Abstract
A prosthetic foot comprises a hollow elastomeric cosmesis having a relatively large internal space, a keel of relatively stiff or rigid material, and a stiffener of glass reinforced plastics fitted between keel and instep region of the cosmesis. Front and rear snubbers extend from keel and front and rear stiffeners being portions of stiffener extend from under the keel with radiused ends resting on the sole of the cosmesis. During ambulation the stiffeners provide a primary path by which ground reaction is transmitted to the keel, but ground reaction bringing the stiffeners into contact with the snubbing means is transmitted to the keel via an overload path through the snubbing means.
