answer:Your feet, when you are born, do not need arch support. Your feet, if you were born with no defects in them, are born exactly the way they’re supposed to be. If you never put on shoes, you would continue to not need arch support. But the wearing of shoes our entire lives causes the need for arch support and all that other hooey. But naturally, our feet are designed to be exactly the way they are. Flat, relatively thin soles are more like walking on regular ground, which is what Chucks are. Unlike flip-flops for example, which cause your feet to grip the shoe with your toes, desipite the thin, flat sole.
