I read a lot of reviews and chose these socks because of the price. I received an 8-12 year old pack of 6 dinosaur socks for a 4 year old who wears shoe size 10/11 and they fit perfectly before washing. Haven't washed or dried them yet, but I'm glad I followed the advice of the other reviewers and gotten a size 8-12. The heel of the socks sits squarely on his real heel. I bought this for a ride in the snow in a few months and will try to update this review after it has been washed, dried and worn.
