I have both bunney boots and Ice kings. Both are plenty warm. Bunney boots are a fraction of the cost of ice kings. My problem with the bunney boots where they hurt my feet after a day of use. Might of had to small of size. I think they are both good products.
Have any of you guys looked at keeping you core temp warmer to help with keeping hands and feet warm. I would think that even if you have good boots a cold core may still cause those outer limbs to feel cool. Need to make sure to keep the sweat away from your torso. get rid of the cotton tee shirts and get a good wicking base layer. Twice so far this year I had forgot to get rid of the t shirt before heading out and found myself getting cold even with all the other cold weather gear. Getting that wet tee shirt off and putting everything else back on and I was good to go. A wet cotton shirt will keep you cold in the winter even if you have the right stuff on over it.
