  • Patent number: 11737508
    Abstract: Systems and methods are described for a shoe sole for relieving pressure from a wearer's metatarsal heads. In one aspect, a shoe sole comprises a shoe outer sole comprising a shaft region, a ball region, and a toe region. The shaft region underlies metatarsal shafts of the wearer and comprises a first lower surface, the ball region underlies metatarsal heads of the wearer and comprises a second lower surface, and the toe region underlies phalanges of the wearer and comprises a third lower surface. The second lower surface is raised relative to the first lower surface and the third lower surface.
    Type: Grant

  • Publication number: 20140276094
    Abstract: An apparatus is provided which provides proper compression of the soft tissue to simulate the joint positions, force applications and proprioceptive feedback of the natural foot in mid-stance gait and captures the topographical surface of the foot for orthosis production. The apparatus provides proper soft tissue compression while allowing an optical scanner to visualize the modified topographical skin surface. The apparatus includes an optically-transparent membrane to deform the soft tissue of the foot and an optical scanner configured to scan the foot through the membrane.
