Abstract
A prosthetic foot includes an ankle member, a heel member and a toe member coupled to each other for relative pivotable movement with the pivotable movement resisted by elastomeric pads. The heel and ankle member are connected through a joint allowing for translational and pivotable torsional motion of the ankle with respect to the heel and provided with limit stops in the axle and the side walls of the heel member to limit the torsional and translation motion of the ankle joint. The toe member is formed symmetrically to be used for left and right feet with symmetrically positioned and mirror imaged for sections.
