WARNING:
Your braces come with two different optional thicknesses of Patellar Shell Pads so that you can get the brace to fit as snug as possible against the sides of your knees.
Many people have smaller or larger than normal upper legs and many people have smaller and larger than normal lower legs. To accommodate this Mobius offers Complete Pad Fit Kits for the X8 Braces.
For example: If you fit a Small or Medium brace, but your lower leg is relatively larger, then you could replace the Tibial Shell Pads with thinner pads from a Medium or Large Pad Fit Kit. And you could replace the lower Straps with larger Straps from a Medium or Large Strap Kit. The same can be done for the upper leg.
Your braces come with optional degrees of extension stops to limit full extension if desired. The extension stop installed on the brace is at 0 degrees, and included are 4, 8 and 12 degree stops.
Note: If the measurement falls between the two sizes, select the larger size.
