The central bladder includes an inflatable chamber disposed generally under the foot and the stays each include elongated upwardly extending inflatable chambers. A lateral branch of one of the stays extends across the front of the lower leg between the upper edge of the anterior casing and the lower leg. A manual inflation pump is secured to the lateral branch portion of the one stay and is supported by the anterior casing for inflating the brace to a selected working pressure. The casings and brace are secured to the foot, ankle and lower leg by straps which include quick release fasteners, such as hook and loop fastener strips.
