Joy in Walking

The shining red sun is my heart.
Each flower smiles with me.
How green, how fresh all that grows.
How cool the wind blows.
Peace is every step.
It turns the endless path to joy.
- Thich Nhat Hanh

As a follow up to my last post, I thought I would look at feet and stepping from a different viewpoint. The last blog post looked at our feet in terms of shoes and orthopedic health. In addition to numbing our proprioceptive abilities, shoe overuse makes us liable to just mindlessly ignore our feet. Not only do we forget how to walk properly, but we also lose the ability to just pay attention to our feet.

A core tenet of Zen is the idea of being present. It’s a very simple principle: just bring your mental focus and awareness into the here and now. As simple as that sounds, it’s not something that a lot of people can actually do, particularly given the hustle and bustle of modern life. The mind will naturally wander, dwelling on the past, conjecturing about the future, and latching on to the host of random thoughts that arise. Learning to not let those thoughts control your attention is an important step in truly bringing yourself into the moment and developing mindfulness.

A common method of developing mental focus (meditation) and bringing your attention to the present is to pay attention to one’s breathing. Another is to pay attention to the process of walking. Walking, much like breathing, may seem like a very simple act, but if you really pay attention, the superficially simple process becomes complex and multifaceted. The body’s weight falls to the heels and rolls towards the balls of the feet and toes. The arch of the foot helps flexibly transfer force from heel to toe. The toes grip the ground, and the muscles of the feet help stabilize the foot and adjust to transfer force efficiently. The ankles flex to mobilize the foot and keep the body stable relative the foot. The simple act of bipedal walking is complex enough to require lots of robotics engineering research to replicate, but most people take it for granted.

Just paying attention to the feet while standing and stepping is very perceptually rich. Like paying attention to breathing, standing and walking meditations also provide methods of mental focus to bring the mind into the present. Noticing the feet (and eventually other parts of the body) shifts the mental focus away from random distracting thoughts and brings attention to a moment by moment process. Even the simple act of learning to perceive your feet helps develop mindfulness. Paying attention to your feet can be a first step towards mindfulness, mental clarity, and maybe even a bit of inner peace.

Feet: Well Grounded and Down to Earth

Statue of footIsn’t it odd how we pay so little attention to such an important part of our foundation? I am of course talking about our feet. They support us everyday and are the part of us most directly connected to the earth, yet we usually give them little heed.

Our feet were meant to be free and mobile, gripping and sensing the ground beneath us. However, this is not how our feet actually experience the world. For a myriad of reasons, we largely clad our feet in shoes. While there are certainly good reasons to wear shoes, constantly ensconcing our feet in a protective enclosure constricts and weakens our feet, dulls their proprioception, and reduces our perception of the wealth of tactile information from our soles. According to recent news, including this New York Magazine article, shoes are wrecking our feet. Shoes are designed to stabilize, protect, and make fashion statements. In other words, shoes primarily serve to immobilize our feet so we walk unnaturally, cushion them until they’re senseless, and give us consumerist driven social standing (while padding the pockets of the shoe designers).

Our bare feet are actually quite well adapted to keeping us standing upright. The body weight is supported via the heel, two balls, and outside edge of the foot. The toes grip the ground while the toes and ankle work in tandem to stabilize the upright balance. While walking, our unshod feet will naturally land lightly on the heel, and flexibly transfer energy towards towards the outer edge of the foot, the arch, and finally to the balls of the feet and toes to push off for the next step. For the most part shoes don’t allow our feet to function this way.

Ironically, supportive and well cushioned shoes can result in the opposite of their original intent. They can actually weaken your feet and ankles so that you’re more prone to injury, and they also promote bad biomechanics which transmit more shock to your joints. Let’s do a cursory examination of where shoes go wrong (we’ll ignore the egregious example of high heels and other “fashionable” shoes for now, since everyone should know that those are terrible for you). Your typical athletic shoe has a relatively thick, stiff sole, ample cushioning, arch support, a slight downward slope (elevated heel), and an upward curl towards the toes. The cushioning acts as a shock absorber and significantly reduces impact, but the combination of the thick sole and cushioning means you get no tactile information about the ground from your feet. Consequently, you can quite literally slam your heels into the ground and walk with a lot higher stepping impact than you would without a shoe. If not for the cushioning, stepping would normally land more lightly on the heel.

Lots of shoe cushioning results in a elevated, destabilized foot, a winning combination for sprains for someone with insufficiently strong ankles. To compensate for this destabilization, rigid soles, ankle support, and sometimes wider soles are used to add stability. But with a rigid sole, the foot can no longer flexibly mobilize to transfer force from the the heel to toes to push off for the next step. The solution? Make the shoes slope downward and taper the front of the shoe upward so that your step will now simulate a roll from heel to toe and help you push off the front of the foot. If you’ve got fancier shoes, there may even be grooves cut into the sole to give some flexibility to the front of the shoe and better simulate pushing off from the ball of the foot and toes.

