My six year old son wears a size 12 and the size M fits him very well and there is room to grow. He likes being able to put his socks on or fold them. They are of good thickness, not too thick or thin. For the price of a five pack (I got it as an add-on and bought three packs) you can't go wrong. Two thumbs up for these socks.
