I bought these socks for my 9 and 10 year old girls. They wear shoe sizes 3 and 5 (large sizes for girls). They sit on it very well. They often use them for running long distances. Girls like the way they feel. However, the socks are definitely rather thin. I don't expect them to last more than 6 months. If you are looking for socks for active girls, you can keep shopping to find more durable socks. But they fit well and feel good on my girls feet.
