I have always had cold feet when sitting in a deer stand. Back when I ran heavy equipment, I wore Sorel pacs. Those felt lined boots didn't work for me as my feet sweat and the felt liner got wet. Vapor barrier socks would have helped, but I didn't know about them at the time. If I'm active, I'm OK, but sitting is a problem.
I just ordered a pair of Irish Setter boots with 1600 grams of Thinsulate and boa cable closures. You twist the knob on the front of the boot to tighten the steel cable "laces". A buddy has them and likes them very much.
I generally like to wear liner socks with a medium weight oversock, assuming the boot has enough room for all that. As I have gotten older and my feet have gotten flatter my boot size has gone from big to Sasquatch. It's hard to get boots big enough to fit my feet plus two pairs of socks.
