Very light weight and almost like a minimalist shoe. The knobbie soles have excellent grip in loose soil conditions as well as over rocks. Gotta shake them out good before you get in the car though, oops, but hey I'm on the dirt, so so what. Comfortable protection over most big gravels and loose rocks. Roomy toe box - nice. Very breathable and dry out quickly. Ran a 22 mile training run on technical terrain and feel comfortable with the idea of runnining in them up to a 50K. Beyond that and I will either need more conditioning or a more supportive shoe with thicker padding in the sole, but this is an excellent tool for the box.
