Not for harsh rocky terrain
"I used these for the length of the JMT and by the completion, the left shoe sole near the toe had already started to fail. But it seemed that they had some life in them. After 80 miles on the AT in NJ and into NY, they utterly failed and I had to stop that hike midway through. 320 miles total. That's more what I expect from a trail runner. I would only recommend for hiking that does not include trails of this type."
