Ran a 35km and 42km trail runs over the past  week. Put the solomons on right out of the box. No hot spots or blisters. The grip is excellent and the shoes don't pick up mus on the bottom. The cushioning is perfect, as some shoes actually put to much. When running between two trails there was a spot where I ran on the pavement for 5km. These shoes aren't designed for road running and I could feel the rubber cleat on the bottom. Will buy again.
