Wiggling Their Toes at the Shoe Giants

TODD BYERS was among more than 20,000 people running the San Francisco Marathon last month. Dressed in shorts and a T-shirt, he might have blended in with the other runners, except for one glaring difference: he was barefoot.

Even in anything-goes San Francisco, his lack of footwear prompted curious stares. His photo was snapped, and he heard one runner grumble, “I just don’t want the guy without shoes to beat me.”

Mr. Byers, 46, a running coach and event manager from Long Beach, Calif., who clocked in at 4 hours 48 minutes, has run 75 marathons since 2004 in bare feet. “People are kind of weird about it,” he shrugs.

Maybe they shouldn’t be. Recent research suggests that for all their high-tech features, modern running shoes may not actually do much to improve a runner’s performance or prevent injuries. Some runners are convinced that they are better off with shoes that are little more than thin gloves for the feet — or with no shoes at all.

Plenty of medical experts disagree with this notion. The result has been a raging debate in running circles, pitting a quirky band of barefoot runners and researchers against the running-shoe and sports-medicine establishments.

It has also inspired some innovative footwear. Upstart companies like Vibram, Feelmax and Terra Plana are challenging the running-shoe status quo with thin-sole designs meant to combine the benefits of going barefoot with a layer of protection. This move toward minimalism could have a significant impact on not only running shoes but also on the broader $17 billion sports shoe market.

The shoe industry giants defend their products, saying they help athletes perform better and protect feet from stress and strain — not to mention the modern world’s concrete and broken glass.

But for all the technological advances promoted by the industry — the roll bars, the computer chips and the memory foam — experts say the injury rate among runners is virtually unchanged since the 1970s, when the modern running shoe was introduced. Some ailments, like those involving the knee and Achilles’ tendon, have increased.

“There’s not a lot of evidence that running shoes have made people better off,” said Daniel E. Lieberman, a professor of human evolutionary biology at Harvard, who has researched the role of running in human evolution.

Makers of athletic shoes have grown and prospered by selling a steady stream of new and improved models designed to cushion, coddle and correct the feet.

In October, for example, the Japanese athletic-shoe maker Asics will introduce the latest version of its Gel-Kinsei, a $180 marvel of engineering that boasts its “Impact Guidance System” and a heel unit with multiple shock absorbers. Already offered by Adidas is the Porsche Design Sport Bounce: running shoe, with metallic springs inspired by a car’s suspension system. It costs as much as $500.

Some question the benefit of all that technology. Dr. Craig Richards, a researcher at the School of Medicine and Public Health at the University of Newcastle in Australia — and, it should be noted, a designer of minimalist shoes — surveyed the published literature and could not find a single clinical study showing that cushioned or corrective running shoes prevented injury or improved performance. His findings were published last year in The British Journal of Sports Medicine.
Other experts say that there is little research showing that the minimalist approach is any better, and some say it can be flat-out dangerous.

“In 95 percent of the population or higher, running barefoot will land you in my office,” said Dr. Lewis G. Maharam, medical director for the New York Road Runners, the group that organizes the New York City Marathon. “A very small number of people are biomechanically perfect,” he said, so most need some sort of supportive or corrective footwear.

Nevertheless, a growing number of people now believe in running as nature intended — and if not barefoot, then as close to it as possible. They remain a tiny segment of the population — some would say fringe. But popular training methods like Chi Running and the Pose Method that promote a more “natural” gait, as well as “Born to Run,” a best-selling new book about long-distance running by Christopher McDougall, have helped spur interest.

Proponents of this approach contend that naked feet are perfectly capable of running long distances, and that encasing them in the fortress of modern footwear weakens foot muscles and ligaments and blocks vital sensory input about terrain.

“The shoe arguably got in the way of evolution,” said Galahad Clark, a seventh-generation shoemaker and chief executive of the shoemaker Terra Plana, based in London. “They’re like little foot coffins that stopped the foot from working the way it’s supposed to work.”

The big shoe companies are clearly paying attention to the trend. Nike was first to market with the Nike Free, a flexible shoe for “barefoot like running” with less padding than the company’s typical offerings. It was introduced in 2005 after Nike representatives discovered that a prominent track coach to whom they supplied shoes had his team train barefoot.

But some in the industry are critical of the barefoot push. Simon Bartold, an international research consultant for Asics, said advocates of barefoot running “are propagating a campaign of misinformation.”

SPEND some time in Concord, Mass., and you might catch a glimpse of a fit 51-year-old man in a pair of funny-looking socks running down the bucolic streets.
That would be Tony Post, the president and C.E.O. of Vibram USA, on a lunchtime run. And those socks? They’re actually thin rubber “shoes” with individual toe pockets. Called Vibram Five Fingers, they’ve been selling briskly to runners and athletes looking to strengthen their feet and sharpen their game.

When Vibram, an Italian company known for its rugged rubber soles, designed the Five Fingers a few years ago, company officials figured that they would appeal to boaters, kayakers and yogis. Instead, the shoes, which sell for $75 to $85, caught on with runners, fitness buffs and even professional athletes: David Diehl, the New York Giants tackle, trains in them.

