An 80 mile runner, these are the first Brooks shoes I've bought in years. I was hoping to use them as training shoes for 800m-3200m intervals and they did not disappoint! I even ran a 7 mile marathon workout with them and they held up great. The shoes are durable but the feet don't touch the pavement. Very light and fast. I would never use them as a hiking/everyday shoe but they can handle workouts and the occasional fast long run.
