Have two - one is shorter - $25 each. Surgical shoe is $5. The boots are for a break, fracture or surgery while it is healing. Both come with shims (to place where there is pressure), shorter boot is an Air Walker and can have air put in or taken out around the top. All three are a size MEDIUM and in excellent condition. I have the size charts and pictures. Approx. sizes: Men 7.5 - 11, women 8.5 - 11.5.Your doctor will advise if this is the right boot for you. If your doctor says the boot isn't right for you and you have not been wearing it, you can return it.
