What is a good ankle brace for Tumbling and Gymnastics?

I'm not a tumble, but I'm a distance runner in track. I twisted my ankle badly, and while it was sprained, I wore a brace. It was simple and cheap, from the pharmacy. I'm not sure what you're looking for, but there are many selections to choose from at CVS. The brand doesn't matter, because any brace helps to a certain extent. Good luck finding one. :)
