Replying to Dalbello Krypton Rampage comparable to Full Tilt Wallicsh pro

Hi guys, well i know the whole store of go see a boot fitter, and i personally believe in that as well. But as i am in the search of new boots i have come across a problem, I live in Georgia. What that means is that there are no Nordica, Solomon Spk, or any full tilts for me to try on. The closest shop to carry these wold be 200+ miles away. But in my local ski shop they had a pair of dalbello krypton rampages. They felt pretty good in terms of flex, forward lean, and sizing. They had just given me these weird pressure points that i couldn't just get rid of. Coming from an SPK that i had bought online, they were too big (I have a 28.5 spk, and i fit a 27.5 dalabello), don't get me wrong they were comfy as hell but i just don't have a wide ass foot for them. So i ended up rubbing through my liner with all of the movement that was happening in my boot.

So after hearing my story, i have a question. Would the Krypton rampage fit the same as a full tilt wallisch pro in terms of width, size and flex. I got fitted into a 27.5 dalabello and the BSL is 316, but i noticed for the Full tilts the BSL is 310 for the 27.5. Does that mean that they fit smaller?

So final question, do the full tilts fit similar to the rampages?

Thank you! +K to helpful awnsers.
