YC Running Gear Review 1 My first CWX tights. I bought these last year for the good reviews, and that they were made in japan. Unfortunately, the stitches inside keep rubbing skin hard causing painful rash every time I wore them.Perhaps they are no good for running? Or should I simply wash them for several time before using them again?I wore them four times and gave up. The stitches are killing me while running.I usually wear Under Armour and Skins compression shorts.
