I got an aircast a60 after rolling my ankle. It was nice at first, but I developed a tender spot on my upper ankle where the brace rubbed. I couldn't continue using it because it hurt whenever I moved. So I got a pair of ASOs and couldn't be happier. I've had absolutely no problems with them. They're easy to put on, fit in shoes easily, and they're very comfortable. Now I wouldn't play without them. I think the aircast is best for very bad sprains as it restricts movement more, but the ASOs are better for daily use. Oh, you should use long socks with either, though, or they will be uncomfortable.
