The foot rolls inward about fifteen percent, comes in complete contact with the ground, and can support your body weight without any problem.lthough pronation is a natural movement of the foot, the size of the runner's arch can affect its ability to roll, causing either supination (underpronation) or overpronation. If you have a normal arch, you're likely a normal pronator, meaning you'll do best in a stability shoe that offers moderate pronation control.
