Duran II Waterproof Leather Mid Hiking Boot

Have had a wide-sized pair of these for years. Can't remember exactly but definitely over 5 years, maybe up to 7. Mostly I wear them for outdoor activity with a light pack and a lot of movement patterns upright, kneeling, and some crawling. Also, wear them for some hobbyist shop work on concrete. With some other boots I've had the sole would have separated from the upper by now, but the Keens are completely intact not even one spot showing weakness. The tread is still deep and works very well in the rough stuff. The leather tops are still in excellent condition. The boots are comfortable, the heel squishes the right amount for high impacts (running) and the sole is thick enough to be very protective in very rough rocks. I have a fairly wide foot, sometimes too wide for 'wide' shoes. The wide-sized Durand works very well for me, good room for foot to splay out in the toe box. I am going to say 'runs wide' on fit because these are conventionally sized boots, which for me is a good thing. Only one slight issue for me, in the last 6 months (after years of hard use), some riveted eyelets have popped off down around my first toe knuckles. Since I'm not worried about looks JB weld fixes this issue, and the boots are back to 100% functionality. My family has had many pairs of Keen shoes and so far the brand has been very trustworthy

These boots suffered a catastrophic material failure—specifically within minutes of stepping of a train. The soles did not simply delaminate; the polyurethane structure completely disintegrated on both shoes. I have confirmed this was not caused by chemical exposure, as the crumbling material caused no skin irritation upon contact. The response from Keen was this was normal and expected degradation.
