I'm a 5mm shell fit in my Ascendant SC's, and I have a 105+mm forefoot and high instep. The ankle area is a little big. The patriot thing works great on my 50+ day packed out ass intuitions to get me through the rest of the season, but I'll be back in ZipFits next season, 100%. Spending $500 at the end of the season vs. $40 was a no brainier, and they do the trick!
For people who are new to skiing, get used or past season boots to save money, or don't know what the hell size their feet are, this could be a good solution until they can see a proper bootfitter. For some, who don't know if skiing will "click" with them, don't get out many days a year, or are just learning, can't justify or afford buying new boots and getting boot work done with a fitter, this is also a good solution. and it can seem pretty intimidating.
Mostly, those types of folks won't even know if their boot fits like trash until they start getting better at skiing and begin to experience pain and issues as a result of terrible fit.
Obviously going to a boot fitter is always the first and correct answer
I'm fuckin baked rn
