I think a big part of it is individuality. All through my years running track in college, I would put 1500+ miles on every pair of road running shoes I owned. My record was just over 3000 before I finally wore through the sole completely...
I have to say, the best pair of trail running shoes that I have encountered have been the Altra Lone Peaks. They are a zero drop shoe, but not exactly minimalist as they do have a solid amount of cushioning. Regular reviews place the life of the shoes at ~1,000 miles, mine are currently at nearly 900 and have a lot of life left in them.
I love my Salomon shoes that I have owned through the years, but the durability is always questionable. Well made and insanely comfortable, no doubt, but they always seem to fail much sooner than other brands.
Seriously, try the Altra Lone Peaks, you won't regret it.
