I've run a few 50ks, 3 - 50 milers, 1 - 100 miler, and 16 (I think) road and trail marathons and I have done them in all kinds of shoes.  So I have no allegiances to any shoe brands.  I went to Roadrunner to try out some newer trail shoes to replace my trusty NB100s that have served me well over the years.  What I liked about the NB100 was the light weight and low profile soles.  It's very minimalist and I liked that.  But it was a bit narrow and sometimes it would chafe in the back.

I tried the montrail in the store and liked that it was lightweight and had a pretty neutral sole with good padding.  I always wear a size 11 so that's what I got and it felt ok in the store.  Fast forward to my first run on trail.  BAD.  It was too small and my big toe got jammed pretty good.  Roadrunner was good about exchanging it to a bigger size and I got 11.5.  I tried running in it and it was much better but I found that the uppers were too squishy and my forefoot tended to slide side to side a bit more than I liked.  I tried to tie the laces really tight but it didn't help enough.  Also, the NB100 had a hard plastic plate that ran through the bottom sole that protected the feet well.  The Montrail Rogue has a thicker foam sole but it didn't have a similar hard plate so some of the sharper points tended to put a pressure point on your feet.

All in all, I haven't done more than 10 miles at a time in them so I'm not sure if the softer foam will pay off on longer runs or not.  I have a 50k race next weekend so I will find out how they perform and report back.
