It’s not often that a home run is hit at the first at bat, but Keen’s first attempt at a trail running shoe has accomplished this feat. We have been training and racing this year in their Ochoco trail shoe. The Micromesh and synthetic upper allows air to flow freely for a dry interior. Heel stabilizer keeps a firm hold on the foot for safe travel. EVA insole is anatomically contoured to naturally support your adventurous sole. Roomy toe box. No blisters, no black nails- even straight out of the box. They do run a little small, so I would order 1/2 size larger than normal.
