ok, don't laugh. This is for real

When I was in the Marines we would go in the field and we walked everywhere we went, when we would get there our feet would get frezzing cold after a while. Of course we were all wearing cotton socks and were sweating and that was causing it. A crusty old veteran told me to get a pair of calf high panty hose and wear them when we go. It worked like a dream, plus no blisters. The hose wicks the moisture away from your foot, it works better when you don't wear cotton but, will work if you do. I buy new socks every year right before the season and I never leave the truck without my trusty hose. Give it a try, I may not live up north but it get's as cold as a well diggers butt here too.
