ABSTRACT:
A shoe having an insole with a forepart of leather having the characteristics of upper leather and a back part of fiberboard. A sheet layer of foam material, such as microcellular polyurethane, is cemented to the lower surface of the forepart and a foam cushion, preferably molded of microcellular polyurethane, overlies the back part. The back part of the insole has an opening through it and the foam cushion has a central portion that projects downwardly through the opening thereby providing a thickened foam at the central portion to maximize cushioning at the area of the heel strike. The invention is incorporated in shoes of both the welt-type construction and the cement-type construction.