With all this artificial support, we come to rely on the shoe to do most of the stepping work for us. Our feet and ankles are stabilized, the slope and front taper perform the push off work, and even the arch support makes it unnecessary to use any of our foot muscles to actually support our feet. With the upward front shoe taper, our toes no longer grip the ground but instead curl non-functionally upward. This weakens the toes, making them less able to assist in pushing off while stepping and less able to function in general balance and stabilization. All in all, inattentive and constant use of shoes can result in weakness and lack of mobility in the feet and ankles.

Weakness and lack of mobility in the feet and ankles lead to hosts of problems. The most obvious consequence would be issues with the feet and ankles. In addition, if the feet and ankles don’t function properly, the body usually needs to compensate for the insufficiency at the feet by overusing another part of the body, such as the knees, hips, and back. Discussing the amazingly interconnected biomechanics of the human body is far beyond the scope of this blog post. But suffice it to say that the body works best as a unified whole. When one part breaks or doesn’t work right, other parts will usually try to pick up the slack. This can easily stress the body since it’s forced to function in a way for which it wasn’t designed. The strained biomechanics from incorrectly functioning feet can cause injuries to distant parts of the body in ways which aren’t immediately obvious.

Countries which don’t have such prevalent shoe use suffer from fewer foot health issues than countries where shoe use is more widespread. Spending more time walking around barefoot and learning to use our feet properly would do wonders for improving our biomechanics and overall orthopedic health. Running or doing more sports training barefoot appears to improve athletic performance, though these more physically demanding activities require some preliminary strength and conditioning before serious barefoot training can begin in earnest.

Vibram FivefingersOf course, that doesn’t mean giving up shoes entirely is completely practical. Regular shoes probably aren’t going to disappear anytime soon. Social, professional, and sometimes even just safety and hygienic issues are going to force us to wear shoes at least sometimes. There are a few (though not many) commercially available “barefoot shoe” alternatives. Vivo Barefoot shoes provide a nice-looking, if somewhat pricey, shoe that close mimics barefeoot walking. Vibram FiveFingers are about as close to barefoot as you get in a shoe, though you’ll certainly attract a lot of attention with their unique design. Water shoes (a.k.a. aqua shoes, aqua socks, surf shoes, bathing shoes, etc) can also provide a a flexible, thin soled, readily available, and relatively cheap alternative. Nike has is Nike Free line of shoes for those wanting something closer to a conventional running shoe. If you want to go the outdoorsy, back to nature route, you can try some mocassins, but those likely won’t last long on the vast trails of urban pavement.  EDIT (6/6/08): I found one more possibility with trampoline or gymnastics shoes.  They also may not last long on pavement though.

Regardless of whether we choose to live barefoot lifestyle or shelter our feet inside shoes, it is certainly beneficial to mind our feet. Caring for our feet and ensuring that they have adequate strength and mobility goes a long way to keeping us healthy and fit.

The Best Season

Four Seasons

Spring comes with its many blossoms, Autumn with the moon,
Summer brings refreshing breezes, Winter the snow;
When useless concerns don’t burden the mind,
That is your best season.

* Zen poem by 無門慧開 Wu-men Hui-kai

That was a poem shared with me which I think expresses a very Zen concept: being present and living in the moment. The translation is based loosely on that from The Light Inside the Dark and my own interpretation of the characters.

Modern life undoubtedly has brought us many great things: medical advances, high standards of living, relatively high levels of wealth, technological wonders, etc. But with that modern progress has also come an increasing drive to cram more and more into our already busy lives. Businesses constantly strive to increase productivity and output. Hordes of marketing messages bombard us, vying for our attentions through every possible media outlet. Technology has brought about innumerable means to distract ourselves and keep us constantly preoccupied. And this is even before we include the personal attentions needed for interactions with family and friends. There’s an overwhelming bounty of issues occupying our attentions and filling our minds.

All this busy-ness and preoccupation doesn’t foster personal growth or fulfillment. It’s too easy to become so overly wrapped up in all of our worries that we lose ourselves as life zooms along. If we’re not mindful, we forget how to relax and not let everything constantly wear us down. It’s good to remind ourselves that we should regularly stop and just be. The mind can easily become fettered by worries of the future, dwellings in the past, and hosts of other meaningless thoughts. You can really only experience life in the present. Letting go of all the cluttering thoughts frees the mind so that we can appreciate life in the here and now.

welcome mat

Welcome, reader. Zenfulness is now live and launched, and so starts the beginning of my latest blogging adventure.

The first question I imagine most people having would be “what exactly is Zenfulness?” That’s a good question, and one for which I don’t have a definitive answer. The name itself is a wordplay combining Zen and mindfulness. Though Zen (or Ch’an, 禪) has special significance in my life, I don’t claim to be any great expert in it. I find the guiding principles of Zen (mindfulness, experience of the present moment, and non-attachment) provide a useful framework for approaching many subjects.

Zen concepts are particularly apt for exploring the mind. Since Zen (and Buddhism in general) are often associated with studies and training of the mind, this is not surprising. But our minds are inextricably linked to our physical bodies and the experiences of our daily lives. Given that fact, I’ll begin this blog by focusing posts on understanding and developing the mind, maintaining a fit and healthy body, and bringing a touch of Zen perspective. That focus should provide a good launching point for establishing a working definition of Zenfulness. Hopefully, some of my posts will spur your thoughts and inspire you to come up with your own Zenfulness defintion.
