I bought a size 11-13 for my child who wears size 5.5 "big kid" shoes. They fit well but don't take much extra room. One pair had a hole in the heel the first wash, the rest lasted a few months. They were pretty cheap for so many pairs so I still think they're decent quality for the price. There is nothing to complain about in terms of comfort. I like that they are mainly cotton. The thickness is what I expected from such a sock.
