there's chain here called "feet first" (probably national or at least something similar where you are) where they help you pick a specific shoe for you foot and how you walk/run. i think they can be a bit pricey and i don't think you get much selection in terms of what you like best in colour for what works best for your foot, but if you're looking for a good shoe places like these come highly recommended. i've always heard bad things about nike for actual running shoes, but i don't work out so all my information is hearsay...
