i have put over 300 miles on my CV's. Both on the road and the trails. The Good - not a single sign of tear and grip has held up. As others have stated, I have never got a blister and they are super comfortable. I also run in Saucony and Salomon, and these are superior in comfort to those. The Bad - They are a bit difficult when extremely wet and / or muddy compared to aforementioned shoes. My final comment is that compared to other trail shoes they are not as firm in terms of a rock plate, so if you are running heavily technical trials, these may be not as forgiving if you hit something big.
Otherwise, solid shoe. I will buy more, especially for California and / or NW races.
