It finds that the BYU 2ft prosthetic foot scores highest overall due to its simple, affordable design that provides functionality similar to a normal foot while being durable and easy to clean. The conclusion is that the 2ft prosthetic could allow amputees to have an active life rather than a sedentary one, in line with the goal of bringing hope to amputees.

is “Bringing hope to
amputees, one leg at a
time.”
