Customer feedback

Comments: Stats-- 5'7" - 5'8", 30-inch waist, 30-inch inseam, 166 pounds.  I fell in the "Gray" area on the fitting chart between small and medium.  I got the Medium size and they fit great.  They stay put while running and feel "springy". I had been running in Saucony tights rated to 35-40, but temps kept getting lower and I needed something a little warmer.  I especially like the no zipper at the ankle feature unlike a lot of running tights.  Could've been mental, but I banged out a 10 mile test run in them and bested my 10 mile time by 2 minutes on a route with killer hills.  I definitely found my winter running tights in these and now I'm looking at other CW-X products to try out for all seasons.
