 If you think about it, the feet are the base to your whole body. That's why she suggests personally fit arch supports. Emphasis on the personal fit. If you get something basing it just on your shoe size, it isn't going to fit you properly. And if it doesn't fit well, it probably won't work well. Go get arch supports fitted to you. It's as easy as going into a Goodfeet store. The Goodfeet store has locations across greater D.C. and Baltimore. Visit goodfeet.com to book your appointment today or just stop by.
