I'll be honest, it very difficult to make a precise recommendation if you're currently in a shoe that's too short, too narrow, too shallow and we don't know the size that has been recommended to you, or your current shoe size. If you feel it's not too much an invasion of privacy, posting the scan data (if it was done on a scanning machine rather than just a verbal opinion) would be a starting point.
I'm not trying to pooh-pooh your question, but nobody on this page is gonna be able to accurately tell you:
Based on the information we have to go on so far, hence why I suggested that if you can go to a store. As it sounds like your trip to Pure Hockey didn't solve the issues, I think it's worth either trying a different store or different personnel. One thing I've learned is that you do sometimes have to ask the right questions at a store. If you tell the staff that you have arch pain, then they'll give you a footbed, as that's the default solution for that problem in isolation. However if you're experiencing (at a guess) pain throughout the foot due to a combination of the foot being crushed from all directions, as well as possibly blood flow problems from having your feet escaping out the top of the tongues, way over the eyelets, then a footbed wouldn't solve these problems.
The Vapor (pre-FIT system) boot size is the shallowest and narrowest on the market, at least in bauer's catalogue. If you can't get into a store where you are (all non-essential retail is closed where I am as it has been on and off for the past 12 months), I would suggest finding a store that lets you return unsharpened skates/unworn rollers, and just buy a pair that are in the recommended size/width that you've been given when at the shop, with the intent of returning them after lacing up (maybe baking) and just sitting in them for an hour or two. See if any of the pain shows up, make a note of it, and send them back. That way, you can either ask here with more info, or return to the shop and ask more specific questions, getting more specific answers.
Vapors a size too small hurt
Is a good start, but if you can then add to that with, for example:
Tacks in an 8EE feel alright but heel doesn't sit right
Supreme in Fit 2 still makes arches hurt
Nexus D/EE skates (if you can find any) are like swimming in a shoe
THAT will be much more useful for narrowing down recommendations.
