RollerFoot provides true hands free mobility that no crutches or knee scooters with a handle bar can compare to. Only RollerFoot allows you to use both hands to carry items in each (hot tea in this example) while you have a broken ankle or foot, in a cast or orthopedic boot, and non-weight bearing for six weeks Customers repeatedly confirm that RollerFoot performs much better than the stump crutch iWalk-Free.
