Lightweight, comfortable right out of the box, secure footing on all kinds of different surfaces. I work in construction and walk on concrete, asphalt, dirt, gravel, wet and dry grass, etc. I haven't felt like I was going to lose my footing yet. They are so lightweight that they feel like a pair of running shoes. And no break in period at all. I've owned all kinds of much more expensive boots that took along time to get broken in and comfortable, some of which were painful for a few days. These feel like they are already broken in right out of the box. If you are on your feet all day especially on solid surfaces you will love these boots.
