Shin tendon pain, especially on the inner part of the lower leg, is extremely common in joggers who heel strike. One of the easiest ways to prevent running related-shin problems is with forefoot running. However, many newly transitioned forefoot runners still struggle with medial shin pain. In this case, a narrow step width or a crossover running gait is the culprit.
Why Some Forefoot Runners Have Shin Tendon Pain
A study by Meardon and Derrick (2014) investigated the effects of step width manipulation on tibial strain in runners (step width is the distance between the feet during successive foot strikes). The runners were given a verbal cue to run with a narrower or wider step width, both of which were to be 5% more than their preferred step width.
The result: running step width influences medial tibia tension at touchdown whereby a wider step width reduces medial compression and tissue loads as compared with crossover running. Interestingly, a wider step width also reduced normal stress loads and reduced lower anterior tension as well as posterior and medial tibial compression.
By comparison, a smaller running step width has been linked to greater pronation, hip adduction and knee internal rotation, which increases the medial-lateral ground reaction force, torsional loading and tibia strain — all are implicated in tibial stress fracture progression in runners.
The trick to avoiding these adverse reactions when forefoot running is by making the new effort of opening up your step width, making sure your feet land farther apart. And remember, a narrow running step width is not the only culprit in chronic shin pain. Cushioned running shoes, for example, enable a runner to land hard on the ground, causing more widespread impact to the leg. Barefoot running shoes promote ‘lighter’ interactions with the ground, not to mention running barefoot is even better at reducing musculoskeletal loading.
Nonetheless, a great way a forefoot runner can widen their step width is to run over top of the line on the side of the road, making sure your feet land on either side, not on or near the line, but rather your running step width should equal the width of your hip. Hope this helps!

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.