Mr. Post, a shoe industry veteran, said he believed that the business was poised for a shakeup. “It used to be all about adding more,” he said. “Now, we’re trying to strip a lot of that away.”
Strange as they look, the Five Fingers shoes hark back to a simpler time. Humans have long run barefoot or in flat soles. Professor Lieberman’s research suggests that two million years ago, our ancestors’ ability to run long distances helped them outlast their prey, providing a steady diet of protein long before spears and arrows. More recently, at the 1960 Summer Olympics in Rome, Abebe Bikila, an Ethiopian runner, caused a stir when he ran the marathon barefoot and won.

Things changed in the early 1970s, when Bill Bowerman, a track coach turned entrepreneur, created a cushioned running shoe that allowed runners to take longer strides and land on their heels, rather than a more natural mid- or forefoot strike. Mr. Bowerman and his business partner, Phil Knight, marketed the new shoes under the Nike brand, and the rest is history.
At the same time, millions of Americans began taking up running as a pastime. Those twin trends ushered in a golden age of biomechanics research. “There was a lot of concern about injuries because of the boom,” said Trampas Ten Broek, manager of sports research at New Balance. The logic, he said, was that “if you build a heel lift and make it thicker, you take stress off the Achilles’ tendon.”

Walk into a sports store today and you’ll see the results: shoes with inch-thick heels and orthotics designed to correct overpronation, supination and a host of other ills.
Mr. McDougall, the “Born to Run” author,” said manufacturers, doctors and retailers were doing runners a disservice by pushing such shoes. “People are buying it thinking it’s going to do something for them, and it’s not,” he said.

Mr. McDougall’s book is centered on the Tarahumara Indians of Mexico, known for epic 100-mile runs with nothing on their feet but strips of rubber. The book has become something of a manifesto for barefoot runners.

After suffering chronic foot pain and being advised by sports medicine doctors to give up running, Mr. McDougall tried thin-soled shoes. Now, he said, he runs long distances without shoes — or pain.

THAT seems to be a common experience among barefoot converts. “When people get it, it’s almost biblical,” said Mr. Clark at Terra Plana. His initial line of minimal shoes, the Vivo Barefoot, is intended for walking; a performance model, the $150 Evo, is due at year-end.
Sales of minimalist shoes, while still tiny, are growing at a rapid clip. Mr. Clark figures that he will sell 70,000 pairs of minimal shoes this year, double last year’s volume. The shoes have sold mostly online and through 10 Terra Plana stores worldwide.

Vibram says sales of its Five Fingers have tripled every year since they were introduced in 2006, and Mr. Post said he expects revenue of $10 million this year in North America alone.
Many professionals agree that while barefoot running may have some benefits, those who are tempted to try running barefoot — or nearly so — should proceed slowly, as they should with any other significant change to their running habits. They also say that more research is needed.
Sean Murphy, engineering manager for advanced products at New Balance, says that there have been many studies suggesting “that shoes can correct biomechanical abnormalities and risk factors, therefore minimizing the likelihood of injury.”

When asked for an example, Mr. Murphy pointed to a 2006 study by three doctoral students that found that wearing the appropriate type of running shoe for one’s foot could reduce the shock of impact or unwanted rotation of leg bones. The study did not address injury rates.
AMID all the controversy, barefoot running and natural gaits are the subject of intensive research across the shoe industry. Companies don’t want to miss out if it turns out to be more than just a fad.

At New Balance’s sports research lab in Lawrence, Mass., Mr. Ten Broek and Mr. Murphy are studying the biomechanics of running barefoot and in soles of varying thickness, while designing a “lower profile” shoe.

Asics, too, sees promise in this area. “As technology improves, we will definitely go to a more minimal style,” Mr. Bartold said.

Those big companies could end up profiting from the movement — or they could have trouble getting on board.

Danny Dreyer, the founder of Chi Running, which uses the Tai Chi principles of harnessing energy and core muscles to promote a more effortless way of running, said he had worked with a few shoe companies to help design minimalist shoes. In each case, he said, marketing and profit concerns trumped design: “Their profit and direction is based on ‘More shoe is better,’ ” said Mr. Dreyer, who is also a long-distance runner.

Mr. Bartold of Asics, which has not worked with Mr. Dreyer, said the industry had runners’ best interests in mind. “It’s all about trying to protect the athlete,” he said.

Nike describes the Free, its minimalist shoe, as a “training tool.” It offers models with varying degrees of cushioning; they are priced at $55 to $110.

“The key is to offer a range of options, because every runner has different needs,” said Derek Kent, a Nike spokesman. “If you want that sensation of barefoot running, there is the Free, but if you want a product with a little more cushioning and support, we have that, too.”

