OK, my feet use to STAY cold in the duck blind and deer stand. That is always the first thing that gets cold on me and everything else is usually soon to follow. However, I have found a secret. Before you go into the woods or timber or wherever else you are going, take some spray on anti-persperant (Right guard, ect.) and sprayit on your feet, under your arms, on your arms, or anywhere else sweating is a problem. If you are deer hunting you want to find some unscented spray anti-persperant. You will not believe the difference it will make when you don't sweat and if you use anti-persperant you don't have to be cold walking in or worry about getting hot and sweaty only to turn around and get cold. Try it, I PROMISE it works.
