Patent ID: 7727285

Claim:
A prosthetic foot, comprising: a) a resilient elongated foot member, extending between a toe section positioned at a toe location of a natural foot and a heel section positioned at a heel location of a natural foot, and extending through an elevated arch section positioned between the toe section and the heel section at an approximate arch location of a natural foot, the elevated arch section being elevated with respect to both the toe section and the heel section with the toe and heel sections disposed at the same elevation when at rest; b) an elastic arch block disposed below the elongated foot member under the elevated arch section, the arch block being sized and shaped to substantially fill a volume under the arch section, and configured to allow medial to lateral rotation to the prosthetic foot, the arch block also including a toe end and a heel end extending between a medial side and a lateral side of the arch block; and c) both the toe and heel ends of the elastic arch block being angled side to side at a nonparallel and oblique angle with respect to a transverse axis perpendicular to a longitudinal axis of the foot member.
