I will try not to repeat information from the previous articles on the CWX tights already posted but these articles were excellent and comprehensive.

I was very surprised when I first ran with these tights. Everyone who owned a pair was raving about how they reduced muscle soreness and made them feel great during a run. I was not different. I felt faster and my quad, calf, and hamstring muscles felt supported. Interesting that what I experienced was the same as what the company was proclaiming:

Established in Japan in 1991, CW-X based its designs on the human body’s unique motion during exercise. Perfect for running, cycling, climbing, and snowsports, their conditioning tights provide a host of benefits to your body, including key muscle group support, increased endurance, shorter recovery times after exercise, lactic acid buildup prevention, and precise knee joint alignment.

Although the price point for the tights is a little high, I recommend these to anyone who wants to expand their running wardrobe and feels they have everything. Also, I did feel these tights were of benefit to my muscles and enabled quicker recovery time between runs.
