I had the old Columbias that were altogether too heavy and not warm at all. I needed something that could keep my feet warm for long periods of walking and standing on the snow covered ground. These are the best boots ever. My feet are warm all day due to the -32 rating vthey are so comfy and cute as well. Best thing is they are feather light. I can wear a 91/2 or 10 but had to get a 10 with these and do not wear my wool socks as they were nice and snug with only a knee socks on.
