"I have been trying to find a cotton blend no show sock liner that truly doesn't show. I was excited when I found these; however, I really wish I hadn't wasted my money. I have a narrow, small foot and these are so uncomfortable even on me. I'm not sure how anyone can wear them. Even after a short time of wearing them, they have dug into my feet so much. It's extremely painful - both at my toes and my heel. I guess I'm going to have to throw $16 in the trash. Or I've considered cutting a slit in the liner so maybe they won't cut off my circulation so bad, but not sure if the slit will continue to get bigger or not. I guess it's either that or simply throw them away though. Very disappointed in this product."
