My legs feel great!
I was a little skeptical about the reported benefits of these CW-X PerformX tights for running. And the price tag had me hesitating further until I talked with a close friend who recently bought a pair and couldn't say enough good things. I broke down and treated myself to a pair as a Christmas gift :-) I am 5'1" and 135 lbs.....I fall between a S and M size. I ordered the S with the recommendation that they should be snug in order to get the ultimate benefit. The fit is perfect for me in both length and girth while providing enough stretch for a taller frame. You have to take your time putting them on to get them lined up with the webbing hitting the right spots on your leg. I wore them on a 39 degree day on an afternoon/early evening run. This is the first run in a week since being struck down with a stomach virus and completely out of commission. WOW.....I'm a believer!! Usually after a week long break I experience some leg soreness the day after my run.......NOT TODAY!! The CW-X PerformX tights were a perfect companion. During my run I felt great, my legs felt strong, and I was totally comfortable in the 40 deg. temperature with only a mid-weight wool sweater on top. The tie waist and internal key pocket are a plus. Today, the day after, no leg fatigue or soreness at all. So far so good......I'm participating in a New Year's Eve running race and plan to wear the PerformX tights again while making my resolution to invest in another pair!! Thanks CW-X...great item!!

great poduct great price
these were a gift and my wife loved them. she is an avid runner and marathoner so they worked well for winter running.

Great tights
Love these tights. They fit very true to size and are warm enough to wear on chilly morning/evening runs.

these keep my legs fresh.
At first, I was surprised at how much the tights squeezed my legs, but then after a couple of runs, I got used to them, and I like the support they give. My legs stay fresh, and my muscles don't get as tired as when I wear loose leggings. I have two pairs now. This is perfect for the fall.

Perfect Compression
I am an endurance runner and have always needed to wear bottoms with compression. The tights were comfortable ( I am 5'7" and 151 lbs.) and the M was the right size. They did not feel constricting. The wider drawstring is convenient and easy to quickly undo. After a 23 mile training run in these tights, I was hooked on CW-X. I felt minimal muscle fatigue.If only I had found them sooner! The size chart is spot on!
