Heel vs midfoot strike

Stop 1/3

脚跟 vs 中前掌落地

The classic Lieberman 2010 *Nature* study found that habitual barefoot or minimal-shoe runners are mostly forefoot strikers, while about 75% of runners in modern cushioned shoes are rearfoot strikers.

Lieberman's hypothesis: modern cushioning makes heel-strike painless, but the initial impact transient at ground contact is 2–3× higher than for forefoot strikes, possibly linked to running injuries.

Follow-up RCT evidence, point by point:

Hamill 2014 review: strike pattern has no strong correlation with injury rate; individual variability + training volume are larger factorsHasegawa 2007 half-marathon finish-line observation: 75% of elites are also heel-strikers — even elites don't have to forefoot-strikeEsculier 2018 *Br J Sports Med*: forced strike-pattern change is equivalent to rebuilding the entire running gait; injury risk during the transition rises ~50%
Implication: don't change because 'Lieberman said forefoot is better'. People who are already running injury-free should not switch — 'fixing what isn't broken' is a major injury cause. If you do switch, give yourself 6–12 months of gradual transition.
