You will get a lot people saying Mucks are the best. I bought that and went with the Arctic Pro's this year. they are awesome boots, very comfy and light, great for walking, etc - BUT - they aren't that warm. The sole is too thin, and if you sit on the ice for hours with your feet on the ice, the cold will get to your feet. A quick 5 min walk and they're warm again, but I wish someone would've told me that before I bought them.
Don't get me wrong, they are GREAT boots, but they need a thicker sole. Doubled up some very thick socks and my feet don't feel the cold for about 2-3 hours of sitting, but it does get through eventually.
