A multi-axis prosthetic ankle includes a bottom component connected to a prosthetic foot, a lower leg connection component connected to a prosthetic lower leg, an elastomeric material securely connecting the bottom component with the lower leg connection component, and a mechanical device suspended in the elastomeric material. The mechanical device is formed of a first bracket connected to the bottom component and a second bracket connected to the lower leg connection component. The first and second brackets interlockingly float in the elastomeric material, and are not in direct contact with one another, thereby permitting relative movement of the bottom component and the lower leg connection component by deformation of the elastomeric material. At least one mechanical stop is positioned to prevent the relative angular movement of the ankle from deforming the elastomeric material beyond the elastic limit thereof.
