“Transitioning from running in traditional running shoes to minimalist running shoes should increase muscle strength of the intrinsic foot muscles. Strength of these muscles can be difficult to measure; however, increased arch height could be an effect of increased strength. Therefore, we measured arch height before and after 10 weeks of transitioning to minimalist running shoes,” said Ridge, the primary researcher. “However, our results showed no difference in arch height after the 10 weeks in either group.”
In their recent study, ten weeks of transitioning to minimalist running shoes did not cause a significant change in neutral or standing arch height, concluding that the effect of minimalist running on arch height and/or injury rates is either negligible or requires a longer exposure time for significant effects.
“Anecdotally, we often hear that runners who wore orthotics, then transitioned to barefoot or minimalist running no longer need their orthotics— suggesting that arch height has increased. Our results do not support that, but it may take longer than 10 weeks of beginning to run in minimalist running shoes before we’d see an effect on the arch height,” said Ridge.
Ridge says the study creates an opportunity for future research on this topic. Currently, there are no suggested guidelines for transitioning to minimalist running shoes (or barefoot running). In order to create safe, effective guidelines for runners, she said, a better understanding of the intrinsic foot muscles’ response to interventions is needed.
