The shoes are true to their sizing and comfort. My problems are not with the exterior durability but the interior. The outside of the shoe has take the wear very well and the vibram outer soles are are outstanding in any condition. Unfortunately that durability and comfort does not follow on the internals of the shoe. I the inner sole and tongue have held up but the area around the the bottom and top of the heels in both shoes have just fallen to bits. The tab on the back of the right shoe tore off with a slight tug. All of this from just pedestrian traffic on a dirt/rock road and sidewalks. Sadly this is not an isolated case as one of my colleagues Merrell's have done the same thing over a similar time line. If someone knows of a better shoe with the Merrell line I might buy again but for now this is my last pair.
