I just received these (2pair, L/XL), Sunday 2 Sep 18 and I tried one pair on Monday 3 Sep. I wore them for about four hours. They fit great and the calf compression seemed perfect for my calves. I'm 5'11", wear a size 12 shoe and my calves are 16 3/4"(R) & 16"(L). I'm probably going to order a couple more pairs. I'll write another review after I have more experience wearing and washing them.
