If finding the right ski boot were this easy, then it would make the most important part of your gear selection a thousand times easier.
Finding the right boot is a matter of takinging your foot length, forefoot width, heel width, instep height, pronation, ankle flexibility, factoring in pre-existing injuries, factoring in personal tolerances for pain/discomfort/expectations of comfort, and a few other things that boot-fitters need to take into consideration and matching it all to a shell & cuff profile with different geometries and flex patterns.
As you can see, this is not something that can be answered easily or over the interweb. Your only solution is to have someone who knows what they are looking for examine your foot in the specific shell in question. Only then will you know for sure if the boot will work for you.
Anything other than that is partly a shot in the dark mixed with a large side of gamble.
