A prosthetic foot is designed to mimic a normal foot during the act of walking. It is part of a trans-tibial or a trans-femoral prosthesis and often the first component to wear out, meaning that we often replace prosthetic feet even when the rest of a device is serviceable.
No matter how many spare feet we order, we always run out. This is partly because we have a steady flow of new patients, but also since of our patients who use devices which include a foot, continue to come for replacements. It’s like needing to replace the tyres on your car – only far cheaper, and absolutely essential for quality of life.
