I've had several other pairs of Montrails that served me well, but they appear to be having quality problems now.  I noticed the outer sole at the toe separating just a bit several weeks ago, and the outer sole came off on a hike a few days ago.  They were less than three months old when it happened and had under 50 running miles (mostly road) and under 20 hiking miles on them.  I hope this isn't a sign of where Montrail is going, because I've really liked my other shoes from them.  UPDATE: I sent the shoes back to Montrail six weeks ago for warranty repair/replacement.  (The outsole separated outside the Amazon return period but well within Montrail's one-year warranty period.)  I've heard nothing from Montrail since returning them, and they haven't responded to a follow-up e-mail I sent five days ago.  Not sure what's going on with Montrail, but they've lost my trust.
