In reply to mutt:
Not sure what Scarpa have done with the last on some of their latest boots (Jorasses Pro and Delta) but they fit me absolutely fine despite being far too wide across the forefoot.
In both cases, having fairly narrow feet, I would initially have said they were a fairly poor fit however in use they have both been superbly comfortable. At least in my case, their marketing blurb about their newer designs fitting a wider range of foot shapes seems to hold true.
YMMV but I thought it worth mentioning the fact that on my B3s especially I found the exact width fitting at the front of the boot fairly irrelevant to overall performance.
