A leg prosthesis is comprised of durable plastic material (used in its structural columns) and cotton material (used in its thigh and calf straps) to permit for a safer, lighter, and more comfortable prosthesis. The structural designs of this prosthesis makes it multifunction al such that it is able to support the function of the thigh and the leg muscles, the knee cartilage, t he kneecap, the foot and the arch of the foot. The pressure from the person's body weight and that extending from the lower legs and the feet is transferred to the hinges of the prosthesis. This supports persons with weak muscles of the leg in standing up or climbing steps. The use of zipper in th e thigh and the calf strap of this prosthesis allows for the uniform and accurate distribution of the pressure exerting on the thigh and calf muscles. The lower structure of the prosthesis allows is to easily glide into the footwear. This prosthesis is useful for patients who have pain in any part o n the leg.
