There’s a long list of reasons forefoot running may be better than heel strike running. One major reason is there’s less all-around impact forces acting on the body. For example, forefoot running naturally minimizes a harmful force called the jolt or jerk force by naturally reducing an extended leg and enables greater knee bend and flexion at touchdown. This better positions the landing foot closer to the center of mass (upper body) which was found to effectively reduce brake force duration, meaning the body decelerates much less during the first half of stance, also resulting in far less jolt on the joints. Read more here on why forefoot running may be better for injury prevention than heel strike running.
