Abstract

A shoe including a detachable heel and two rigid sole sections hinged together along a hinge line that runs directly under the front of the first and fifth metatarsal heads of the foot of the wearer. The rear sole section of the shoe is flat and includes two downwardly projecting studs that engage two corresponding sockets in the detachable heel. Heels of varying heights can be attached to the shoe. The shoe upper associated with the front sole section and the shoe upper associated with the rear sole section do not make contact throughout the normal range of motion of the shoe when worn by the wearer. The shoe has sufficient torsional stiffness such that all flexing of the shoe and foot is confined exclusively in the direction defined by the hinge.
