I was a little disappointed about how tight these were in the calf area. Also, the first time I wore them they left black marks on my legs. I sprayed them with protectant hoping that would keep the dye from leaving color on my legs but that didn't do any good. Unfortuntely, the window has expired to return them so it looks like I will have to make do. I would suggest trying them right away, hopefully I just got a dud pair since the other reviews have been good. If anyone has any suggestions about how to fix the dye problem, please help!
