Comments: Bought these shoes for a 25k race on a notoriously muddy trail. They have great grip on any soft surface, including mud! Most shoes I wear an 11 to get extra width and toe room, but bought these in 10.5 4E and the fit is great for my wide feet. Lacing allows me to really lock in the heel and midfoot while keeping room in the toes. I didn't like the soft insoles, so I removed them and instead use the insoles from my Inov-8 Trailrocs, but that's just my personal preference for a firmer feel under foot. Pictures make them look stiff, but they are quite flexible. I don't have a lot of miles on them yet, but so far they are holding up really well. They don't grip smooth surfaces well, I had to be very careful on the wet wood bridges, but that's not what they were made for and a small price to pay for the positive qualities of this shoe.

Comments: The NB Zero Trail 2 is very durable, and the tread is amazing. I run on extremely rocky terrain and these things grip like no other. They are also great for a mid-run boulder scramble if you feel like getting a little wild. Zero drop and soft-ish feel make my knees happy. I have 350 miles on a pair; while the tread is worn a bit where I strike, there is no other wear visible on the upper or bottom. No tears or anything. When I wash them, they look new. Cons: the ankle opening is too big and allows rocks in; and the last is too narrow on the forefoot. If NB made this shoe on the Minimus last, they would have an Altra killer all the way. NB if you're listening--a blend of the MT110v1 last and the Zero Trail 2 upper/tread would be the best shoe ever.

Comments: The Zero V2s are the shark-toothed, trail grabbing, smooth riding superbly designed shoes I hoped they would be. The outsole is fantastically grippy. It sticks almost miraculously to gnarled rocks, scree, loose dirt, grass, and everything in between. Due to the tall tread, things can get a bit tippy/inversiony when running at extremely fast paces straight down a steep and irregular rocky surface, but in general everything flexes just right and you plant predictably. The lack of a rock plate was a very good design choice. Your foot can actually move with the shoe, and you don't get that awful rigidity and deadness. The tread does plenty to protect you. The midsole is responsive and tuned just right in terms of firmness and responsiveness. The upper is a bit homely and retro, but it buttons you down firmly, breathes very well, and melds nicely into your foot. I do wish these had 4mm of drop, but hey, that's what the 110V2 will be for. In the meantime, if you want a fa st trail carver look no further.
