<p>A wedge undersole (17) of triangular shaped configuration as viewed from a side thereof is integrated to a mid-sole (16) of a sole assembly (14) formed of an impact-absorbing material and having a thickness which varies over the length of the shoe, having flat top and bottom surfaces, and having its greatest thickness at the heel (27) of the shoe and tapering in the direction of the open toe (51) region formed by an upper assembly (12) secured to the sole assembly (14). The upper assembly (12) is adapted to surround the heel sides and dorsal portion of the foot. Preferably, the upper assembly (12) has a heel region (27) extending upwardly from the sole assembly (14) and forward portions divided into left (44) and right (46) flaps. The wedge undersole (17) ensures that the top surface of the mid-sole (16) extends upwardly and forwardly in the direction of the open toe region (51) of the shoe with the front surface (33) of the wedge undersole (17) terminating at the mid-metatarsal of the foot. The weight of and pressure on the forefoot is fully relieved while the portion of the mid-sole (16) from the termination of the wedge undersole (17) at the mid-metatarsal acts to fully support the forefoot at an upwardly oblique angle. That portion of the mid-sole (16) also underlies the forefoot to completely protect the forefoot from impact along both sides thereof at the open toe region (51) of the shoe, and at the front of the mid-sole (16).</p> |
