My girl is 9 years old and wears a size 4 Big Kid shoes. I have large socks as the size chart says big big kids fit sizes 3-6. Out of the box they were only 2/3 the length of her foot. When putting it on and pulling the leg as far as possible, the heel of the sock didn't wrap all the way around the heel. Very good socks, just a little small.
