See full text

A spring for a spring shoe, the spring including a conical disk, the conical disk having a flexible flange around the perimeter of the conical disk. A spring comprising a conical disk and a ring spring around the conical disk, the ring spring being movable up and down relative to the conical disk to adjust the spring force of the spring. A threaded engagement between the ring spring and the conical disk so that rotation of the conical disk moves the ring spring up or down relative to the conical disk. A damper ring around the perimeter of the conical disk to resist the expansion of the circumference of the conical disk. An eccentric ring or cam to adjust the position of the apex of the conical disk relative to an insole by rotating the eccentric ring or cam. An asymmetric conical disk to adjust the position of the apex of the conical disk by rotating the conical disk. A damper for a spring shoe comprising a flexible container containing a material with little or no propensity to return to its original shape. A spring array for a spring shoe, the springs of the spring array having a reducing force resisting compression over at least a portion of the spring range of travel as the spring compresses, and there being a damper associated with the array to oppose compression of the array towards maximum compression.
