acitizen-of the United States, residing at .Des Moines, in the county of Polk and State .oi'lowa, have invented 'a'certain new and useful Insole for Shoes or? the like, of when the following visa specification.
I-The ohjectof my invention is to provide tionfixed thereto,- the parts being simple,
of athletic types-which are provided with rubber soles.
- Still a further object is to provide under the heel portion'of the foot-e resilient pad orstrip of material which, is provided with oval-shaped grooves extended. only. part way through said pad for permitting the resilient portion to be spread or moved to J position Where it will conform to-the underside of the heel of the foot. o
Still another object is .to provide heads which are formed'adjacent' to the edgesofthe grooves-in the resilient'material, which ribs are ada'pted'to co-ect or rest against the inner surface of the sole, of a shoe for preventing the possibleslipping of vthe insole within; the sl1o e,iorfrom having it crowd Ctowardsfthe toe of the shoe.
1 Still another object is'to provide an issole of substantially the same shape as-the sole of the shoe, the resilient portion, however, being provided only under the heel portion ofthe insole, and being held in 'position bymeans of the remainder of the insole, which is preferably made'of a tough strip of: fiaterial such as leather or cloth.
A leather insole or strip of material; when it is used'with an athletic shoeserves'asa non-conductor of the heet which is usually exgerienced with shoes having rubber soles.
till another object'is to provide the resilient'portion of the insole directly helowv a The groovesl i permit the resilient pad-13 ,the heel of the iootso that .it may serve as a-heel or raised portion When. it. is: used in 'a'nathletio 'shoeg and -at thesame time serve as a cushion for preifenting jars and shocks dueiofialkingrunning or jumping, or any other exercise. a
"With these and other objects in View my invention consists in the, construction,
errangement and combination of the various parts of my dew icm-whereby the; objects" contemplated are attained, as hereinafter 'Applieetion fiie i' my 25,-

,In the accompanying 'dratvings have used the reference numeral 10 to indicate m cs; pointed out imy on the line of FigureQ through the on ordinary athleticshoe; which is provided I :with a sole 11 preferably of rubber. I
It Will'be understood that in most athletic shoes practically no heel or raised portion for a heel is provided.
A My improved sole comp'rises-afstrip of trough material 12 preferably of leather and substantially the outline of a shoe sole. The strip of material 12 maybe said to c'ontain two parts, a heel portion A .and a sole portionB. 'f h Fixed to the underside of the heel portion A of the strip of material 12' is. a resilient pad or-ciishion 13, preferably-of rubber." The pad of resilient material 13-" is tapered from itsforwaid end slightly so as to pm, vide an. inclined portion between the heel,
-Th'e pad -13-is provided 'with'a plurality of grooves 14 which; are oval-shaped in cute line, and spaoed'one Within another, as clearly illustrated in Figure2'of the draw-. ings; Each of the grooves 14: have thein-v set. forth;
to be easily compressed to conform to-the edges proyided Witha loead, 15, the purp0s&,=-
of .Which will be- .hereinaft ern ore fully?" outline of theheel of the foot and (at. the
same time serves as a cushion for-any sudden 16 between the'gro'oves 14 will be spread or caused to 'fill'the gIQOVGSfll: when any presever, assoon as the pressure is releasedthe jar or shock; The portionof the material" sure isapplied upon the resilient pad.- 'Howpartsrwill'ret urn to their; normal position and thus serve esa cushion.)
The beads which project downwardly beyond the lower surface of the main body portion of the pad 13 rest upon the shoe sole and thusprevent the easy slipping of the entire-insole within'the shoe orthe heel portion from crowding towards the toe and at,
the same time gives additional flexibility to the pad '13.
By providing the pad 18 below the heel portion A. of the strip of material 12- it not only serves as. a cushion forthe preventing of any shocks or jars, but it also normally serves as a heel "for an athletic shbe.
The pad 13 is arranged so'that its edge, 'is flush with the edge of the heel portion of the strip-of material 12 so as to prevent its I edge being bent downwardly due to the pressure of the foot. thereon. The pad 13 serves to make the cushion efiectfgreatest whereit' is 'most desired, that is, where the surface of the persons heelrests. The spread of the contour of the foot.
The arrangementof the pad 'lilllush with ,the heel portion A of the strip of material- 12 prevents such an undesired effect as hereinbetore described.
Another advantage is the arrangement of the stripv o'fleatherwvhich covers the entire shoe sole and serves as a non'conductor of heat in the athletic shoe. Another advantage of my lnsole and resilient cushion is that a heel is formed and thus the breaking down of a persons arch due to the no-heel't vpe of shoes is substantially eliminated. I
From the construction of the parts just described it will bescen that myinsole is very simple, can easily he slipped into or out of the shoe, and when used will be very com-' fortablc. It will be understood that my type of insole may be placed in-the shoe at the time of manufacture of the shoe'and per;
inanently secured therein. v I
Some changes may be made in the construction and arrangement of the parts of my insole without depaiting from the real spirit and purpose of my invention, and it is my intention to cover by my claim, any mochfied forms ofistruoture' or use of mechanical equivalents, which may be reasonably ineluded within its scope.
I claim as my invention;
An insole for shoes of substantially the outline of a shoe comprising a strip-of tough material, divided into two portions, a heel portion" and a sole portion and a resilient strip of -niaterial of substantially the same outline as said heel'portion secured to the underside ot'said strip of tough material,
said resilient strip of material'having a plurahty or oval shaped grooves-therein, said oval shaped grooves being spaced one within the other and being substantially the shape'of an inverted U in cross section, the
materialbetween eachof the said last grooves being providedjwith comparatively shallow] formed on the edges of said first groove, the
parts being so arrangetl thz'it the inaterial between said grooves will be spreadoutand forced into said grooves when under pressure,
thus giving a cushioning eitect to any sudd n pressure applied upon the heel portion of said insole all for the purposcsstated. Des Mtines, Iowa, July 18th, 1921.
