I've been running trails seriously for a few years and have just signed up for a 100k in the German Alps. Having run with the 3 pairs of the non-Goretex version of this shoe in 2 years, I decided to grab these for winter training in soggy ole Germany. These fit almost exactly like the non-gore version though they don't wrap and snug around the foot. There are slight modifications to the pull tabs which can get folded onto your achilles if you aren't careful putting them on. Otherwise, the large lugs give great grip in the mud, but the rubber on these sticks well when navigating rocky terrain. The shank is stiff enough to dampen the sharp limestone edges we run over, but still leaves flex in the foot which gives good trail feel. I have put a couple hundred miles on these, and I have been worried from the start about the durability of the zipper, but it has yet to fail.
All in all this is the best trail runner I have used when compared with some Montrail (Hardrock, Masochist) and New Balance (MT 100 (but I dont run minimalist anymore).
These definately seem geared towards a narrower foot.
