Abstract
A shoe incorporating dynamic Orthotic means which adapt to the foot in a prescribed manner, controlling heel "strike" and weight bearing loads, establishing a cup-shape to "catch" the heel and foot to stabilize it, balancing and maintaining the sub-talar joint in a neutral attitude and the mid-tarsal joint locked, enabling the foot and ankle to maintain optimum integrity as an efficient support and propulsion system, and resisting the symptomatic tendency for the sub-talar joint and foot to overcompensate and overstress the anatomy.
Claims22
Orthotically dynamic footwear that adapts to force loadings which are directly proportionate to the tendencies for a person's foot to distort, and including;
- a sole of flexible and resiliently depressible material complimentary to and underlying the plantar surface of the persons foot, an upper of flexible material continuing from the perimeter of the sole and fittedly embracing the heel to forefoot of the persons foot, the ground engaging plantar surface of the sole having a depending rib of increased depth extending from the toe portion of the sole to the outside of the heel portion thereof and continuing peripherally around the heel establishing an underlying cavity.
Orthotically dynamic footwear that conforms to a person's foot configuration while adapting to force loadings which are directly proportionate to the tendencies for the foot to distort, and including:
- a sole of flexible and resiliently depressible material having an unweighted formed condition complementary to and underlying the plantar surface of the person's foot, an upper of flexible material continuing from the perimeter of the sole and fittedly embracing the heel to forefoot of the person's foot, the ground engaging plantar surface of the sole having a depending rib of increased depth extending from the toe portion of the sole to the outside of the heel portion thereof and continuing peripherally around the heel establishing an underlying cavity, said sole having a weighted deformed condition adapting to force loadings applied by the pressure of the person's foot in opposition to a supporting surface engageable with the plantar surface of the sole.
Orthotically dynamic footwear that pneumatically adapts to force loadings which are directly proportionate to the tendencies for a person's foot to distort, and including;
- a sole of flexible material formed into a multiplicity of nervatures by first and second layers of flexible material welded together to form gas tight cells of the sole and by a third layer of flexible material overlying the cells of the first and second layers thereof forming gas transfer channels therebetween to control gas pressures complementary to and underlying the plantar surface of the person's foot, and an upper of flexible material continuing from the perimeter of the sole and fittedly embracing the heel of the person's foot.
