Like others posted, these socks are not very good. I had originally purchased Hanes at Target and they lasted a year. These are thin (which I don't mind) but they are also very tight even for a tall thin kid with narrow feet. Not only that, but after 2 washes, the non-skid bottoms completely wore away. My poor son went sliding in the kitchen to a big fall because he was expecting to be able to run with some grip on his socks. Don't buy these.
