I've always had a pair of 800-1000 gram boots, like Danner Pronghorn's, that I can pair with different thicknesses of socks that would carry me through most of the Midwestern deer season. Then I would pack along some boot blankets to wear over them in late season hunts. That way my feet didn't overheat on the hike in but I could still keep my feet warm when in the stand. I think of it kind of like a layering system for your feet. Worked for me and I have cold feet, hands, head, neck, body, you name it! I hate the cold!! Lots of good advice here from everyone, you should be able to find something that will work for you.
