Buellhunter is right it is next to impossible to find a boot that is a great walking boot with one that is extremely warm.If you have a short walk to your tree stands I would be looking hard at the Alpha Burley 1200's or a pack boot with up to 2000 grams of thinsulate.
For my style of hunting,I am typically in a stand for half the day and on my feet the other half,and I can't stand a boot that is clumsy and doesn't enable me to walk quietly.My go to boots are Danner Canadians and Schnee's Hunter pac boots.Both have air bob soles both are reasonable warm and neither are clumsy.When it is extremely cold or I am in for an all day sit in cold weather the ice breaker over boots go in my pack.They work great,some people put chemical pack hand warmers in the ice breakers and take their boots right off.Making sure you have a great pair of socks like a good heavy Merino wool sock (Ulfrotte brand is awesome) and make sure your boots are plenty big as to allow room for circulation.
Good luck!
