A running store will sell unfashionable items and not be ashamed to do so. Think lycra for guys and so on. It's like the polar opposite of your average sports store.
I wouldn't recommend going for Asics blind, as Asics make running shoes for all different running styles. You might get what could be classed as an amazing pair in reviews and whatnot, but for you they'd be all wrong. Having said that, my last pair were Asics, and they were excellent. Unfortunately, when the cushioning went on them, it went really quickly so they're now useless. I moved over to a pair of Nike Zoom Triax, and they're excellent for me, but they may be rubbish for anyone else that doesn't flail their legs like I do.
You really need to get a gait analysis by a proper running shop staffed by runners, as opposed to your average fashion sports store staffed by 16 year olds with zero experience or product knowledge. Don't expect to get something that looks good, in fact I've found that the performance of a running shoe is inversely proportional to how it looks (my last two pairs have been bright yellow!!)
