I wear Columbia Bugaboo boots...and was down to -20, snow, and wind here in Montana...if on the move, I never got cold....

If I stopped, somewhat chilled...and these are 4+ years old. When I am off the ground first thing, I had no problems.

I am going to hunt Alberta next year...and will probably make a investment on a new pair of boots. By the way...They are the most comfortable boot ever.

Bought at the outlet mall from Columbia ( look on ebay....people buy em there on sale) around $75 bucks I hink.

rubber bottoms.....leather uppers I water proofed.

just my feedback.
