Abstract
Abstract A running shoe structure which complements the natural shock absorption function of the arches of the foot by redirecting downward forces through the foot both forward and backward during running and preventing the shortening and bunching up of the feet on impact by simultaneously absorbing vertical thrust and controlling excessive lateral motion. A first raised bar in the inner sole immediately in front of the heel serves to hold the heel back while allowing the rest of the foot to roll and pivot over this bar and to stretch forward away from the heel. Medial and lateral arch supports are provided along the two sides of the shoe to keep the mid-portion of the foot lengthened by preventing compression of the medial and lateral arches in the foot. A second raised bar is located immediately in front of the heads of the metatarsals. An outer sole mirrors the shape of the inner sole and with a is secured with a cleating connection to the mid sole. A fabric inner slipper is fastened to the upper portion of the shoe to mold the shoe to the shape of the foot.
