Modern natural

Date April 25, 2008

I’m certainly not anti-technology. I am after all a web developer. But I think there are a lot of things that we’ve done to ourselves to correct perceived deficiencies in how our bodies operate, creating new problems in the process. I’ve written before about my attempt to regain a natural sleep pattern. Walking is apparently the next on my list.

Thanks to Cory Doctorow, I read this article on the damage we do to ourselves with shoes. Not just fancy shoes, but even sport shoes. And then I read this review and this review of the Vibram fivefinger shoe and that was pretty much all she wrote.

The theory behind the shoe is that you don’t need to cushion your feet nearly as much as people do. In fact, the cushioning and over-protecting of our feet might be what leads to other kinds of joint pain. So what we ought to do is make shoes that work with our feet, the way they were designed, rather than fight to correct apparent design defects.

It’s a way of thinking about technology that I find rather compelling: let’s start with the idea that the way our body works is effective, then try to find ways to augment that performance. These (and similar) shoes do that by allowing your foot to operate as it was designed but giving the foot considerably better protection from the elements.

I’ve yet to try them of course; I ordered them just this morning. But after I get them and try them I’ll come back and let you know what I think.

    “let’s start with the idea that the way our body works is effective…”

    But that may be incorrect assumption to start with. My podiatrist has told me (and one of his peers told a friend of mine) that the human body is not designed efficiently. Our feet and legs have not fully caught up with our becoming bipedal. I don’t know enough about biology to give specifics, but these doctors told us that some common foot ailments such as bunions and neuromas are the result of “design flaws.” Not flaws in our shoes, but flaws in the way feet are constructed.

    Similarly, woman often have knee and ankle problems because our joints cannot accomodate our widened pelvises. The angle of the leg doesn’t work correctly to support us.

    It certainly doesn’t work correctly to support us with the shoes that we currently wear; I’m inclined to think it’s possible that we’ve been trying to correct problems caused by our shoes rather than problems caused by our bodies. Recent research seems to bear this out.

    I was looking at those shoes yesterday, myself. Let me know what you think of them.

    Just a follow up to what Missie wrote; I do remember in my physical anthropology courses being taught that our bipedalism is what causes such difficulty and pain in childbirth (compared with other mammals), and also leads to back problems and such.

    That’s been the common wisdom and operative theory for a very long time, but recent studies are starting to challenge that notion, or at least suggest that our current solutions — which seek to override and supplant the natural operation of our feet — exacerbate the problem.

    From You Walk Wrong:

    Last year, researchers at the University of the Witwatersrand in Johannesburg, South Africa, published a study titled “Shod Versus Unshod: The Emergence of Forefoot Pathology in Modern Humans?” in the podiatry journal The Foot. The study examined 180 modern humans from three different population groups (Sotho, Zulu, and European), comparing their feet to one another’s, as well as to the feet of 2,000-year-old skeletons. The researchers concluded that, prior to the invention of shoes, people had healthier feet. Among the modern subjects, the Zulu population, which often goes barefoot, had the healthiest feet while the Europeans—i.e., the habitual shoe-wearers—had the unhealthiest. One of the lead researchers, Dr. Bernhard Zipfel, when commenting on his findings, lamented that the American Podiatric Medical Association does not “actively encourage outdoor barefoot walking for healthy individuals. This flies in the face of the increasing scientific evidence, including our study, that most of the commercially available footwear is not good for the feet.”

    and

    “Natural gait is biomechanically impossible for any shoe-wearing person,” wrote Dr. William A. Rossi in a 1999 article in Podiatry Management. “It took 4 million years to develop our unique human foot and our consequent distinctive form of gait, a remarkable feat of bioengineering. Yet, in only a few thousand years, and with one carelessly designed instrument, our shoes, we have warped the pure anatomical form of human gait, obstructing its engineering efficiency, afflicting it with strains and stresses and denying it its natural grace of form and ease of movement head to foot.” In other words: Feet good. Shoes bad.

    In 2006, a group of rheumatologists at Chicago’s Rush Medical College studied the force of the “knee adduction moment”—basically, the force of torque on the medial chamber of the knee joint where arthritis occurs. For years, rheumatologists have advised patients with osteoarthritis of the knees to wear padded walking shoes, to reduce stress on their joints. As for the knee-adduction moment, they’ve attempted to address it with braces and orthotics that immobilize the knee, but with inconsistent results. So the researchers at Rush tried something different: They had people walk in their walking shoes, then barefoot, and each time measured the stress on their knees. They found, to their surprise, that the impact on the knees was 12 percent less when people walked barefoot than it was when people wore the padded shoes.

    I don’t have a degree in anthropology, but I had several courses in college and I agree with the comments by MTB and Chrissy. Those are the operative theories and have come from many, many years of research.

    An article from NY Magazine that talks to two random studies does not mean those theories are incorrect, nor does it mean they are being (properly) challenged. We don’t know if any proper scientific method was used in those studies, nor do we know if the research was peer-reviewed. Many scientists publish their studies that challenge common notion, but it doesn’t mean we jump head-first into every new theory out there.

    Good luck with the shoes…although, and no offense, they look pretty ridiculous.

    BB, you’re right — two studies don’t necessarily denote a scientific consensus, and the shoes do look ridiculous. But I’m not going to let that stop me. I look pretty ridiculous to begin with.
