A walking boot is a special type of medical footwear prescribed to protect the foot and/or ankle. This biomechanical tool can be used after an injury or surgical intervention in the area. These boots may also be used to redistribute weight from one part of the foot to another. Depending on the injury or the recovery process, a doctor will prescribe either a short or a tall walking boot. They will also explain the length of time you are to wear the boot, as well as how much weight bearing is advised.
