For cold feet on stand use boot blanket without any boots on, a pair of nylon wicking socks, one pair 100% wool socks and and one 18 to 24 hours chemical heat pack in each boot. Walk in with regular boots on and carry the boot blankets, then take boots off and slip your feet into the warm boot blankets. Ive hunted in below zero weather many times using this set up and my feet stay toasty warm. h.h.
