I don't mean walking into your nearest New Balance dealer and having them help you pick out a shoe through trial and error. I'm thinking specifically a kind of store that will analyze your gait, take into consideration any physical needs (such as a bad knee), as well as what you'd be using the shoe for (cross training vs running on a track, for example.) I used to live in Boston and they had a store like this. They actually videotaped your feet on a treadmill in order to analyze your way of walking and what shoe would be best for your gait and activity. Any suggestions??? I should add that I am looking for a shoe that is VERY supportive (I often have hip and lower back pain) and can be used for running/jogging and all gym activity.
