The relevance of the prosthetic foot - Ottobock

Designing prosthetic foot systems is challenging. It’s very difficult to reproduce the complex workings of the human foot and ankle. Ideally the foot will be light because its weight is added to the rest of the prosthetic leg. If the foot is too heavy and the suspension of the prosthesis is not appropriate, the connection to the socket and your limb will be affected and also the overall function of the prosthesis.

A good prosthetic foot should also be strong, as it will be taking on large forces and torque as you walk and run. Feet must also be small enough to fit within a footshell, a cosmetic covering for the prosthetic foot, and thus fit within a shoe. Being light, strong, and small, while functional and durable is the challenge.

Early designs for prosthetic feet were often a solid piece of wood. A similar design, the SACH foot (solid-ankle-cushioned-heel) is still in use because of its sturdy function. It is especially useful for individuals with lower activity levels. A SACH foot typically has a rigid inner structure (wood or plastic) surrounded by a compressible foam cosmetic shell.
