Uninsulated with some space for thicker socks, but still able to move toes. good wool socks. Add in toe warmers as noted above. insulated overboots like a boot blanket if sitting still for long periods.
I spent all of my childhood with bad socks and 200-400 gr thinsulate insulated boots. Main reason I would get out of my tree stand early was toes so cold they hurt. Realized my feet were sweating when I would walk to the stand and then they just got colder and colder. I got to where I would wear running shoes to the stand and then put on my boots. Now I have uninsulated boots with good wool socks. key is to allow some room for you to move your toes. Boots too tight will cut off some of the circulation and make your feet colder. Toe warmers added on colder days. Overboots have been great for stand sitting. Even better was sitting in a blind with a small heater.
