I always start of light then put layers on at the stand. My feet are the only thing that the cold bothers. I have tried arctic shield boot warmers with both good and bad days, It seemed what worked one day didn't the next. I started taking an army wool blanket and wrapping it around my boots. I also took one for my wife when she hunted on the ground. It helped keep the warmth in. I hope this helps. In OK in the late season the wind would blow from all directions at once it seemed. Happy hunting
