Abstract
A shoe comprising a sole. The sole includes an upper sole member and a lower sole member of different materials. The lower sole member has a hole extending from its lower side to its upper side, and a projection of the upper sole member extends downwardly into the hole. The lower sole member further includes a longitudinal flex groove extending from a toe region to a front end of the hole, and from a rear end of the hole to a sole heel end. The longitudinal flex groove and hole combine to facilitate transverse flexion of the lower sole member in response to gait forces from the ground and a wearer's foot.
