  • Patent number: 5311677
    Abstract: A shoe having an insole with a forepart of leather having the characteristics of upper leather and a back part of fiberboard.

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.
