INsoLE non sirons Application sied september 18,1929.; serial No. 393,526. l

v This invention relates to insoles for shoes and the like', andmore particularly to insoles.

of the type adapted to be inserted loosely in the shoe to aiford a better foot engaging sur-Y 5 face than that usually provided in the shoe.

he primary object ofthe invention is toV present a comfortable, smooth, ventilated surface for the foot. Still another Objectis to enable the insole to insulate the foot 20 against excessive heat or cold, so that the feet can be cool in hot `weather and Warm in cold weather.

A further object is to enable the insole to be moisture proof, so that the foot can be kept 25 dry even though the sole of the shoe may be Wet; and also, to enable the insole to prevent perspiration of the foot and odor therefrom.

A still further object is to improve the construction of insoles generally, so as to make them long Wearing, and to enable the same to be produced at small expense.

Other objects and advantages of the invention will be hereinafter specifically pointed r out, or will become apparent, as the specification proceeds.

- With the above indicated objects in view,

the invention resides in certain novel con.-L

trating. the conformation feature to prevent buckling or cracking. 3 y I f filhe insole 10`in this instance comprises a thin., fianet-rip 11, shaped to conform to the outline of thev shoe sole.'y This strip 11 is formed as a flexible unit and preferably includes a top layer 12 and a bottom layer 13. 'lfhetop layer in this instance consistsof a material which is impervious and at the same time presents a smooth, glossy surface. have found celluloidto be very satisfactory for this purpose, .but any y'material having substantially the same characteristics may be used. Thebottom layer 13 in this instance, consists of. a fabric material though I may use fibre or'any reasonably-strong material, or Celluloid-like material atfboth upper and under layers, With equal satisfaction. y The top and bottom layers are permanently united sothat'thetwo layers constitute an integral unit. n Y y To provide fory ventilation of theinsole, I lay out aplurality of series of small relatively closelyspaced'.apertures l1li, extending the same longitudinally of the insole in a central line 15, with lines 16y andv17 to the left and right of the central line, respectively. `These ventilating apertures enable thefeet to resist the developmentof perspiration, with conse- .quentvodor and theyalso tend to help the dissipationof heat developed from friction during locomotion.

` The construction of the insole enables the saine to withstand lcracking along the body of fthe insole; yetl the ,insole is vflexible and adaptedtolconformto the depressions in the inner leather sole of the shoe which are usually Vformed .by the foot after av short use. 1n order to prevent cracking or curling of the louter edges of the insole'at the'end of the heel yportion and at the sides of the toe portion, which v,usually[takes place due to the fact that depression 'ofthe leather sole of the shoe occursl at these points, Iprovide a plurality of rounded notches 18 aroundthe outer Aedge 19 of the insole.l -l'nithis instance, I form aV series of three such notches at the end ofthe heel portion of the insole, as seen at 203e. second series 21" at the left sideVv of the toe portion, and a third series 22 atrthe curl, dueto the depression of the leather shoe sole at the sides of the foot, the sides'of: the open portion 23 meet each other to close up the open portion 23, thus-presenting an' unbroken outer edge 19as seen inrFigure 3. Thus'there arenojcracls formed, nor canithe edge ofthe insole bulge' up to injure the foot or its covering. I h'avefoundthat: three Y notches inV 'each series, as illustrated herein,

accomplish the abovet described purposes satisfactorily. ina majority of cases; but a greater or less numher'ofi notches may be provided depending-ion' thel size of the insole. I Y y Theinsole constructed as above affords a very vcomfortalole hearing for the foot', in

Vany temperature or weathercondition, and

its therapeutic ar'lvantages'render it highly desirable for use by persons obligedA to be on their feet a large part of the'day.l

The hereinbefore described, constructions admit of considerable Inodiiications'without departing from theV invention; therefore, I

do not `wislito he limited to the precise ar rangements shown and described, which are, as aforesaid,A by way of illustration merely. In` other words,y the scope ofprotection" conf templatedis' to he taken' solely' fromk the appended claims, interpreted as broadly" as vis consistent with the prior art.
