Traditionally, the terminal device of a lower limb prosthesis is a prosthetic foot, called SACH foot. It is a simple device that has a wooden core surrounded by a solid rubber foot. This permits a combination of stiffness with pliability. The cushioned heel absorbs the impact of heel strike.In India, at Jaipur, SACH foot has been modified in a number of ways to make it suitable for barefoot walking.
