I do not have any braces, though i notice I walk best in firm shoes like dansko clogs, hiking boots and I do pretty well in my ski boots too. My physical therapist has never suggested any kind of brace. I have paralysis in my left little toe, otherwise everything else seems to have some near normal range of motion and varying strength.
I can be walking fine one moment then without warning to a funny little drunken dance trying to catch my suddenly lost balance.
So, I’m trying to increase my stability.
