If you’re one of the 20–30% of Americans with flat feet, meaning that when you stand straight, your arches touch the floor, you might need some more thoughtfully designed shoes. Whether or not your flat feet cause you pain, we can all agree that wearing the right shoes is vital. Slipping your feet into the wrong pair can lead to ankle, knee, hip, back, shoulder, and even neck problems, says Dan Michaels, DPM.
Flat feet also tend to be longer and wider, Dr. Michaels says. He says to look for a running sneaker with good medial arch support and insoles.
