An object of the invention is the provision of an insole for shoes having a yielding, impressible body.

A further object of the invention is the provision of an insole which is exible to 'a high degree.

Another object of the invention is the provision of an insole having a margin of normal thickness 10 and a relatively thin flexible body.

A still further object of the invention is the provision of an improved insole which may be used in the manufacture of various Well known methods of shoe construction.

will become `apparent as the description progresses. j 4. In the accompanying drawing forming a part of this speciiicationand in which like reference ing parts throughout the samez.

sequently, fairly thick, strong and somewhat rigid.-

In forming my improved insole the body is cut in the desired shape from the butt leather and the lip I0 formed on the bottom face at the margin,

that is, at a position set inwardly from the side edge of the leather and projectingl at a right angle to the body. VThe lip formation may be eliminated from the heel part ofthe leather and 55 may consitute a at marginal portion, indicated -Other objectsand advantages of the invention'.A

characters are employed to designate correspond Figure2 is a` transverse section taken on the.

Referring to Figures 1 to 4 inclusive, .wherein-v at I I. Prior to or subsequent to the formation of the lip III) on the insole the bottom -face of thethe insole and the outsole. Inasmuch as the. main Thus, the insole embodies a relatively body portion of 'the insole is quite thin, the

leather will be q-lte yielding and impressible upon the soft yielding cushion I5 to greatly enhance the comfort of the shoe. Furthermore, the cutting or scraping away of the body leather; forming a hollowin the bottom face, renders the insole flexible to a much greater degree so that the completed shoe will also be of greater flexibility. In order to 'further enhance the comfort of the insole and cushioning. construction, I contemplate providing a plurality of apertures I6 -in the body at the toe, so that compression of the assembled laminated sole will enable the air to escape between the insole body and the outsole e through the vent openings and obviate the ,for-

mation of air po'ck'ets or wrinkles.

A modified form of -the insole, shown at Figures 5, 6 and 'Lembodies an insole having a. main body portion hollowed out by a. scraping tool or the like forming a hollow I8 inthe top face so that the insole comprises va relatively thick flat marginal. portion I9 and a. body portion 20 of decreased thickness providing ayielding, flexible body construction. 'Ihis form of insole is particularly adaptable for the constructionof McKay shoes, as shown at Figure 7, or other shoes, such as Compo, nailed or wherein the securing means extend through the sole, upper and insole.

\ Another modification of the insole, shown at Figure 8, comprises an insole leather forme/d oi normal or conventional thickness having the'bottom face hollowed out at the front, as indicated at 22, providing a. relatively thin flexible front body portion having av thicker marginal portion 23 of normal thickness. At the rear or heel portion the insole is scraped or otherwisetreated to "'form a hollow 24 in the top face, providing a thin rear bodyportion surrounded by a relatively thick marginal portion 25. 'I'his insole construction enables the assemblyof a cushion bealso enables the positioning of padding or cushf ioning material directlyfon` the top/face of the heel. n '1 It is to be understood that the .forms of my invention herein shown and described are tovbe taken as preferred examples ofthe same and that various changes as to the shape, size and arrangement of vparts may be resorted to without`departing from the spirit of the invention or the scope of the subjoined claims. v

Having thus described my invention, I claim:

1. An inlaid insole having a central body portion entirelyr hollowed down to a uniform thickness a fraction only of the margin-which issolid material of usual thickness and of a width sufface adjacentl the edge. the body portion denned within said lip being uniformly hollowed out to practically the top grain of the leather to form a thin flexible body portion, Ventilating means provided at the extreme toe end o! the insole, and

a fiat padding of resilient porous material inlaid in the hollowed out portion to restore the same to its original thickness.

e 3.l A ventilated impressible insole, said insole having a solid margin o1' a thickness and width such as are considered necessary and'normal in shoes for which the insole is intended, the central body portion comprised within the margin being `uniformly hollowed out to practically a. fraction only of the margin thickness, the sides of said hollowed out portion being well denned and vertical', the hollowed body portion further having
