This is an interesting study. However, based on my clinical
experience studying the biomechanics of running shoes, I would disagree
with the speculation as to why "full" minimalist shoes appear to be safer
than "partial" minimalist shoes. Using videography, we observe the
biomechanics of runners wearing different shoe types. What I've noticed
about partial minimalist shoes, is that the combination of a soft foam
sole and flimsy uppers causes the foot to strike a shifting interface as
it hits the ground. Such an unstable surface will inevitably cause
unnatural recruitment of foot and lower leg muscles, as the foot attempts
to stabilize itself prior to, and during, push-off. This could be the
cause of higher injury rates. Conversely, full minimalist shoes, while
less cushioned, provide the runner with a stable foot strike.
Moreover, there is - to my knowledge - very little evidence that
minimalist shoes, without specific training, cause runners to
automatically change their running style. Indeed, research has so far
shown that runners must be taught to change their form, regardless of shoe
type.
My clinical experience, though certainly anecdotal, suggests to me
that runners who have favorable foot biomechanics (arches neither too
rigid nor overpronation) and efficient running form, can transition safely
to minimalist shoes. Those with poor form or unfavorable foot structure,
will find it extremely difficult to run in minimalist shoes.
