Abstract: A prosthetic foot possessing a forefoot keel cluster (1) which is comprised of three distinct keels. The keels are functionally connected to one another by way of an anterior pitched glider (6) which is positioned above the two lower keels and beneath the upper keel. The anterior pitched glider (6) is tapped and houses an anterior screw (7) which acts as a worm gear to reposition the glider with respect to the forementioned keels of the forefoot keel cluster (1). The position of the glider determines the functional lengths of the two lower keels and their associated deflection properties. A rearfoot keel cluster (2) also exists with a posterior pitched glider (14) and posterior screw (15) that serves a matching function to that of the anterior pitched glider (6) found in the forefoot keel cluster (1). The rearfoot keel cluster (2) is functionally connected to the forefoot keel cluster (1) by way of a keel divider (10).
