Embodiment Construction
[0027] Referring now to the drawings, a prosthetic foot 1 of the invention comprises a body 2 formed of a resilient, semi-rigid material, plastic in the disclosed embodiment, which is formed with forefoot, midfoot and hindfoot portions 2A, 2B and 2C, respectively. A cosmetic covering 3 of the foot surrounds the body 2 as depicted in FIG. 2. The body 2 in the disclosed embodiment is formed by molding or by pouring the material of the body into a negative mold. However, other processes could be employed to form the body 2 such as machining the body from a solid piece of resilient, semi-rigid material, or by using a combination of molding and machining, for example. The plastic of body 2 is an elastomer, polyurethane in the illustrated example but other plastics or composite materials could be used. The body 2 of the foot is shaped and designed to simulate a human foot's hindfoot triplanar, forefoot biplanar and hindfoot, midfoot and forefoot dynamic response windless effect motion cap...
