The only drawback on these sock is that they go higher than just over the calf, they almost go over the knee.  I bought them for my 17 year old son, who has a size 11 foot and they were really long.  He will keep them and wear them because they are soft and well made, but I did have to get him some shorter ones.  Just keep in mind how long they are when you buy them.  I'm considering buying some to wear with my winter boots because they are nice and long and DON'T DROOP.
