Hey having sprained both my ankles countless times and fracture. I really recommend only using a brace when you have to. There comes a point where your ankle will start to depend on the brace and not become as strong as it can be. Meaning, once you take the brace off and play, you're likely to sprain it again.
Use the brace if you really must play while youre not fully recovered, but otherwise try and strengthen your ankles.
