Got these to run a desert half marathon, in Eilat, Israel. It consisted of sand, sharp rocks, packed dirt and some boulders. These shoes are half a size bigger than the correct size, which makes me run in socks.

The shoe is incredibly lightweight, and the price is paid when running on rocks, as the tough rubber covers only patches on the sole. You do feel some rocks, but even in a half marathon, I didn't bruise because of it.

They feel great on the road. Great grip, and a great feel overall.

One last thing, they do not breath well at all, which is great in our mild winters. I can see this being terrible in the summer.
