:BOOT AND LIKE CUSHIONING DEVICE.

Application led September 19, 1922, Serial The space betweenthe insole and sole of boots and the like is usually iilled up with material such as cork or the like, the application of which is troublesome and time wasting, while the filler is liable to c hange .its shape and that of the boot under the -inluence of the heat of the foot.

The object of the present invention is to produce a filler which is free from thev above disadvantages and which has the additional propertyof rendering the boot elastic, comfortable and more durable, and the linventionconsists in the provision of a perforated pad of soft rubber having depressions. which form a narrow, raised ridge around each perforation, the pad being provided with bevelled edges so that it can be readily litted into the boot like the ordinary1 ller and with the ridges turned towards the insole.

Fig. l of the accompanying drawings represents a longitudinal section ofthe improved boot,

Fig. 2, a cross-section on the line A-B of Fig. l, and

Fig. 3, a plan of the filler.

The insole l of the boot has a down-turned edge 2, with which it-is connected to the upper 3, to the toe stitlener 4, to the lining 5 and to the edging iframeA 6 in the usual manner. In the space formed-between the insole, its down-turned edges 2 and the outer sole 7 a filler 8 is introduced which is composed of a pad made of soft rubber 35 and shaped in conformity with the sole.

The pad is formed with a plurality of per- No. 589,132, and in Germany June 23, 1922.

forations 10 the edges 11 of which are raised so as to form depressions 1 2 between them. These depressions are turned towards the insole so as to enable the latter to present to the foot a highly elastic tread.

The edges m' otthe filler are bevelled off for connection to the soles and slope away 4 from the ridgcd, elastic portion so as'to leave the latter in a projecting position in the middle of the ller. By this arrangement the elasticity of the filler will be utilized to its full advantage.

i I ana-aware that ridged, elastic pads have already been made use of as ventilatin elements in boots and the like and also t at a pad having perforations and ridges ar ranged in the same manner `as in my ller, has been designed for use, with downwardly directed ridges, as an inside, water-proof, elastic sole,l and I Wish it to be understood that my claim is only confined to the use of a. pad of this type -in place of the lordinary iiller and in place of a known type of plain, perforated rubber ller.

I claim:

In boots and the like, the' combination with an outer sole andan insole, of a filler composed of a perforated pad of soft rubber provided with depressions which 4form 65 a narrow, raised ridge around each perforation,'the edge of the pad being bevelled off so as to slope away from said rid ed portion, said filling padbeing arrange in the space between the soles with theridges i turned towards the insole.
