I'm not an avid trail runner.. I mainly run on roads, so I don't have much experience with trail running shoes, but I can say I'm extremely happy with these shoes so far! Many reviewers have said this shoe feels like a sock... very true. They are so light I can hardly feel them on my feet. I have big feet so the larger toe box made my purchase. When running a trail I can feel every contour of the path with these while still having cushioning. The shorter height of the shoe had me worried; I figured there would be less stability, but the opposite was true. My feet easily changed angles when necessary and because of the sock like feel, my feet stayed firmly in the shoe. If you hit a patch of larger rocks in the path, you might feel them a bit more, but overall this shoe performs.
