I have Brooks. I went to a smaller running store in downtown Belmont that I highly recommend. Run/Walk is the name of it. Same as the others said, they put you in a neutral pair of shoes and video your feet as you run on a treadmill. They recommend certain shoes based on the mechanics of your feet. A little piece of advice, wear your current running shoes when you go to a store. They can look at the wear patterns and this can help them too.
