Abstract

A suspension system for shoe soles includes an insole mounted on the upper surface of an outsole and containing shock absorbing inserts in forepart and heel areas thereof. The forepart insole insert comprises a shock foam and the heel insole insert comprises polyurethane. Above the forepart area of the insole is provided a midsole containing a polyurethane shock absorbing insert which abuts against the foam insert in the insole to increase the cushioning effect on the forepart area of the foot. A two-layer socklining completes the suspension system. It includes a lower layer of shock absorbing foam and an upper cover of coagulated urethane. The socklining completely covers the footbed. The suspension system provides greater comfort, shock absorption, and cushioning to the wearer and is particularly suitable for women's dress and casual shoes.
