' i ciohn. (ci. ses-'11) The object of this" invention is to provide nt a minimum cost, a shoe-element including an. inner sole and a cushion associated therewith 'adapted vto yieldingly support the longitudinal arch of a human foot.
Of the accompanying dravwing forming a part of this specification.-
Figure 1 is a top plan view of a shoe element embodying the invention looking toward the foot bearing side of the inner sole.
Figure 2 is a section on line 2-2 of Figure`l.
'Figure '3 is a section on line 5 3 of Figure 1.
Figure 4 is a sectional view showing the ele` ment incorporated ina shoe.

The same reference characters indicate the same parts in all of the gures. The drawing shows a leather inner sole which in this instance is adapted for use in a welt shoe, although it may be otherwise adapted.
'I'he sole has a concave edge portion I3 at the inner edge of its shank and nn incision, tie closed end of which is shown at Il.Y Said incision extends from the h'eel endforward to the ball portion of the sole, and divides the' heel and shank portions into a thin top layer I5 and-'a 35 of the concave edge portion I3, and'each being integral with the fore part of the sole.
'The` sole is provided with an elastic oblong edgeportions- I3 of the top and bottom layers.l
l .The inner side of the cushion is cemented to the top surface of the bottom layer I6 with thecon- 55 The top layer I5 cemented top surface Figure 5 is a perspective view of the sole and thicker bottom layer I6. each layer'having a p'art cushion I1 preferably of sponge rubber whichis thicker than the top layer I5, and has a concaveA inner edge shaped to conform to the concave" cave edgesof said layers and cushion coincidingof the cushion and to portions I8 and I9 of the bottomv layer not covered by the cushion.
The top `layer has three narrow flexible portions 20, 2| and 22, projecting from the cushion and attached to portions of the bottom layer 5x spaced from the cushion`,the portion 20 extending-.along the forward end oi' the cushion, the portion 2| along the outer longitudinal edge, and the portion 22 along the rear end. Said exible portions constitute exible connections 4between'lo the portion of the top layer which is cemented to the cushion, andthe lportions of said layer which are cementedto the bottom-layer. The connections 20,' 2| and 22are backed by air spaces so that they form portions of the foot- 5 .v it, to the transverse inclination of the foot soleA at the shank portion of the foot, as shown by Figure '1.
It will now be seen that the cushion'is rmly Ysecured to the sole -by thecement connection between its inner side and the bottom layer IB the eemenioonneetion between its top side and 25 the top layer I5, the cement connection between lportions of the top layer and the exposed surfaces I8 and I8 of the bottoinlayer, and the inclined exible portions 20, 2| and 2 2, of the top layer. 4Iclaimr A longitudinal arch supporting shoe element -composed' of an inner solesplit from its heel end into its ball portion, the split portion including a relatively thick bottomlayer and -a, thinner top 35 layer, said layers having concave inner edge por-f tions at the shank, and an elastic cushion interposed between, and cemented .to, the inner portions of said layers and having"a concave inner edge coinciding and flushy with the concave edge 40 portions of the layers, the cushion being oblong and narrower than the inner sole, and having a. longitudinal outer edge spaced from the outer \edge of the inner sole, .and a transverselyfextending forward end which is the widest portion of the cushion, the top layer being'cemenjsed -to the top-surface of` the cushion and to portions of the bottom layer not covered by the cushion. the top layer having three narrow exible por- -tions projecting from the cushion. and attached to portions of the bottom layer spacedfrom the cushion, one of the portions extendingalcfng the forward end of the cushion, another portion along the outer longitudinal edge, and-the third portion along the rear end of the cushion. said 56 sof- 2 g A,imm-ie` poruueon'utug flexible connection .between thefportion'wkthe top layer which is cemented .to the cushion -and the portions of said layer which'are cemented tof the bottom layer,v
