they are thick but very comfortable easy care, not a true compression athletic sock at 15-20mmhg
PAINLESS SUPPORT SOCKS!, February 3, 2015 By Debra H. (Frankfort, IN)
I LOVE these socks! They feels like cotton, regular long socks, just with a little extra support. I have tried the white as well, and ordered the grey this time. Both were very comfortable and fit perfectly. I wear a 10.5 B shoe, so the Large size in the sock was perfect. However, unless something has changed over the last 3-6 months, I do not recommend the black. For some reason, the Black pair run small. I ordered some twice last year and the entire sock was too small and tight. even if I had been able to get it up onto my leg, it never would have come near to just below the knee. BrightLife Direct did offer a refund but I just exchanged them for a pair of white, and was given a free pair for my trouble.

I ordered these for extra support for my legs while exercising. I found them to be thick and hot and the band going around my feet makes my arch's cramp. Went to a running store and bought some CEP for a 5K I'm doing tomorrow.
