I've been wearing my NB 890 v1 it is one of my favorite shoes in the rotation even though they had their weakness, mostly just a fast wearing tread and the aggressive toe drop. The only thing I can say I wish was that the tread was designed a little better.  Since the v1s are at the point I shouldn't run in them anymore I ordered the v2s after seeing they improved the tread.

I got the shoes and they fit snugger and the toebox is just a bit snugger as well. However, I ran in them a couple times for 6 miles each time and I can say there are things that are great and some things I wish were a little different. Tirstly they are light and NB improved the treads on 890s, thank you! On the other hand, they fit like they are a half size smaller in width and the aggressive taper towards the big toe has my big toe rubbing against the shoe pretty good. After a few long runs they are starting to break in but they are snug, however I ran about 5 minutes faster immediately on my 10k runs so I can't complain.

They fit a little snug, but I'm sure I'll get used to them as they don't cause any blisters, encourage a neutral gate, and by the time I've worn through the treads a bit, I'll probably get a second pair to rotate in.
