Just thought I'd ask what other folks experiences have been regarding durability. I've put about 300 miles on mine (about 190 of those have been ultra races) and while they've been comfy and grippy, the uppers are beginning to fall apart.
Yes, they have had a hard(ish) life but they seem to be faring worse than my normal trail shoes. Perhaps no big surprised considering the price but I usually get at least 500 miles out of trial shoes.
