Ultra Ankle braces will fit either ankle when they are new, however once you start wearing them and they start forming to your ankle they become ankle specific and should continue to be worn on the same ankle. 

It is very important that mark the braces L or R (left or right) and always wear them on the same ankle. Where the top strap attaches to the brace there is a white colored tab where you can mark the brace L or R.

If you’re an athlete, we recommend you write your name and/or number as well to identify them if they are lost amongst your teammates.
