Wore a pair of these on the last 500 miles of my AT thru hike in 2010. These shoes were the most comfortable of the 4 pairs I used on the hike. Not one blister. Bought another pair just for knocking around and hiking around the home place. I did have problem with the lugs on the side of the shoes peeling off on my first pair after 2 weeks, but I finished my hike and still have the shoes. This problem did not affect anything.
