Does it exist? What's your favorite? I have high arches, I walk on my heels (which causes a lot of heel pain), I have bad knees, and just overall small finicky feet. I want something I can walk, run, exercise, do whatever in without foot/knee pain. I want something that is especially good on my heels. It doesn't have to be pretty, but it can't be bulky (because they look funny on my small frame). Lightweight would be good. No pink. Also, must be a brand that goes down to a size 5 or 5.5. Anyone tried Nike Shox? They look like they'd better ok on my heels, but I don't want to blow my money if they suck. So what shoe works best for you? Oh yeah, edited to add: I try on shoes in the store and they are so comfortable and then after a week they make my feet hurt. So unfortunately, I can't just go to a store and see what feels good.
