A prosthetic foot assembly includes an ankle member, a heel member pivotally connected to the ankle member, an elongate metatarsal-toe member having a rear portion underlying a forward portion of the heel member and projecting forwardly from the heel member. The metatarsal-toe member is pivotally connected to the heel member. A first compressible element is engaged between a portion of the ankle member and a portion of the heel member and a second compressible element having first and second substantially circular bearing surfaces engaged between a portion of the heel member and a portion of 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 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 first and second bearing surfaces. Also disclosed is a prosthetic foot assembly incorporating noise abatement features including surface treatments and modified compressible elements or pads.
