Hmmm. That's a tough one as I've had three pairs of scarpas over the years and all three were different sizes (40,41&42) so I've not found their sizing to be all that consistent. Yes the zamberlans are the narrowest but they are fine on my foot (fairly normal). Ill measure the inner sole lengths and also weigh both pairs for you

Edit: both are identical 26cm (which works as Im a 9). Where the difference in fit is the Zamberlans have a narrow but tall toe box that doesn't taper till the end vs the the new balance are wide enough at the metatarsal head, though taper earlier at the toes. The NB fit me fine length wise for day in day out, but sliding forward on a down hill id prefer that extra half a size in the toes as I catch my pinky toe (hope that explains it).
As for weight the Zamberlans are 1100g for the pair and the NB are 820g on my little scales.

Hmm. The photos don't show it well but its more distinct when looking at them.
Either way id be happy to accept a return if you weren't happy. Im sure they'll sell eventually
