In Christopher McDougall’s Born to Run, a guy called Barefoot Ted swears by running with minimal foot protection and it kind of makes sense. Our feet evolved over millions of years to transport us everywhere, and we’ve have been running the entire time. Da Vinci called the foot “a masterpiece of engineering and a work of art”, and McDougall compares it to a complex, super-strong suspension bridge. It has 26 bones, 33 joints, 107 ligaments, 19 muscles and some tendons (thanks Google). Thousands of nerve endings make the feet mega-sensitive to stimuli (hence they’re ticklish).

Such acute responsiveness to pain taught our ancestors to run the way evolution intended, not the way running trainers enable us to. In contrast with the super-long-term evolution of the foot, the cushioned, supportive, “corrective” running shoe has been around less than a century. 80% of trainer-clad runners strike the ground heel first, whereas we naturally run with a forefoot strike – as illustrated by the Tarahumara running people of Mexico and other runners from non-Westernised cultures. Try it; the impact on the uncushioned heel makes it too painful on the foot and the shock shoots up the lower leg, jarring the knee.

McDougall is critical of the corporate giants pushing the latest state-of-the-art, mega-cushioned, super-corrective miracle running shoes on unwitting consumers (I’m guilty as charged). He points out that the best tried-and-tested models are often pulled from shelves to encourage runners to stockpile favourite shoes, and that there’s always some brand new “technology” to entice buyers with its promise of easier runs and faster times. Not to mention any names, Nike (again, guilty as charged), but the big names definitely have a vested interest in convincing us success comes from the purse.

McDougall describes how a top running coach at some American university experimented on his runners. He bought one group top-of-the-range, big bucks, high-tech running shoes and another group cheap, minimalist trainers. He found that the expensive shoes caused the runners to tire quicker and suffer more injuries than the cheapie ones. Similarly, another running  expert advocated the use of worn out, battered old shoes that  had lost much of their spring over brand new trainers. Hmmm.

Born to Run highlights the lack of injuries suffered by native runners with minimal or no footwear. It suggests that joint problems associated with repetitive pavement-pounding are more likely to be caused by the poor technique and unnatural gait which result from the over-compensation and over-protection of modern trainers. Constant support, particularly under the arch of the foot, weakens the soft tissue as it’s no longer needed to do its load-bearing job.

Running shoes enable us to run faster and further than our bare feet would, and prevent us feeling the pain that we evolved precisely to respond to. It’s easy to run too much in trainers, particularly when beginning a training programme as I recently have. The cushioning prevents our feet telling us when enough is enough, so our joints, muscles, tendons and ligaments end up absorbing way more shock than they’re accustomed to, resulting in injury.

I tried running barefoot on the treadmill and was amazed at the difference. My arches ached very quickly and my feet were much more sensitive to what was underneath them; I trod really lightly and much slower than usual. It’s the sort of thing you’d have to build up really slowly (remember that our ancestors started building up shoeless foot strength and tough soles since they learnt to walk) but I imagine it’s really liberating once you get there.

So perhaps trainers weaken our feet and make us run wrong. Perhaps they don’t. I just wanted to write about this because I found it really interesting. All in all, I won’t be ditching my Nike Pegasus Air Zooms just yet but I do plan to invest in some of the funny-looking five-toed running shoes that act as a second skin (once I find some money) to give barefoot running a go. I’m by no means an expert in anything foot, running or anatomy-related, but the barefoot theory seems logical to my keen little brain, and I could do with saving a small fortune on my next pair of shoes.
