Abstract
A sole for a shoe is described formed from a composite material. The composite material includes a plurality of plies with each ply having a plurality of high modulus, preferably unidirectional, fibers oriented at an angle from about .+-.40.degree. to about .+-.90.degree. relative to the longitudinal axis of the sole. The fibers are embedded within and bonded together by a low modulus resilient matrix. The sole is highly compliant about the forward roll axis of the sole while providing for lateral stability.
