I love these boots, they are comfy and cute. I can wear a thick sock in my regular size! My feet are always cold and I was looking for something extra warm, I can't say that these are the warmest boots. I went ice fishing in PA and it was a bit above 32 degrees and sunny, I wore thick wool socks and for the first couple of hours I was really warm, with time however my toes did start getting cold and numb a bit. So I guess if you move around a lot you'll be fine but if you're out in the cold without much movement I would recommend warmers!
