Cas6969 touched on circulation and how toned and in shape you are has a lot to do with your extremities staying warm. My Caribou Sorel's have been good for sitting, but as mentioned, I don't like to walk very far in them. Muck Arctic Pro boots have been good if you get them in a larger size than you think feel right in the store. I put a 1/4" thick felt liner in mine as well. I've thought about those white Bunny Boots because I see those Alaska Mountain Men guys on TV wearing them all the time. Probably not a good idea wearing white things during our whitetail deer season though.
