These are the first no show socks that are thick enough to not be torn after many uses yet thin enough to not feel like I am wearing regular socks with my flats. It comes with black, white, and grey which helps be seemless when I have a certain color of shoe on. I walk around a lot at the office and they do not slip off my ankle and stay on for the whole day. Overall I am pleased with the quality of these socks. great buy for sure!
