View reader, Travis, asks,
"Doug,
I was hoping to email you, but I couldn't find a link for your address.
My question for you is about the new running book, "Born To Run". The
book's thesis focuses on whether our bodies were in fact made to run.
One part of the premise focuses on the benefits of barefoot
running. In short, our feet "atrophy" in shoes similar to the way our
arm would in a cast. It goes on to say that many of our injuries would
go away if we ran barefoot or with minimal support and not the high tech cushion shoes. I was curious to hear your opinions.
I'm an avid read of your blog so I hold your opinion in very high regard."

Thanks Travis for your question. And, here's the thing about email. If you email me and I answer you, I answer it here so all the readers benefit from your question. Submitting a comment like you did is the best thing to do anyway. Sometimes it takes a while for me to respond to a question especially if it involves research as in this case. I had to try my ideas first.
Barefoot running is a hot topic right now although the idea has been around for a while. Ken Saxton has run 38 marathons barefoot and has developed quite a tribe of barefoot runners. And barefoot running is not just for runners who love a fad and jog around a golf course. Ethiopia's Abebe Bikila won the Olympic gold medal in 1960 in world record time of 2:15:15 - barefoot.
Your question is a good one, not just for barefoot running, but for a larger issue of culturally induced atrophy. Many people lead sedentary lives and as a result muscles, tendons, bones, cartilage and other biologic tissues atrophy. This creates a narrow window of physical capacity or reserve. So, when we are faced with some new physical demand, like spending four hours on a Saturday morning in the yard raking, digging, planting, etc., we end up injured. Instead of changing our lifestyle from sedentary to active or even athletic, we seek solutions to eliminate the pain and remain sedentary.
But, back to barefoot running. First, to run barefoot means running with different mechanics than what most people use. Some runners follow the Pose method of running or Chi Running both of which promote using gravity to propel the body and using the forefoot for ground contact. The idea is to keep the stride short, increase the frequency of leg motion, lean forward, and keep your foot under you instead of reaching out in front for a long stride. Both sites
have quite of bit of learning material for a beginner.
But, running barefoot is tough on your foot, of course, unless you can run on grass or a sandy beach. My first choice was a pair of Nike Free shoes. And, compared to a regular running shoe, the Nike Free did alter my running mechanics although you can still land on your heel. The shoes are light but it doesn't feel like you're running barefoot.
My next choice was a pair of Vibram Five Fingers. Vibram's are like a glove for your foot. Running
in these completely changes the way you run and feels very much like running barefoot. I started with about 400 meters of running and 400 meters of walking. The muscular work in the foot and lower leg is significantly different than in a typical running shoe and I had some sore muscles for a few days after just a 15 minute session.
Now, I guess the question is, is it worth it? Is the effort and time to make the switch to barefoot running worth it?
The Pose method site has some data about the forces produced in the
knee with conventional running shoes and styles compared to landing on
the forefoot and altering the stride. The force in the knee is less although the force in the lower leg is more. If you choose to run barefoot or close to it as in the Vibram's, make the switch very, very slowly. Your body, your foot and lower leg in particular, are not used to working that hard. But, if you give your self some time, you'll adapt.
I think there is some merit to the argument that by not using muscles and tendons an
d ligaments in the foot and lower leg that those tissues lose some capacity. The whole point of first going through rehab then reconditioning is to build up strength and capacity. Sometimes we have to use a more supportive shoe to assist the tissues. I've suggested shoes like the Z-Coil to people who have plantarfasciitis and they work great. But, the purpose of using a shoe like the Z-Coil is to get out of the shoe and into more conventional footwear. Likewise, there's an argument that the purpose of using a highly cushioned running shoe is to get out of the shoe too.
I like the way I feel running in the Vibram shoes (or gloves or whatever they're called) and will probably keep working at changing over to that style. But, my time line to do this is months and as my wife likes to say, "You're a very patient person."
And, I don't mind people staring at me.
