The OAPL AIR (Tall) Walker stabilises the ankle at 90° with movement restriction. This product provides enough support and durability for inversion ankle injury or post/pre operative use. Air compression allows moulded fit for the leg and provide additional stabilisation. Sole is rocker designed and consists of EVA foot bed and velcro closures. Air circulation through the boot is good too. Foot orthotic can be added inside the liner to support the arch as this product has a wide base and generous strap length.
