If you are looking for a little more cost effective option, might I suggest something from HiTec's Magnum line of boots. They are mainly service boots so the soles are not quite as aggressive looking, which may or may not be a good thing depending on your perspective, but they are very durable, comfortable, and tend to be a much better value than many of the big name companies. I've been hooked on HiTec shoes since the early '80s and have never been disappointed with any of my purchases.
