Abstract
A sole for an athletic shoe, such as a cleated soccer or football shoe, comprises a thin, unitary member formed of flexible material. The member has a contour or configuration which renders the flexible material substantially rigid at the arch and heel portions of the sole. This provides substantial support to the arch of the foot. Cleats may extend from the toe and heel portions of the lower surface of the sole member.
