Is it Bad to Heel Strike When Running?

Unfortunately, the farther back you land on your heel, the more the front of your foot lifts up (increased dorsiflexion), the more the knee-joint extends and straightens out. The big problem here is the foot ends up wrestling too much with the ground (i.e. low cadence) and pushes the foot outside its neutral range of tolerance as compared with forefoot running, which naturally minimizes ground-contact time (i.e. higher cadence). Read more here about why heel strike running is the most damaging style of running and why forefoot running will always be the safer way to run!
