I hated struggling with runners knee pain. I tried everything. I even ran on the treadmill instead of running outdoors thinking that the treadmill would be softer on my body. Then, I learned that it was my heel strike running style that was hurting my knees. I then discovered that forefoot running is better than heel strike running at eliminating patellofemoral pain, and here’s why.
How Foot Strike Affects Patellofemoral Pain When Running
There are two risk factors linked to patellofemoral pain in runners. They are increased patellofemoral joint reaction force and patellofemoral joint stress whereby high patellofemoral joint force and stress are associated with patellofemoral pain.
Past studies have found that forefoot running optimizes patellofemoral joint kinetics by reducing patellofomoral joint force and stress, thus forefoot runners are expected to suffer less patellofemoral pain.
Patellofemoral pain is a common problem of heel strike runners, but previous studies have found that patellofemoral joint stress and therefore patellofemoral pain decreased by 15% when heel strike runners utilized a forefoot strike landing. Why did this happen?
In forefoot running, ankle plantarflexion coupled with greater knee flexion does a better job at reducing the patellofemoral kinetics that cause patellofemoral pain.
Even more telling, Wilson et al. found that runners who utilized a forefoot strike showed a 10 – 13% reduction in patellofemoral joint kinetics per step. The study also found that patellofemoral joint kinetics per kilometer decreased by 12 – 13% when runners ran with a forefoot strike.
The take home message is that for a more optimal outcome regarding patellofemoral pain, a runner should consider refining their technique by utilizing a forefoot strike.
Humans actually have a better anatomical arrangement for forefoot running and not heel strike running which coincides with the substantially smaller rates of patellofemoral pain in habitual forefoot runners.

BSc Neurobiology; MSc Biomechanics candidate, ultra minimalist runner & founder of RunForefoot. I was a heel striker, always injured. I was inspired by the great Tirunesh Dibaba to try forefoot running. Now, I'm injury free. This is why I launched Run Forefoot, to advocate the health & performance benefits of forefoot running and to raise awareness on the dangers of heel striking, because the world needs to know.
