I just dug my Vasque Velocity shoes out of the closet the other day to compare with my NB 811's, and I was kind of surprised. The Velocity's have over 1000 miles on them (from Springer to Harper's Ferry on the AT) and the 811's have around 280 miles (all of the Maine section of the AT), but the 811's look like they've been through a meat grinder compared to the Velocity's.
More specifically: the Velocity's have some scrapes and cuts on the outers over the toes, but otherwise the top of the shoes look not much different from when I got them (just dirtier). The tread is worn down almost flat in a few small spots, but for the most part it is still intact.
The 811's treads seem pretty much undamaged except for a puncture in the air-filled portion of the tread below the heel. The mesh top of the shoes, however, is fraying in several places, and the toe casing is coming apart. The mesh wearing more seems like it might be because the 811's are a lighter mesh, but the toes of the shoes just seem to have caught on roots and rocks a little harder than the velocity's.
This made me wonder what other folks' experiences are with your trail running shoes holding up over hundreds of miles of backpacking. Anybody have anything to weigh in with here?
