Comfortable, but falls apart - I recently purchased the North Face Men?s Betasso. I have worn the shoes for about a month and a half and the sole of the shoe is falling apart. There is an oval looking piece on the bottom of the shoe that is under the heel that is falling off on both shoes. I work as a backpacking guide in New Mexico so I need shoes that will hold up. These are comfortable for shorter less rugged hikes, but going over rocky terrain/long distances (15 miles+) in a day they can become uncomfortable. Most of all though, they just don't last.
