Kevin Christian wrote a review of Montrail Mountain Masochist WB Trail Running Shoe - Men's on September 6, 2012
I mainly use these for hiking as I don't like hiking boots. They are fantastic. Great traction, great comfort and cushioning. I have done a little running in them and they seem fine, but I prefer my lighter Rockridge shoes for that. I'm a huge Montrail fan and the Masochists are working great so far. I haven't used them long enough to determine durability.
