I have a pair of Muck Arctic boots I wore last season. Even with wool socks, my feet got cold while sitting at the base of a tree for hours. I was going to upgrade to the next level of Muck boots (I think the Arctic Pros) in a bigger size and double up on the wool socks, but instead I decided to get a pair of Icebreaker boot blankets and carry some hand-warmer packets to throw in there if the Icebreakers are not warm enough on their own. I'll hike in with my normal shoes/boots and throw those puppies on when I get to the stand or tree. Hope it works.
