How does forefoot running minimize impact loading on the leg? Fundamentally, it’s the forefoot-to-heel (1-3) movement path of the foot in-conjunction with the help of the calves locking in stronger ankle stability as well as helping to diffuse impact more fully, that enables the landing foot to swiftly glide onto the ground with minimal jarring force and impact amplification. This is how pounding of the feet is reduced as well as damaging rises in impact loads. Read more here about why forefoot running is more effective at reducing the risk of impact-related injury as compared with heel strike running.
