Second that motion on Danner. Mine are not insulated, just slightly oversized, and I take up the slack with double pairs of socks, and I mean extra heavy wool socks from Canada. This is the most comfortable and warmest combination I have found. That said, I do not normally sit in situations that are ice covered and in the snow, temps might be at or near freezing, but I tend to move around more, only holding slow and stealthy when on a stalk of big game. I treat the leather with waterproofing materials that are relatively effective, such as Snow Seal or similar products. This will last for a day or two of hard use. If you are going to be actually sitting or walking in water for long periods, you need something that is actually rubber or neoprene or similar to stay dry. My rubber boots or neoprene waders are my fall back for such situations.
