I've got a pair of NB 373's that i got about 2 years ago, and they fit me perfectly from day 1.  Bought these in the same exact size, and could NOT get them to work for me.  Something is wrong with the left shoe, or i'm going crazy.  My old ones still fit, but are just worn out.  I had to return these new ones due to the horrible fit.  They feel too tight, even if i barely lace them up.

Keep looking....
