Have just started wearing the ASO brace and must say that I am very impressed because it offers a balance between firm support and flexibility.
Taping alone is a bit of a skill and a real hassle if you tape too tight.
The ASO is definitely one that has got the balance right. Your foot will not weaken using it. You stay strong in it as you are still execising in it. Listen it's not much money for real help on court. You'll love the strength it gives your ankle. (Buy black because the white gets dirty quickly.)
