introducing the Royal full shell Walker 2 size small which is shoe size 5 through 8. the full show Walker to from DeRoyal comes with a unique air compression system that allows built-in medial and lateral pumps around the ankle and allows straps to hold your ankle and foot in place while doing daily activities. the footbed is capable and wide enough to accommodate a variety of foot shapes and dressings. The air pumps are on the side and to add air all you have to do is press the blue button for compression and as you can see in the picture there is a little flap that covers a small button to allow the air to be released. I was supposed to have foot surgery and this was ordered by the doctor's office but when I went in for my pre-op appointment after reviewing my foot after the swelling went down the surgery was no longer needed! this is available for sale offers are welcome and I would appreciate a quick sale.
