Find the Right Fit:
- Stand with your foot flat on the ground and your lower leg upright.
- Place measuring tape flat against the skin (not tight) and wrap it around your lower leg about 2-3 inches above the ankle bones, as shown.
- Use chart to find your size. If you land between sizes, choose the larger option.

A correctly sized brace will feel comfortably snug and supportive without being excessively tight.

60° molded stabilizer proven to reduce rolls and sprains

The combined stirrup and low-profile brace design allows for a highly-responsive support that helps protect against medial/lateral forces that can push an unstable, injured or recovering joint beyond its comfort zone.
