        Comments about Zoot Sports Men's Ultra 2.0 CRx Sock:

        Okay, I was at first skeptical of the concept and claims , BUT now I am a "true believer". The calf support really helps when punishing yourself on a long run or race. Ankle support is especially good and they do calves stay in place. I suspect they would also help with shin splints but I'm no orthopedist.

        Don't think twice, get them!

        Good product, just too difficult to put on and definitely not something you can quickly pull on in a triathlon transition.
