I've always been flat-footed as a kid, but recently, I've endured 3 cortisone shoes for plantar fasciitis as well as an accessory navicular in both ankles.  I've tried a variety of orthodics including prescriptions.  Either I have to drop 70 lbs or face flat-foot reconstructive surgery.  Of all the shoes and orthodics I've tried, these ASICS are the only ones that have supported my flat feet.  No pain during workouts.  I just wish I could get these shoes in other colors so I can wear them to work.  Other than that, these shoes will help me reach my weight loss goal and avoid expensive foot surgery.  I highly recommend them!
