I have had frost bite on both feet, so my feet get cold fairly easy when sitting on stand for more than an hour in weather colder that 30 degrees. Ice fishing is worse. I purchased a pair of Cabela's heavy pac boots about 6 years ago and they are hands down the warmest boot have owned. I have not tried some of the others mentioned but I don't need to.
I also have Cabelas Pac Boots 2000 grain thinsulate with Merlino wool socks and polypropelene socks keep my feet toasty warm no matter how cold it gets. Theres nothing more miserable than cold feet. I like my boots.
