I would still look at the running store websites, like Road Runner, or others. They'll explain the difference between being neutral, over or under pronation. Or google it. I found this by doing that

By looking at the photos, your shoes and having someone watch you walk barefoot if necessary, you should be able to figure out which of the three you fit into. Or you may know from how you walk if you notice it. I know I can walk behind someone and know they don't have proper shoes because you can see their foot/ankle rolling in or out, or you see more wear on the inside or outside of the shoe.
The running store sites should also help explain the shoes cushioning. Road Runner uses 5 levels I think, 1 being like the natural feel, 3 being mid and 5 being the most cushy. Using their site you can help figure out what you may want to try and then see if you can find it locally or you may need to order them. I would google the shoes to see who all sells them and find one that offers free returns, if you can get that in AK. I know I have bought shoes off
Amazon when they are cheaper there.
I'm not sure how to help about the bunion issue as I'm not familiar with what you need to accommodate that. There should be information on toe box size, the rise in the heel etc. I would also look at various places for reviews because they will probably talk about the width/narrowness of the shoe etc.
Good luck finding shoes!
