Article on Running Shoes

I was reading some of my work newsletters and came across  a good article on running shoes.  Everyone knows you need to match the shoe to your foot right??  Well not according to some research put out by my colleagues in the Army Public Health Command as well as the other services.  I'll let the article speak for itself.  It made me think twice about my next shoe purchase.

FYI, I work for the Army Public Health Command, but as a bug expert.  

Article in the October 2010 version of Mercury:

If you want to minimize your chance of injury while running, you choose a shoe based on your foot shape, right?


Results of three military studies showed that prescribing shoes based on foot shape made no difference in the rate at which injuries occurred in Army, Marine and Air Force basic trainees, who spend quite a bit of time running.  That’s “no” as in none, sports fans.

“We found no scientific basis for choosing running shoes based on foot type,” said Dr. Bruce Jones, injury prevention program manager at Public Health Command (Provisional).  “Our findings have surprised not just military decision-makers, many of whom run to stay fit, but runners in general.”

Popular Running and sports medicine literature recommends that people with high arches should choose cushioning shoes, those with normal arches should choose stability shoes, and those with flat feet should choose motion-control shoes, Jones explained.  The literature says that such shoes will compensate for the way these foot types strike the ground during running and lessen injuries to the legs and feet.

“This seemed to many of us to make sense,” said Jones, a long-distance runner for many years.  “But when we looked at it in multiple, scientific studies, it turned out to be a sports myth.”

Jones and his colleagues were asked by the Department of Defense to test whether basic trainees suffered fewer injuries if shoes were matched to foot type in the way the literature suggested.  Experts led by Dr.  Joseph Knapik looked at more than 9,000 pairs of feet, manually measuring arch height as well as taking
Foot imprints.  In the most recent study of Marine recruits, 1,400 men and women were divided into two groups at random, with one group receiving shoes matched to their foot types and the other group (the control group) receiving stability shoes.

Like their Army and Air Force counterparts from two previous studies, the recruits with shoes prescribed according to foot type experienced the same rate of injuries as those in the control group, regardless of other demographics like age, sex, race and smoking habits (other USAPHC (Prov) studies have linked smoking to higher injury rates in basic training).

The military services are keenly interested in preventing injuries from running, and for good reason.  “Injuries are the leading health problem in the U.S. military, resulting in about two million visits to medical treatment facilities a year,” Jones said.  “Of those, more than 50 percent are lower-extremity injuries caused by weight-bearing training, and the biggest culprit is running.”

In addition to the pain and disruption the service member suffers, such injuries mean duty time lost to recovery, which in turn affects unit readiness.

Some medical experts argue that static foot morphology (what Jones and colleagues looked at in their studies) is less predictive of injuries than studying the foot in motion, but so far that theory has not been put to the scientific test.

In the meantime, what’s a runner to do?

“You can’t simply look at foot type as a basis for choosing running shoes if you want to prevent injuries,”
Jones advised.  “You should choose a shoe that you like and that feels comfortable.”

In other words, if the shoe fits
(comfortably) — wear it. (Public

Great study! Good to see some science on the problem.

I'd like to suggest you google "minimalist running shoes".

One site you might like about them:


I run all my runs shorter than 10 miles in Nike Frees. No more Achilles tendinitis!

If you are younger, running some in shoes like vibram five fingers is probably a really good idea.

Read the book "Born to Run" as well if you want a crazy story that also highlights the negative side to current running shoes.

How are you feet feeling now? Forgot to ask when we talked.
I had terrible foot pain last week from standing on a ladder. The pain didn't hit until later that night. Whew- was it ever painful! Lucky it only lasted a couple of days.

Mom, my feet have been much better since going on the meds. I still have some soreness at the back of my left hill but it seems to be getting better. The gout hasn't bothered me at all.

You have a left hill? WOW!
