I haven't done anything too crazy in these yet, but so far so good. If you want want some heavy duty boots that don't weigh a ton, these are a good choice. So far I've made it up some steep, slick hills with no issue in them and hiked some shorter, rocky trails with no problem. Tromped around on concrete an asphalt as well with no issues, and with my beat up feet that means the cushioning is very good. They seem to really lock your ankles down, which is what I wanted for digging into some of the steep muddy trails I hike, but if you want more flexibility you may not like that. The fit is good, I'm pretty average foot wise with a narrower ankle, and these fit snugly but not tight. If you want a lot of stability, good grip, and from what I've seen so far, good waterproofing in a moderate to warmer weather boot, this fit the bill.
