Got a pair of these for work.  The sizes - for me - ran a bit small, but not too bad.  Wore these in excess of 60 hours a week, nearly all of that spent walking, climbing ladders, crawling under things and generally using them pretty hard.  For the most part, they were fine.

One point I noticed is that for bigger guys (like me) the soles are a bit thin.  After about a month, I put a pair of thin gel liners in the show, and that fixed up the sore/tender issue.  The shoe itself is sturdy enough supportive, though not excessively so.  They are also light and breathable.  Padding and isolation is good, as well.

Another point is durability.  After ten months, the shoes were beginning to fall apart.  For me, this is more or less normal; more so considering my heavy use of the shoes.  I suspect a lighter person who didn't do the kind of things I did would get more life out of them.  I still have them, but they are no longer primary shoes.  They are used when I need a pair of beater shoes that I don't mind if they get destroyed or damaged.  Most recently, I used them when pouring a new footing and patio at a friend's house in case cement got on them.

Over all, I would buy them - or pretty much any NB show - again.
