OTIS, I have the same problem, and its been a pain in the ass for a long time. Flat feet cause all kinds of problems in the legs and lower back, I got a pair of custom orthodics insoles for my shoes and sneakers and it helps tremendously.

I got mine through my chiropractor, and they were not cheap, like 800 per pair, but with insurance I think I paid 40 bucks or something like that. You may want to look into it.
