While these boots are just a bit too large (I just have to tighten the laces as much as possible, and they're fine), I would still say that these are hands-down the most comfortable boots I've ever owned. I probably end up walking close to three or four miles in them daily, and they never feel heavy or too-rigid. They also seem to be pretty durable, with no signs of wear on the treads. My advice though, is that if you normally wear a half-size (like 9.5) choose to go down to the next whole-size.
