In a stand I will take off my boots and wear down booties, if really cold I will put a chemical warmer by my toes. I also bring a blanket or overalls that have full side zips and put these over my regular pants. Insulated boots don't have much insulation in the foot and the sole acts like a heat sink. I add felt insoles under the foam factory ones and it helps a lot. I usually go up one size for winter boots to do this. Mouse boots will keep your feet warm to about as cold as you would want to hunt in, but they are not great for walking and I get that swamp foot feeling if hiking much. A change of socks helps with this.

The warmest socks I have tried are hand knit Alpaca, these and a liner are really good.
