Specification of Letters Patent. 7 Pitlliitdq 514 Application filed July's, ieie. jsaei No, 309,368.

To all whom it may concern: I

Be it known that I, ARENT AUGEs-TAD, citizen of Norway, residing at Marka Brandbu Station, Hadeland, Norway, have invented new and useful Improvements in Inlay-Soles for the Prevention'of the Development of Galls, of which the following is a specification,

The present invention relates to unprovements in inlay soles for boots or shoes, the object of the inventionbeing to provide a device of this character which will prevent the chafing of the feet of the wearer and thereby avoid the formation of galls or blisters.

The drawing accompanying and forming part of this specification illustrates in side elevation, partly in section, an embodiment of the invention.

It stands to reason that boots which are manufactured wholesale very seldom fit the foot so exactly that when the wearer is walking they can follow the movements of the foot with accuracy. This is especially the case when heavy laced boots such as are used by workmen and soldiers are worn.

With such boots it is impossible to prevent the foot-under its efforts to bend the sole and the bootfrom moving to a certain extent within the boot or shoe, the result of which movement is that the heel of the foot rubs against the heel of the boot, thereby causing the formation of blisters.

The object of the present inventlon is to provide a device by means of which the in-' evitable movement of the foot with relation to the boot shall not produce any injury or discomfort to the wearer. This is accomplished by fixing the position of the foot within the boot so that a predetermined dis tance is maintained between the heel and toe of the foot and the heel and toe of the boot, whereby the foot may move within the boot without chafing. To obtain this result a suitable intermediate part is placed between the foot and the boot, consisting of a double inlay sole, one part of which is adapted-exactly to fit the bottom of the boot or shoe and the other part of which comprises means for securing it to the foot and preferably has the form,0f ,a, heel-cap with fastening.

belts or laces. 7

.Referring to theldrawing, 1 is the lower by-sole, which is made of a stiff material such for instance as zinc or hard, stiff leather. To the toe seam?) is situated at a predetermined distance from the tip of'the sole in 'orderto render the cutting of the edge possible, which is necessary in order tov adjust the by-sole exactly to the bottom of *the shoe. In order to make it possible during walking to move the sole 2 freely with relation to the by-sole, the'latter extends somewhat, beyond the rear end of the sole 2-. Adjacent to the rear end of the sole 2 is secured a heel cap & of suitable height to give the necessary support to the foot during walking. This heel cap is provided with lengthened side portions 5 which embrace the foot and may be P o this sol the 'fieeilble $016 2 isfastened. The connectin connected to each other bymeans of strings or laces 6 over the ankle.

It will be understood that the by-sole i when correctly cut will lie immovable in the boot just as if it was fastened to the bottom I of such boot'o'r shoe, although it may be taken out and inserted into another shoe of suitable length. If, for instance, the length of the foot is 26' centimeters the by-sole should have a length of approximately centimeters and should'extend 3 centimeters I to the front of and 1 centimeter to the rear of the foot; The sole will then fit into a shoe of the proper size for such afoot.

- In the use of a device such as above described thefoot will occupy a fixed position with relation to the shoe, so that neither toe nor heel will come into contact with it, whereby the formation of blisters is prevented while at the; same time the natural mobility of the foot'is maintained.

The foot may, of course, move inside of the shoe by reason. of its anatomical natural joint connections without the use of an intermediate part between the foot and the shoe 1 as above'described, but this mobility is combined with chafing and unnecessary straining of the foot, whereas by the use of this improved device the foot retains its free mobility without being subject to such straining or chafing, since it effects the bending of only the flexible sole which is connected to the foot, the by-sole and the shoe not follow ing the movementsof the foot. This involves alsoan easier Walk than without the inlay device described/ It is evident that the details of construc tion of the inlay device'may-be varied with out departing fromthe spirit and scope of A If 7 10 Eric;

- the present invention. Forinstancepthe flexible sole may comprise meansfor the connection between thefoot and the heel cap described and shown.

Having thus described my invention, what I claim is: 7

1. An inlay device for shoes, comprising a flexible sole, a comparativelyrigid sole connected tosaid flexible sole at the toe tip of the latter, and means for fastening said flexible sole to the foot of the wearer.

' QJAn'inlay device'as set forth in claim 1, the flexible sole being provided with aheel cap. v 1

3. An inlay'device as set forth in claim 2, the heel cap being provided with elongated side parts adapted to be connected together over the ankle of the wearer.

4. An inlay device as set forth in claim 1, the flexible sole being connected to the rigid sole at a predetermined distance fromthe toe tip of the latter.

5. An inlay device as setforth in claim 1, the heel portion of the rigid sole extending behind the heel portion of the flexible sole.

6. An inlay device as set forth in claim 1,.

the rigid sole extending beyond the flexible sole at both ends thereof.

7. An inlay device as set forth in claim 1, the flexible sole being provided with a heel cap having elongated side portions adapted to be connected'together over the ankle of the wearer and the rigid sole extending beyond the flexiblesole at both ends thereof.

In testimony whereof I have signed my name to this specification.
