Get a set of ice breaker boot blankets from cabelas($50.00) then put some pillow cases(noise suppresion)over them as the the materialis not quite enough for bow hunting. They sell fleece booties to go over the boot blankets but they are hard to put on when you have all your clothes on whereas the pillow cases slip over them easilyand you can tuck them into the boot blankets.They will be good to about -20 fairenheit when you are onstand.
