A prosthetic foot is characterized by the provision of one or more bladders to vary the performance characteristics of the prosthesis. The bladders preferably include multiple chambers formed by full or partial bifurcation of the bladder, and may be tapered to permit operative alignment of the bladder with certain structural members of the foot. The pressure in the bladder is preferably alterable through the provision of valve means communicating with the bladder. A retaining strap is preferably provided to limit the movement of certain structural members of the foot with respect to other such structural members.
