I live in Alaska, its -9 below and -35 to -40 below with the wind. I drove 97.2 miles on the snowmachine and these boots were awesome and kept my feet warm. Size runs bigger than normal and with an extra pair of socks worked great. They are super stiff outta the box and 3 weeks later, their starting to break down and are more comfy.
