When I first ran in this shoe I loved the feel and the super lightness. Now after a couple of hundred miles in it I am even happier. Very light. It is wearing very well and evenly. The sole is soft so you feel an intimate contact with the trail. The downside of that is that you notice the sharp rocks more, but I expected worse from such a light shoe. It is incredibly comfortable and very stable. For me, it is not the ideal shoe for long miles on very technical trails (I'll stay with the La Sportiva Raptor for that), but I have run distances up to 50K and felt great. Compared to the La Sportiva Quantum (which was a huge disappointment to me!), this shoe is lighter, has way better traction, more stable, and a much more comfortable fit. Lives up to all the hype.
