I take a size 10 UK shoe. In fact, my New Balance runners are a size 11. I think my foot size is around 10 and a half. The problem I have with these socks in the usual thing: they are TOO BIG! How could these be a 9 to 12? What it a size 9 person supposed to do? Do sock manufactures make socks for people with fat feet and fat ankles? I don't get it at all. If these socks fit me they'd be just what I want: not artificially soft that they'll look wrecked in 2 months, reasonably thick. They keep sliding down my leg. Annoying. Grrr!!!
