What kind of fit are you looking for. I have had both on and couldnt tell any significant differences. Why the 80 though? Isnt that a really soft version of the 106 or whatever it is? Or are you looking at the plug? I have only tried the retail boots, and i found them to be very soft. This years race boot has a higher volume race fot than most race boots i have tried on, but it maintains its comfort and a soft almost elastic flex. I actually almost bought this years head WC boot to free ski in, but based on forefoot volume, went with the S12 instead. The S12 with the narrower last in it really has a race type fit, but has a few extra comfort features that race boots dont offer.
