For times when I want to immobilize the bend of the big toe joint for a while, but do not want the unevenness of a removable boot, I use bike shoes with embedded cleat. A patient came in with one the other day that I am using for a plantar fascial partial tear. I also use for sesamoid fractures, plantar plate tears, and hallux rigidus.
