After I sprained my ankle, I was limping everywhere and a doctor told me that this would be great support. It really was, I was able to walk around with less limping and it reduces some of the pain. It's also great because it keeps your muscles warmed up.
It provided my ankle with great support after I hurt it. Your ankle doesn't really sweat so I didn't have to worry about washing!
I'm not really sure how long you would be able to use it for until it all just falls apart! Or can you only use it once?
