I've been a longtime fan of New Balance's entire trail line, from the beginning of the MT series (100,101,110) and the Minimus series (both road and trail).
I've been very happy with my MT110s overall. In fact, I blame a recent knee injury in the Grand Canyon partially on not running in them.
Anyhow, I had a pretty big failure the other day:
I was on an easy 4 mile trail run and caught the upper on a stick during a stream crossing. Riiiiipppp. Total failure. Bummer because I really can't afford new shoes right now. These shoes use a perforated plastic upper instead of fabric. What I originally thought would be a very durable upper turns out to rip catastrophically under certain circumstances. I saw the exact same thing happen to a pair of Adan Lopez's on their very first day out. Joe Grant just had a similar, though worse, failure with them.
While this perforated plastic stays very clean and is very durable vs. water, abrasion, and general wear, not so against tears.
Just got off the phone with NB customer service, simply wanting to report the issue to them. Despite my shoes having hundreds of miles on them, they're taking them back and sending me a free pair of whatever I want. Very standup customer service, totally wasn't expecting a new pair of shoes given the miles I've put on them.
I like these enough that I'm going to try another pair, hoping for better luck this time
Just wanted to share the experience with their customer service; very cool to deal with. I've always liked their shoes, now I have another reason to stick with them.
