RE: Keeping your feet warm.
Although warm, I find the Artic Shields to be bulky and very noisy in the stand. I have them, but quit using them. You are supposed to wear them without your regular boots which means taking them off and putting them somewhere. Where? I have left mine on my stand platform, but that makes it pretty crowded. Then, after you are done hunting, your regular boots are freezing cold and you have to put your toasty warm feet back in freezing boots.
Now I wear a set of neoprene socks with wool over them. That set up inside my new pac boots and I hope to be warm and comfortable this year.
Good Luck.
