Abstract: A pair of struts are frictionally and mechanically disengageably engaged with corresponding ones of opposed uprights of the base of an ankle brace walker to provide rigidity to an enveloped foot and ankle. The base includes a plurality of longitudinally aligned laterally offset flanges intermediate laterally aligned flanges, all of which flanges are disposed intermediate the sole and the foot bed of the base to provide rigidity for the foot and with sufficient strength to permit walking without danger of breakage of the base with resulting injury to a user. Cushioning means and strap means retain the foot and ankle comfortably but firmly within the ankle brace walker.
