The present invention relates to a prosthesis (20) having a substantially rigid log member (22), wherein most of the bending takesplace about a confined ankle region (26) relatively low to the ground, and in a flexible toe (28) and ankle (26) section, wherein the bendingof the prosthesis (20) more closely resembles the bending of a normal ankle joint. The confined bending helps to reduce the amountof horizontal deflection caused along the ankle section (26) by the upward deflection of the prosthesis (20). The present invention alsocomprises a tubular leg member (22) that is detachable from the ankle and foot member (24), and a heel member (40) extending rearwardlyfrom the foot member (24) which is also detachable therefrom.
