Klim boots are excellent boots, as well as Baffin (I have both). I tend to where the Klim much more because of the rigid soles. I have ridden with my Klim Adrenaline boots in -28f temps and have never gotten cold or wet. I have also had many days where I wore them for 18 hours straight, and when I've taken them off at the end of the day, my feet are nice and dry. I might also add that no matter what the temperature, I don't wear anything more than just a plain old polyester sock. I'm not sure what more you could ask for from a boot.
