X8 Knee Brace Size Guide
Measure from the center point of the kneecap to 6 inches up the thigh. Measure the circumference of your thigh at that point. With this measurement, follow the size chart below.

WARNING:
- If you fall between two sizes, choose the smaller size.
- Using an X8 that is too large for you will not function as designed and will not protect you properly. It may also cause premature wear of the device and may void the warranty.
