Never worn Montrails, but people seem to think these fit narrow feet well, and that sounds just about right to me... Width aside, do they run true to size?
Montrails run true to size - I've had about 5 pairs of Montrails and never had to adjust sizes.
Montrails typically fit true to size. This may be illusory, but myself and a few friends have noticed inconsistency in sizing since the Columbia buyout (Chinese manufacturing?). I have had 2 pair feel like a half size smaller and thus returned for a replacement pair. The replacements were fine and felt true to size. In my opinion, Montrails are great for gnarly, long days requiring ALOT of shoe. No question they have their place!
