Danner says they engineered the Campo 2650 hikers with a southern section of the Pacific Crest Trail in mind. Campo, California, is an arid desert town that many PCT thruhikers will know well, and which gave the shoes their name. After months of wear, rubbing up against rocks, roots, thorns, ticks, dogs, bike pedals, you name it, the uppers are fine. The soles are Vibram Megagrip, giving all sorts of confidence on rocks, roots, scree, and, yes, bike pedals. They have an 8mm drop, pretty mellow for a trail shoe.
