Abstract
The construction of a shoe which includes shock attenuating members in the forefoot and heel thereof. The shock attenuating members in the heel of the shoe are in the form of a pair of vertically spaced, resilient cantilevered members, each of which comprises a substantially U-shaped air chamber having a load alignment surface for centering loads at heal strike while concurrently transferring peak loads to the outer perimeter of the cantilevered shock attenuating members. The forefoot shock attenuating member comprises a plurality of segmented air chambers in a planar relationship with each other disposed between the midsole and outsole at the forefoot thereof to properly balance and stabilize loads during running and concurrently maximize durability, cushioning and comfort.
