Familiarity: I've put it through the wringer
I had a pair of these for almost 4 years of moderate use.
Performance was great. They were sticky enough without sacrificing durability, they edge well for a shoe that's not too tight to hike in, they're outrageously comfortable, and the sole and upper are very wear-resistant. It's stiff in the forefoot (supportive and protective, though not extremely sensitive) and in the toebox (saved me from many stubbed toes). They can handle boulders in the V2-V3 range no problem. I'd buy them again without hesitation if it weren't for...
The sole is textured in such a way that if you walk in mud or wet dirt (pretty common in Oregon) it sticks in the forefoot area. The embedded mud doesn't come out when rubbed on, say, a friend's door mat, but once you are inside said friend's house and the mud dries it starts flaking out all over this hypothetical friend's carpet.
I wore these at Smith Rock last summer. I left them at the base of the wall while I did some climbing (they were in the shade at first, but the sun moved in at some point). After a couple of hours spent on a few routes I went to put them back on and the sole on the heel of one of them slid half an inch across the midsole as soon as I put weight on it (the glue melted) and stuck there. It was hot out, but not *that* hot. Mine was the only shoe to have this issue in our group of four. Resoling is an iffy prospect since I wore down the foam midsole some on the hike out and the following day. This may have been an extreme circumstance, but I'm still less-than-thrilled about it.
