Abstract

Abstract The sole of a bed shoe has a perforated plastic lower portion and an upper portion comprised of a polyurethane foam cushion. A polyurethane foam anklet is affixed to the sole so as to substantially surround the wearer''s heel and ankle. The top of the anklet is adjustably fastened about the lower portion of the wearer''s leg and an adjustable strap extends from the toe portion of the sole to the top of the anklet to limit downward motion of the wearer''s toes away from the leg. A strap extends from one side of the sole across the wearer''s foot to the other side of the sole; and slidable members are located at the heel so as to be extendable outwardly for preventing inversion and eversion of the foot. A two element strap is detachably affixed to the shoe''s heel. One element is adapted to be grasped by the wearer''s hand so that the foot can be pulled by the heel toward the wearer''s body. The other element is adapted to extend over rollers or the like below the wearer''s foot and then back to the wearer''s hand so that the foot can again be pulled by the heel away from the wearer''s body. In this manner, the wearer can alter the position of the foot and the leg can be exercised.
