great fitting shoe, but not durable. 1st pair 160 miles blown out mesh just beside the big toe both shoes. Thought it might be a fluke so bought another pair, 2nd pair 140 miles blown out same place. Thought it might be just me, nope, buddy on same day blew out his. Had this problem years ago on the masai and melee(spelling is probably wrong) by montrail. I think a little more r&d with the materials could make this a great shoe.
