My daughter has owned these boots for two full winter seasons. She wears them every week day during the spring, winter and fall to work as a stablehand in a sometimes very muddy, cold, wet paddock and barn area. She loves them. They keep her feet warm and dry all the time. I just took a look at them to see if they need to be replaced yet, and they do not. They are in great shape. Great boots. I owned a pair of Sorels for 15 years before they needed to be replaced.
