My 4 and 5 year olds (shoe size 11/12 and 13/14) love them! I'm a big fan of wool socks as I've had bad blisters from synthetic and cotton blends and you can't beat them for quality, price and comfort for precious babies :0)
Pros
cute socks Very warm. Although the mileage is short.
Cons
May not be strong enough to withstand frequent use and wear and tear
