When it comes to how flat feet affect running, the main area of focus needs to be on a biomechanical process known as pronation. This refers to the distribution of the force load that comes with taking every step. When the foot pronates normally, it performs a roughly fifteen percent inwards rolling motion. However, individuals with flat feet do not have the same level of support from their foot arches, thus the inward roll is greater, which is called overpronation.
Individuals who overpronate place greater pressure on the inner edge of the feet. This can lead to an increased risk for sports injuries like shin splints and tendonitis in the knee, and pain in the feet, ankles, legs, hips, and back.
Generally, overpronation is not a major issue for walking, but if you have flat feet and enjoy running, you might benefit from motion-control shoes, arch support inserts, or custom orthotic devices.
