They are soft and good quality! However, I have a very tall 3 year old who wears 10T shoes and I bought a size 5-7 for a roomier fit. They are elastic too! Very happy with the purchase
Pros
Good fit, cute design!
Cons
While these socks are warm and comfortable, they can only be used during the winter months, which means they're not very useful at other times of the year.
