I got these shoes to replace my worn-out Asics GT-2150s, and so far I'm very happy with them. I actually like them better than my Asics.

One particularly noticeable aspect of these shoes is that they're very lightweight and somewhat narrow. Might not be good for those with wide feet, but I love how they fit. They also have more curve on the front sole than I've seen in a lot of shoes. This, combined with the excellent traction the sole structure provides (around 20 raised horizontal bars), has been great for forefoot running.

So far they've held up well to both trail running and road/sidewalk running. I've heard some people have problems with the height of the shoe at the ankle, but I haven't experienced this. Putting them alongside my Asics, I don't notice any difference in that area.
