An inner brace member comprising a U-shaped upper end portion engages the leg above the ankle and integrally formed with the U-shaped member are downwardly extending arms which are pivotally mounted on the upper edge portion of the foot plate. The inner brace is flexible so that it permits inversion and eversion of the foot as well as unlimited dorsiflexion and plantar flexion movement due to the pivotal joint in the inner member. An outer brace member formed of relatively rigid material has a stirrup which fits beneath the foot plate of the inner member and has a U-shaped brace member which fits over the brace member on the inner member and the outer member has a pair of integrally formed arms extending downwardly to a pivoted joint disposed over the pivoted joint in the inner member. The outer member is also provided with hinges on the downwardly extending arms hinges permit limited inversion and eversion movement of the foot.
