I have almost no arch whatsoever (as well as the beginnings of bunyons). My feet are pretty narrow, as well. I usually run between 35 and 45 miles a week (the bulk of which through longer, 10+ runs). I haven't been injured in about a year (the injury wasn't running related), but I keep getting blisters on the inside of my feet and after long runs my big toes hurt. I'm probably over-pronating. I prefer lighter, more minimalist shoes because then my feet aren't so heavy, but what shoes are best for my kind of foot?
