[1] Barefoot running: How humans ran comfortably and safely before the invention of shoes

[2] Participants performed better on a working memory test when running barefoot compared to shod, but only when they had to step on targets

[3] Twelve weeks of barefoot running, applied progressively, causes significant changes in foot strike pattern with a tendency toward midfoot or forefoot strikes, regardless of running speed and significant changes in foot rotation at low speed, while the inversion was reduced in left foot at low speed with a tendency toward centered strike.
