This is a general guide, select the R3 Sport if you're unsure. If you have any questions  please contact us!


If you have a previously injured ankle, data shows that it is more likely to be re-injured than an ankle that's never been injured. In this case, you may want to use a more resistant strut. If this guide shows you're in the R3 Sport range you may want to consider the R3 Pro HD for your previously injured ankle. This is contingent upon having regained full pain-free range of motion with zero or minimal residual pressure point pain. Use of a compression sleeve between your sock and brace is recommended for these conditions.
