. In order to give support to the foot, an arch support 3 is molded into the body of insole, said support 3 having a flange 4 extending around the heel part 5 of the counter. The flange, 4' has an extension 6 to serve as a support for the instep portion I of the shoe.

An opening 8 is formed in the heel part 9 of the arch support 3 to permit nails ill to be driven through the heel lift through the insole (Fig.

4). 01 course, the plastic material of the counter and insole will be pressed into the opening 8 to further integrate the arch support with the plastic. 7

As stated above the shoe may have a rubber outsole, in which case the plastic insole and 4 counter should preferably be of a material thatcan be vulcanized to the rubber sole.

Having described my invention, I claim: 1. A shoe having an'insole formed of -aplastic material, said insole having a counter formed integral therewith, and a; rigid arch support molded into the insole, said arch support having a flange supporting the counter.

2. A shoe having an insole formed of a plastic resilient material and a rigid arch .support' molded into the insole, said arch support having an opening in the heel part thereof through which the plastic may flow.

3. A shoe insole formed of resilient plastic material having a counter formed. integrally therewith, and a rigid arch support molded into said insole, said arch support having a flange extending into the counter part of the insole.
