How warm are the boots?
So many factors come into play here. Things like activity, type of socks, smoking, drinking alcohol, circulation, and what you are wearing on your head. We have found that the number one factor in cold feet is a boot that fits too tight. Even though a snug fit is ideal for walking, you should loosen the boot laces or wear a lighter sock for maximum warmth. At Kenetrek, we are trying to be honest with our ratings. If we comfort rate a boot to be warm to 0 degrees, that means we have used the boot and find the rated temperature to be on the lower end of the comfort zone with mild activity. If you would like to compare insulation ratings to other boot manufacturers, subtract 40 degrees.
