RE: Keeping Warm/Heated blinds
Since your here, the general consensus from most of the posts on boots were that they should not be tight, you need room to wiggle your toes. Then use one polypropylene liner sock and one thin wool or thermax sock. You can use antiperspirant on your feet beforehand to reduce sweating. If the hike to your stand is a tough one and leaves you and your feet sweating, consider bringing a change of socks or taking out your feet to cool down and dry before setting up.
Boot type doesn' t seem to matter though pac or mickey mouse? boots seem to be the warmest, maybe too warm. IF your feet are dry and you have room to wiggle your toes but your feet are still getting cold very quickly then consider adding those instant heating pads to your boots once your on stand. Remember, whatever you do eventually your feet will get cold, don' t expect to sit on stand all day 8 hrs in freezing weather not moving and wonder why your feet are cold. Again hope it helps and check the old posts, they will basically tell you all of this. Take care.
