The ISO Preferred Stable & Secure Ankle Brace II (AN35x) features a configurable jointed rigid ankle brace support system that allows for attaching or detaching a rigid high ankle/calf extension. The detachable posterior panel supports the calf in addition to the ankle, giving patients the option for added support above the ankle. Brace combines a soft fabric surround with a rigid foot plate and comfortable padding and provides advanced stability and improved support for ankle injury treatment. Lightweight, rigid support helps prevent abnormal ankle inversion, eversion, and rotation while offering natural, unrestricted plantar-flexion and dorsi-flexion movement. Sizes S to L; select left or right foot.
