Abstract: Embodiments of the present invention relate to an orthotic device used for controlling motion of a human foot in a functionally corrected anatomical position from heel strike through toe off. The orthotic device may include at least one of rearfoot, midfoot, forefoot, and toe regions. In each region corresponding medial and lateral wedges may be employed. In the rearfoot region, the medial and lateral wedges intersect at an expected contact location of a medial side of a midline of a heel of the human foot. In the midfoot region, the medial and lateral wedges intersect inclusively between expected contact locations of a first cuneiform bone and a cuboid bone. In the forefoot region, the medial and lateral wedges intersect inclusively between expected contact locations of first and fifth metatarsal bones. In the toe region, the medial and lateral wedges intersect inclusively between expected contact locations of first and fifth toes.

Abstract: Disclosed is an improved device for supporting the human foot in a more anatomically neutral, more correct position while the foot is in a weight bearing position both in stance and/or while functioning throughout gait in walking, running, or skiing. The present invention is particularly suited to high arched as well as flat feet. The device supports the foot from the metatarsal head area of the foot to the heel. The device includes a wedge that starts low in the heel area and very gradually increases towards the forefoot area so that it is highest in the forefoot area under the second metatarsal head. The wedge drops off abruptly under the first metatarsal head to a level that forms a neutral plane or valgus (lateral) wedge or valgus relationship of a plane from the first metatarsal head to the fifth metatarsal head with the rearfoot. In biomechanical terms, the device is designed to provide a rearfoot varus wedge of from 2 to 7 degrees.
