The most-advanced walking boot ever, engineered to provide the ultimate in protection, comfort, and edema control. Featuring a durable, semi-rigid shell that helps support the limb while providing full-shell protection. Overlapping Duplex air cells line the shell providing intermittent pneumatic compression for 3x faster edema reduction. The front panel is pre-inflated and combined with the overlapping air cells, providing a 'total contact' fit. SoftStrike technology absorbs and dissipates shock, while the lightweight and lab-tested rocker sole combine to encourage a natural gait and a continuation of everyday activities.
