Heel strike running is bad because multiple lines of research over the last few decades have proved the many verifiable aspects of heel strike running that are primarily responsible for nearly all running injuries vs forefoot running.
Why Are My Feet Tired After Running?
One of the main causes of tired feet after running is foot strike pattern. It turns out, how you land on your foot when you run has big implications for your foot’s energetics, whereby heel strike running was found to cause more rigid, high impact landings, while the line of travel of the foot when interacting on the ground was found to undergo a more harmful line of trajectory, tied to more over-pronation (i.e. the heel is forced into extreme positions) as compared with forefoot running, which was found to make more efficient, yet passive use of the foot. All in all, heel strike running causes the foot to grapple too much with the ground, which was found to be both inefficient and ineffective from an economical and injury preventative standpoint.
