Abstract
A foot support for use with a human foot having a forefoot portion that supports the foot beneath the metatarsal heads and an arched midfoot portion that supports the foot beneath the metatarsal, cuneiforms, navicular, and cuboid bones and has a slope between a maximum height on the medial side of the foot support and a minimum height on the lateral side of the foot support. The foot support also includes a wedge fixed beneath the forefoot portion such that the maximum wedge height is positioned beneath the first metatarsal head and the minimum wedge height extends beneath the fourth metatarsal head. The foot support may optionally include a heel portion that supports the calcaneus and talus bones in a neutral, varus, or valgus positions.
Claims15
A foot support for use with a human foot having a forefoot varus deformity, said foot support comprising:
- a forefoot portion configured to support a forefoot of a human foot;
- an arched midfoot portion extending from said forefoot portion and configured to support a medial longitudinal arch of the foot;
- said arched midfoot portion having a slope between a maximum height in proximity to the medial side of said arched midfoot portion and a minimum height in proximity to the lateral side of said arched midfoot portion;
- said slope of said arched midfoot portion having a degree of incline between 8 and 22 degrees;
- a wedge fixed beneath said forefoot portion, said wedge having a maximum height on the medial edge of said forefoot portion and a degree of incline between 0.1 and 8 degrees;
- and
- wherein said degree of incline of said wedge and said degree of incline of said slope of said arched midfoot portion are selected such that together they prevent collapse of the medial longitudinal arch and the forefoot during locomotion.
A shoe for use with a human foot having a forefoot varus deformity, said shoe comprising:
- a body configured to engage the foot;
- an outer sole;
- and
- an insole comprising a wedged forefoot portion, an arched midfoot portion, and a heel portion;
- said wedged forefoot portion having a maximum height on the medial edge of said forefoot portion and a degree of incline between 0.1 and 8 degrees;
- said arched midfoot portion having a slope between a maximum height in proximity to the medial side of said arched midfoot portion and a minimum height in proximity to the lateral side of said arched midfoot portion;
- said slope of said arched midfoot portion having a degree of incline between 8 and 22 degrees;
- and
- wherein said degree of incline of said wedge and said degree of incline of said slope of said arched midfoot portion are selected such that together they prevent collapse of the medial longitudinal arch and the forefoot during locomotion.
A foot support for use with a human foot having a forefoot varus deformity, said foot support comprising:
- means for supporting the forefoot on an incline, wherein said incline has a maximum height on the medial side of the forefoot and a degree of incline between 0.1 and 8 degrees;
- means for supporting the midfoot along a longitudinal arch, said arch having a transverse slope from a medial maximum height to a lateral minimum height and a degree of incline between 8 and 22 degrees;
- wherein said degree of incline of said wedge and said degree of incline of said slope of said arched midfoot portion are selected such that together they prevent collapse of the medial longitudinal arch and the forefoot during locomotion.
