I have a long, narrow, low volume foot. The width and volume of these boots is great for a foot like mine. I got the B width, and it's really great size-wise.

The boot upper needs a lot of breaking in to get it to form to your ankle area.  After wearing this boot awhile, I still get discomfort from the upper.  The monogusseted tongue - where it tucks in the boot around the outside of your ankle can be very uncomfortable if it does not fit with your ankle well.  For me, the outer edge of the tongue presses against the front side of my ankle bone.  Hopefully that will continue to break-in over time.

For me, the volume and narrowness of the boot is great.  The Vibram sole is very good.  It's a relatively soft rubber, so it grips well (although that means it will wear faster).

For those who had/have the Dunham Waffle Stomper boot (no longer produced), this boot is not that good.

This boot is more substantial than fiber-type hiking boots, but less substantial than leather boots.

Ankle support is surprisingly good in this boot.

Lacing system is ok....

The rand around the outside of the boot is excellent -- especially for those who get all sorts of nicks and cuts on their leather boots around the outside and toe.

This boot does have some nice qualities.  But I would encourage prospective purchasers to purchase them in a way that they can be tried on and returned if the monogusseted tongue or width does not work for you.

I've had other boots I've liked better, and I've had some that were not as good.  This is a respectable but not fantastic boot.  I hope that NB produces something similar but better in the future.
