While exploring this curious (primitive!) idea of going barefoot, and walking barefoot, I remembered about Milkha Singh and spent 15 minutes researching the idea of barefoot running (Note that I have no plans to run barefoot!).
Milkha Singh was very big in our times in India. I was fortunate to see him in my school in Hyderabad (Kendriya Vidyalaya Picket) in the 1970s. Milkha Singh ran the 400 metre race at the MCG in Melbourne in the 1956 Olympics barefoot(he was eliminated in the heats). He later took to wearing shoes, I gather, but most of his skill was acquired running barefoot in army cantonments where he started life as a jawan.
The natural cure of my dry eyes and eye strain problem is holding up very well (not yet 100% cured but pretty much manageable. I was even able to watch a complete movie yesterday [Fiddler on the Roof – outstanding movie], something that has been virtually impossible for me to do for the past eight months due to the intense pain experienced in front of any screen, including the TV). If eye specialists were to use my cure, they'd genuinely benefit their patients. And the world could save BILLIONS of dollars.
But now for another interesting piece of information.
My gym instructor mentioned yesterday that there are many health benefits of barefoot contact with the ground. This is a preliminary post on this subject – to record a few key benefits, based on my instructor's comments, as well as a short internet search. I've not yet started using this general therapy but will provide further comment after trying it out.
A study entitled, "Shod Versus Unshod: The Emergence of Forefoot Pathology in Modern Humans?" in the podiatry journal The Foot, noted 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."
The poor bio-feedback through shoes can cause poor posture and other problems:
It takes only milliseconds for sensory information from your foot to reach your brain and for your brain to respond by making adjustments to muscles in your legs, back and arms. By contrast, walking in shoes is far more clumsy and inefficient due (in part) to impaired biofeedback. Muscle contractions, impact forces and joint range-of-motion are measurably different when barefoot [Source]
Impact on body of walking barefoot even on steel is virtually zero
My friend Daniel Lieberman at Harvard (the other barefoot professor) has demonstrated in his research that impact forces on the body are virtually zero when running barefoot, even on the hardest man-made surfaces like steel. Thus, the body’s shock-absorption mechanisms are perfectly capable of handling the hardest of terrains. By the way, impact forces are not zero when running on hard surfaces in shoes. [Source]
Ninety per cent of our foot (and many of our spinal) problems are caused by shoes
There is an excellent video interview with Associate Prof. Howell on the top right hand side, here. This professor does not use shoes for most of his daily activities. In addition, here's a youtube clip of his book.
