I've used LOTS of minimalist trail runners. If I had to throw out my favorites
If your looking for something similar to the MT101 i'd say the merell mixmaster is a pretty good shoe to compare it to. It's slightly heavier, but has a more flexible sole, and more durable shoe overall without a huge weight penalty.
Similarly the Altra superior would fit the bill and is now my ALL TIME FAVORITE HIKING SHOE. I've been using this shoe for the past 4 months for hiking and think it's the ideal hiking shoe. Wide toebox, durable upper, comfortable protection for rocks, grippy, and tough. and they look good!
Merell Trail Glove - Super minimal, yet an awesome shoe. I think this is as minimalist as I'd be willing to go for a hiking shoe. I ran a 30 miler in them and my body really felt it. It's an excellent shoe but as with the inov8's durability is an issue.
I really like inov8's a lot. I use the flite195 daily for road running, but would not want to hike in many of their shoes. When I thru hiked in 2008 i destroyed a pair of inov8's fairly quickly and was a little disappointed with their overall durability. With these shoes I've also found that for better or worse they have a lot of ground feel. Which is a good and bad thing depending on the terrain. I think that other than durability inov8 makes excellent shoes.
