this winter I decided to try KEEN Utility . I heard great news about it . They have been true to size and support my ankle and arch perfectly. I was concerned that they were too heavy, but I haven't experienced any fatigue from them - I never have sore feet after a long day wearing these boots. The sole is firm enough to prevent rocks from hurting my feet, but still has good grip and flexes enough when I walk - the perfect balance for me.I am completely satisfied with them after wearing them for the last three month, but I am looking forward to seeing if they are too hot for wearing during the summer . I found a siter earlier and was very helpful for my decision . http://www.bootratings.com/
