Review on Under Armour Youth Team Over The Calf Socks, 1-Pair - Ultimate Performance and Comfort for active Youth Athletes! by Arturo Reyes

Got red for baseball for my 10 year old. Big size hardly fit him. He has shoe size 6.5 for tall children / 7.5 for women / 5.5 for men. At the heel of the sock you have to pull a little to reach the heel. Otherwise he says they are comfortable. There seems to be enough room in the sock. Not too fat. I can't comment on durability as he only wore it once.
