A prosthetic foot assembly (20) includes an ankle member (22), a heel member (24) pivotally connected to the ankle member, an elongate metatarsal toe member (26) pivotally connected to the heel member, having a rear portion underlying a forward portion of the heel member, and projecting forwardly from the heel member. A first compressible element (32) is engaged between a portion of the ankle member, and a portion of the heel member. A second compressible element (34, 120) having first, and second substantially circular bearing surfaces (122, 124), is engaged between the heel member, and the metatarsal toe member to resist upward pivotal movement of a forward end of the metatarsal toe member relative to the heel member. A portion (126) of the compressible element spaced apart from one of the bearing surfaces has a smaller diameter than the diameter of at least one of the bearing surfaces. Noise abatement features include surface treatments, and modified compressible elements.
