Has anyone found benefit from an ankle foot orthotic? I'm thinking it might be helpful for those times when our son has to go places that require more walking than he can do with regular shoes. He can walk relatively far with the orthopedic boot, (the walking cast from after his surgery), but of course not all the muscles are getting exercised when he uses it. At home he only uses regular shoes. He needs a transitional support that lets him still weight bear for longer distances like appointments at hospitals, etc.
