I LOVE these boots. This past winter was one of the coldest, longest winters on record for the midwest. My feet were never cold! i had yard duty everday outside my school for 20 minutes and i walked my dog every morning (sometimes the temperature was -15c to - 20c....or single digit temperatures US) and my feet were warm and dry everyday. I highly recommend these boots for winter for those who want warm, dry feet in cold, snowy weather!!!
