CA 2093023

A shoe (10) having an insole (12) with a forepart (14) of leather having the characteristics of upper leather and a back part (16) of fiberboard. A sheet layer of foam material (48), such as microcellular polyurethane, is cemented to the lower surface of the forepart and a foam cushion (58), preferably molded of microcellular polyurethane, overlies the back part. The back part of the insole has an opening (56) through it and the foam cushion has a central portion (62) that projects downwardly through the open- ing 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.
