In bitter cold weather (WI, not NC), hunting out of a treestand, and depending on the gates that are open have a long vs. loooooong hike to get in, I dress light and pack in my heavy stuff. But feet... I've yet to figure out feet. If it wasn't such a bitch to pack in and then change into heavier dry socks/boots once out there, would do it. Never had a hike-able pair of boots keep me warm after sweated up, then standing still on a thermoconductive metal grate for ten hours. Question if it's possible! Tried carpet, boot blankets, fancy insoles, chemical warmers, various boots/sizes/socks.... Never tried the electronic stuff, guess that's next.
