Troy Lee Catalyst X Knee Braces 5 5 1 1
I tried the most expensive ones! I tried a lot of knee braces, I snapped my knee sideways and spent some $ on trial and error. As of 2014 these were the best. But as technology changes and these guys compete, 2015 may be different. Either way, these are awesome and you won't be disappointed. June 11, 2015
