It seems that despite the obvious, some scientists have devoted time and energy to studying the effects of wearing high heels for a long period of time.
They have come to the obvious conclusions that:
1 You should take them off every so often, and
2 Don't run in them.
As per
The New York Times:
"A new study published this month
in The International Journal of Clinical Practice, researchers at
Hanseo University in South Korea turned to a handy recruit group: young
women at the university studying to become airline attendants who were
required to wear high heels to class, since they would have to wear them
if hired by a Korean airline. With each passing year, from incoming
freshmen to seniors, the women would have one additional year of heel
wearing behind them, making it easy to track physiological changes.
So the researchers
invited 10 young women from each class to the lab and tested their
balance with a wobbly board and the strength of their ankle muscles
using computerized exercise machines.
The results were
interesting. Compared with the freshmen, who were generally new to
wearing heels, the sophomores and juniors displayed greater strength in
some of the muscles around their ankles, particularly those on the
inside and outside of the joint.
This difference
between new and experienced heel wearers suggests that “wearing high
heeled shoes may at first lead to adaptation and increased strength,” as
the ankle responds to the stresses placed upon it by the unfamiliar
shoes, says Jee Yong-Seok, a professor of exercise physiology at Hanseo
University, who led the study.
But the senior women,
who had been wearing heels the longest, showed weakening of those same
muscles, compared even with the freshmen, as well as much weaker muscles
along the front and back of the ankle and dramatically worse balance.
In fact, all of the upperclasswomen had worse balance than the freshmen, even as some of their muscles were strengthening.
What seems to have
been happening, Dr. Yong-Seok says, is that the ratio of strength
between the muscles on the sides of the ankles and those at the front
and back became increasingly unbalanced over years of wearing heels,
contributing to ankle instability and balance problems and eventually to
a decline in the strength even of those muscles that had been stronger
for awhile.
This finding is
somewhat worrisome, says Neil Cronin, a biology professor at the
University of Jyvaskyla in Finland who has studied heel wearing and
wrote the recent review of related science.
Strength imbalances in
the muscles around a joint, he says, particularly those around the
ankle, “are known to increase injury risk in other muscle groups,” such
as those in the hamstrings or upper leg.
Neither he nor Dr. Yong-Seok suggests that women eschew heels, however.
Dr. Yong-Seok does
recommend that people who often wear heels strengthen their ankles
whenever possible with simple heel lifts, for which you stand barefoot
and then rise onto your toes repeatedly; and heel drops, during which
you stand on the edge of a stair and slowly lower your heel over the
edge.
Dr. Cronin also
suggests slipping off heels while sitting at your desk, since wearing
the shoes, even when not moving “can alter the resting length of the
muscles and tendons around the ankle,” which could destabilize the joint
and increase the risk of injury.
He also strongly
advises against running in heels. The impact forces created “would be
concentrated over a small region of the foot in high heels, creating
regions of very high pressure,” he said, meaning foot pain. Plus balance
and biomechanics are compromised, making running in heels “a very
inefficient way to move.”"
In short, if you apply some common sense you will be fine.
Coming soon, a study on the effects of walking in bare feet on broken glass.
