A dual cantilevered leaf spring structure may provide a prosthesis for an amputee or supplement the feel and action of a human foot and lower leg. The structure is provided with separate limb members each attachable at its top shank to a mounting platform. The shanks are preferably rigid, but the limbs become resilient and spring-like as they extend away from their mounting. One limb terminates in a toe piece and the other a heel piece. A stump socket interface provides a mounting platform having a slot receptacle and set screw holders for each shank of a limb permits the point of support to be located high off the ground and permits height and, in some cases, cant adjustment. The use of composite or stranded graphite construction flat oval tubes allows minimal width combined with considerable shaping ability which is particularly desirable for constructing braces or structures providing non-prosthetic augmentation of natural walking, running and jumping movements in shoes or boots.
