What are flat feet?
Having flat feet is different to pronation, or overpronation. Pronation is a normal movement of the foot which occurs just after the heel touches the ground when walking. This means that the foot rolls inwards and arch lowers, to allow the foot to mould to the surface and to absorb shocks. Over-pronation is where too much pronation occurs, or it occurs too rapidly, which places additional stresses on the ankle, knee, hip and lower back. A flat foot is usually evident from observing the foot, whereas someone who overpronate’s may have a normal arch when standing still, which flattens excessively whilst walking or running.
