In one embodiment, an adjustable prosthetic ankle separate from a prosthetic foot includes an upper coupling member, a lower coupling member that couples with the upper coupling member, and a flexion angle adjustment mechanism associated with the coupling members that enables a user to change a relative angle between the coupling members, and therefore a flexion angle of the prosthetic ankle, without using any tools.
