Cam walkers are often used following foot or ankle surgery or after an injury. These devices help protect the injured area. They provide relative immobilization. They also allow for some limited walking (if this is indicated), and will serve to disperse the force of walking more evenly up the leg, due to the rigid sole and the rounded (rocker-bottom contour) of the sole.
