I have been hunting for about 13 years now and I have yet to figure out how to keep my feet warm while deer hunting in the extreme cold. It becomes painful after a while and I tend to not enjoy the hunt as much and just want to get down and go turn the heater on in the truck. I have tried batterie heated socks (which do not work) and the hot hands you can stick in your boots. The problem with those is that once you stop walking the dont put out any heat so you then have wet feet from the sweat which becomes even colder. Any advice you guys have would be much appreciated.
