I've yet to use these under conditions for which they were designed so I will update as needed. Initial inspection indicates these boots are of high quality; stitching is solid and overall design is competent. I feel assured that my feet will not get wet or cold this winter. Some reviewers claim the boots run small. I have other shoes by Columbia so I ordered based upon this and ended up returning the first pair for a half-size smaller. I have small feet and the second pair fit well.
