I love the look of these shoes, they are very comfortable but not durable. In less than a year, the treads were almost completely worn out, making wet, flat surfaces as slippery as ice. I only wear them to walk around the neighborhood and to work (I have a sedentary job). I'm not sure how long these shoes should last; the rest of the shoe is in great shape, but the sole wears out so quickly that i hesitate to buy NB shoes every time.
