Bought 2 packs for my boys ages 9 and 6. They fit my 9 year old in length but the sock is too small. He says the finger appears strange. They are also too big for my 6 year old (wears size 12-13 shoes). These socks are cool and comfortable. Not too thick, which is nice in our generally warm climate. Kids love the look and thickness of the socks but wish they fit better. It would be nice if they offered more children's sizes. All socks have "XL" written on the bottom, but Revain didn't offer a size selection. I think there are probably a lot of kids under the age of 9 who would love to wear them. Too bad there are no sizes. I would only recommend them to children wearing at least size 2 children's shoes.
