I've only owned them for one day, but like them so much I ordered more. However, they are not a mid-calf sock as described. They come up to almost my knee cap, about an inch below. I have a 32" inseam, 10.5W foot. Love how thin they are without feeling slick like most dress socks. Might be too tight up top for guys with beafy calves. Wish they were shorter, but good enough
