Big thanks to CTi, for helping me out with such quality custom Knee braces!! Just got a fresh pair for moto riding this offseason!!. I have spent a lot of time wearing knee braces in my day, having ruptured both my ACLs. Did one when I was 16 from soccer, and the other a couple years ago during my Olympic experience. These guys got me through what could have been a disaster. The custom Stars and Stripes knee brace won the bronze with me and is hanging on my wall:).
Anyway, I have tried a bunch of braces and highly recommend CTi based on comfort and performance. Bryn and I use them every week, for our Dirtbikes. Don't even notice em on after awhile. So if you have any issues with knees, or just need braces for protection, look up Ossur to find CTi Custom braces.
