Just finished about 25mi over 2 days on the AT in these.  They look great and absorb rocks pretty well.  Not waterproof but I just picked my spots better so as not to submerge them, one section was a stream trail.  My toes were riding on top of each other by the end of my hikes though.  Got hot spots on my achilles but not a full blister, so I think they kept my foot secure.  There were many opportunities to roll my ankle on a 7mi downhill but they provided enough stability to keep my ankle from fully rolling over.  Maybe they need to make a style like the altra's with the big toe box?
