I'm a trouble case for fit - narrow, low-volume, Morton's Toe, etc. Since New Balance stopped making trail runners in narrow I've been looking for trail running shoes that even sort of fit. These are the ones. A good low-volume fit, relatively little lift at the heel so the foot position is neutral. They're new, so don't know yet about the durability. The soles have incredible traction on rock, and the low-profile tread pattern gives good grip in loose surfaces while not catching on stuff like deep treads sometimes can. I hope they never stop making these.
