Abstract
A structure for enhancing the stability of a midsole including a plurality of strands which extend from a position on top of the midsole to a location secured to the bottom of the midsole. The strands are preferably secured to an energy return system which is positioned on the top of the midsole. The initial strike imparted on the lateral side of the midsole compresses both the midsole and the strands. The strands, which separate during the initial strike from the midsole and assume an arcuate shape, enhance the shock absorbing properties of the shoe. As the foot rotates, the heel exerts pressure on the energy return system, and the strands are then pulled inwardly thereby restricting the outward movement of the midsole. The foot is further unlikely to assume a substantially pronated position due to the tension in the strands along the medial portion of structure in combination with the shock absorption upon initial strike.
