Artificial leg for a below-the-knee-amputee. The structure of this replacement leg is plastic. It is encased in polythene foam and would be covered in a PVC stocking to make the leg les obvious. The polypropylene socket is thermoformed (heat-shrunk) over a cast of the wearer's stump. A nylon shank, which has been rotationally moulded, connects the socket to the foot. Adjustments can be made via nylon alignment couplings. The foot has a wooden core encased in polyurethane foam.
