Wore these for the first time today and they felt great for the 12 hours I had them on.  No breaking in period.  Like the color and the suede too, although if they offered them in white and/or black, I'd probably buy those too (that's how comfortable they are).  They do run about a half size short and little bit narrow.  I normally wear a 5B to 5-1/2B but got these in a 6B and they fit great.  Based on my experience, I've found that several of the New Balance styles seem to run a little small compared to other brands (I also have NB cross-trainers in a size 6).  If you want to wear heavier socks with these, I'd definitely recommend going up a half size from what you normally wear.
