Replacement Cords for Freedom Walk AFO Drop Foot Brace. Over time, the cords may become frayed or possibly over stretched. This pair of cords comes with new hooks, washers, cord locks, and shrink tubing to replace a single brace's pair of cords. Tools Needed: Pliers (needle nose work best) and maybe a lighter or a hair dryer and some scissors. Now also includes cord locks for the new adjusting feature. All colors are available. Cords can easily last for a year or more. I still have a pair of braces that are several years old and still work great but look a little worn.
