Simple and doesnt cost money, I guess thats why we do not hear about it
Something that hasn't been brought up is leg length differences. This can cause you to roll your ankle towards the shorter leg. Mine is 5/8". Finding this out explained why I repeatedly roll my right ankle. Using a lift helped, but it was mainly building ankle strength that prevented any more rolls.
A little late to this thread but I rolled my ankle really bad in March of this year. Took a couple months to get back to normal. One thing that helped me was a CEP ankle compression sleeve that I picked up at a running store. I think it would be a little lighter than a brace and may fit in shoes a bit better.
