Biomechanics of Barefoot Running (Brad Makimaa, DPM)

A few things are missing from Dr. Makimaa's
rational. First, he does not mention that the
runners "length of leg", which is of course
determined by the runner's height, has to be
taken into account.

Second, after we take into account the affects
this has on stride length, we must then look at
the runner's chosen stride length, and determine
if the runner is under or over striding, for the
speed they are running.

Third, is limited dorsiflexion of the hallux a
factor in a runner's stride length? Heel strikers
can have a longer stride. Forefoot runners must
pull up short, unless they are sprinting. The
thickness of the forefoot in the chosen shoe,
affects limb length.

Dr. Makimaa referenced his "rigid" orthotics,
which makes me want to know just how rigid; What
material, in what thickness, for how much body
weight? The Asics Tri Noosa 8 is not a stability
shoe according to Asics, which lists the Gel-
Noosa Tri 8 as a neutral shoe, i.e., cushioned,
which might be okay for forefoot strikers, if
they run the whole race only striking only their
forefoot.

For my patients who are recreational runners,
running to stay fit and feel good, I have a rule
(Robert's Rule); Don't let ego allow you to do
something stupid! Run in such a manner that
you'll be able to continue to run for years to
come. I explain that the "rubber" between their
foot and the road, is insurance to protect from
injury. For the elite runners, each and every one
has very different needs that need to be
addressed.

To be blunt, beyond ego, I see no rational reason
to risk the injuries inherent in barefoot or
minimalist running, unless you are one of those
rare human being who has perfect biomechanics and
perfect form.
