IMHO, this style of NB shoes was more than likely made for special sale promotions, to appear to be a real deal. I am glad that I did not pay anymore for them. They are nice but not worth much more than what I paid.
As to sizing, I find that any NB shoes not US made I will need a 1/2 size longer & also wider than say my 993's that I wear a 12.5 2E.
My wife also got a pair & her fit is great & she likes the shoes.
