In cementing layer I8 to layer I0 care should be exercised to position the former so that the fork of the bifurcation and the inner edges of legs 32 and 34 are contiguous with the margin of the metatarsal button, and the rest of layer I8 centered with respect to the margins .of layer It) so that the margins of the latter overlap the margins of the former. Main arch piece I5, except for the forward end 36 thereof, is

now' cemented to layer I8 somewhat along the inner sideof this layer and in the region which is below the longitudinal arch of the foot, with the forward end overlapping the rear portion 38 of the metatarsal pad.A End 36 is then ce- Y flexible edge, designated as 42,*extends the rest of the way around the arch support and because of the flexibility of this edge the arch support conforms readily to anystyle of shoe.

Itis manifest from the foregoing that at the juncture 44 of the fork of the bifurcation of layer I8 and the edge of the metatarsal pad there is providedfa hinge-like joint which enables the arch support to readilyfit the shoe and allows the longitudinal arch of the support to raise when the weight of the wearer is on thesupport. The end 36 of the main arch support piece I6 bridges the trough'formed by the contiguous skived` edges of the cushioningv layer I8 and the metatarsal pad, thereby levelling out this depression' and at the same time strengthening the hinge-like joint. A*

The rubber cushioning layer I8" functions as a shock absorber and provides support and balance to the cuboid region of the foot. The combinationiof this 'layer with Athe main arch support piece I6 and themetatarsal pad, in the manner described, gives'the human foot arch not only a' brace-like support, vbut'a more natural, flexible support and stren-gthener which enables the wearer to wear the supports without suffering the usual discomfort of thek breaking in.

While I have described myinvention in connection with the drawing illustrating a preferred embodiment, it is to be understood that it is not to be construedas limited to this embodiment or to the details thereof since many changes in these details and in the nature of the materials used in making my arch support may be varied without departing' from the scope of the invention defined inthe appended claims. for example, the cushioning layer and the metatarsal pad may be formed as a single unitary structure. Neither is my invention to be limited to the method Iof making the arch support as described herein since changes in this method maybe readily made as'will be evident to a skilled worker in the art; f Y
