I've been wearing soccer socks and baseball socks but need something that less poly to keep my feet dry. My main problem is that I have 21" calves and at the knee, I'm 17. You get the picture, big guns which if the sock doesn't go up past, the sock falls down into my boot. Because the velcro side of my boot doesn't close all the way due to my large calf size, the scratchy part can rub my leg when this happens. So, who know of a good, long sock that can cover my calves and keep my feet dry? By the way, through a search here I found the 511 Tactical socks but they are only 9" tall and no way tall enough. Any other ideas? Thanks!
