I have had these boots for approximately 6 months as of this review. I am an EMT in an extremely busy service area and these boots have received more wear and tear than most would in a year. They have held up extraordinarily well I am happy to say. I have worked these boots in mud, blood, and floods and I have not slipped or slid once. I have had someone run a bariatric stretcher, with a patient on board, into my foot and didn\'t have a bruise let alone a twinge of pain. These boots are seriously well built and durable. Mine have been scuffed and do show the typical signs of heavy wear and tear though. The rubber is starting to separate from the leather at the heavy strike areas, only slightly though. I usually have to dispose of a pair of boots at the 6 month mark because they are simply uncomfortable and have been completely worn down. These boots have just gotten more comfortable with time. I work in a very humid climate with hot weather so I am looking forward to see what summer brings, so far though I have had minimal foot sweat. As far as smell, extremely minimal. I\'m not embarrassed to take my boots off at the station. I highly recommend these boots for anyone, especially those that face heavy usage in them.
