The Shell Air Ankle Walker provides the same degree of comfort and support as the Breg’s Vectra product line, but you also get a semi rigid, durable, lightweight shell. Use with acute ankle sprains, soft tissue injuries, stress fractures of the ankle or lower leg and syndesmosis. Use to manage swelling, to stabilize the foot or ankle, and to control foot pain. Use after bunion surgery, tendon/ligament repair, ORIF surgery and archiles repair. The walker is made with a 3-piece shell that can easily be adjusted to fit most patients. The rocker sole helps maintain a more normal gait and the medial/lateral air bladder helps to keep your foot stable. Comes with moisture wicking synthetic knit sock with removable toe cover.