While Nike would not disclose detailed sales information, Mr. Kent said sales of the Free grew at double-digit rates in the last two fiscal years, with sales in Japan and China especially strong.
Curt Munson, co-owner of Playmakers, a running shop in Okemos, Mich., said that in his conversations with major shoe companies lately, “they see that they need to address this” but “they’re just not sure how much.” But, he said, they must be thinking, “If we say this is the best, then are we saying that what we’ve done before is not good?”

The back-to-basics movement is more than a fad, said Mr. Munson, who runs in Five Fingers. “Most people are not ready to run barefoot,” he said, “but I do think they are ready to go back to ‘less is more.’ ”

Chia Nature's wonder food

Article provided by Living Foods.com
http://www.living-foods.com/articles/chia.html

Chia, is familiar to most of us as a seed used for the novelty of the Chia Pet™, clay animals with sprouted Chia seeds covering their bodies. Little is known, however, of the seeds tremendous nutritional value and medicinal properties. For centuries this tiny little seed was used as a staple food by the Indians of the south west and Mexico. Known as the running food, its use as a high energy endurance food has been recorded as far back as the ancient Aztecs. It was said the Aztec warriors subsisted on the Chia seed during the conquests. The Indians of the south west would eat as little as a teaspoon full when going on a 24hr. forced march. Indians running form the Colorado River to the California coast to trade turquoise for seashells would only bring the Chia seed for their nourishment.

If you try mixing a spoonful of Chia in a glass of water and leaving it for approximately 30 minutes or so, when you return the glass will appear to contain not seeds or water, but an almost solid gelatin. This gel-forming reaction is due to the soluble fiber in the Chia. Research believe this same gel-forming phenomenon takes place in the stomach when food containing these gummy fibers, known as mucilages, are eaten. The gel that is formed in the stomach creates a physical barrier between carbohydrates and the digestive enzymes that break them down, thus slowing the conversion of carbohydrates into sugar.

In addition to the obvious benefits for diabetics, this slowing in the conversion of carbohydrates into sugar offers the ability for creating endurance. Carbohydrates are the fuel for energy in our bodies. Prolonging their conversion into sugar stabilizes metabolic changes, diminishing the surges of highs and lows creating a longer duration in their fueling effects.

One of the exceptional qualities of the Chia seed is its hydrophilic properties, having the ability to absorb more than 12 times its weigh in water. Its ability to hold on to water offers the ability to prolong hydration. Fluids and electrolytes provide the environment that supports the life of all the body’s cells. Their concentration and composition are regulated to remain as constant as possible. With Chia seeds, you retain moisture, regulate, more efficiently, the bodies absorption of nutrients and body fluids. Because there is a greater efficiency in the utilization of body fluids, the electrolyte balance is maintained.

Example: Fluid and electrolyte imbalances occur when large amounts of fluids are lost resulting from vomiting, diarrhea, high fever, or more commonly from sweating? The loss of extracellular fluid occurs in these conditions. Intercellular fluid then shifts out of cells to compensate, causing abnormal distribution of electrolytes across cell membranes resulting in cellular malfunction. So. Retaining and efficiently utilizing body fluids maintains the integrity of extracellular fluids, protecting intercellular fluid balance. The results of which ensure normal electrolyte dispersion across cell membranes (electrolyte balance), maintaining fluid balances, resulting in normal cellular function.

Chia seeds are the definitive hydrophilic colloid for the 21 century diet. Hydrophilic colloids, (a watery, gelatinous, glue-like substance) form the underlying elements of all living cells. They posses the property of readily taking up and giving off the substances essential to cell life. The precipitation of the hydrophilic colloids cause cell death.

The food we eat, in the raw state, consist largely of hydrophilic colloids. When cooked on the other had, precipitates its colloidal integrity. This change in the colloidal state alters the hydration capacity of our foods so as to interfere with their ability to absorb digestive juices. If we were to eat a raw diet we wouldn’t need to introduce the addition of any hydrophilic colloid to our diet. Uncooked foods contain sufficient hydrophilic colloid to keep gastric mucosa in the proper condition. But even with raw foods, they must first be partially broken down by the digestive juices, beginning in the mouth and continuing through he upper tract, to allow the gelatinous reaction to take place. Because of this upper tract digestive process, those who suffer from slow digestion, gas formation, relaxed cardia and heartburn in which the burning is due to organic acids instead of an excess of the normal hydrochloric acid, which frequently accompanies chronic inflammation disease affecting such organs as the heart, lungs, gall bladder and appendix, are usually restricted from eating raw foods. A hydrophilic colloid incorporated with these foods may be used either in connection with the patients regular food or with whatever diet the physician feels is best suited for his patient. The patient with gastric atony or nervous indigestion who complains of heartburn and/or vomiting four to five hours after eating is often helped. There is a lessening of emptying time if the stomach and an improvement in gastric tone. A strict dietary regimen is at as necessary when the hydrophilic.

Chia seed may be used in conjunction with almost any diet your doctor or nutritionist feels is necessary for your condition. The Chia’s hydrophilic colloidal properties aid the digestion of any foods contributing to the patients suffering as a result of a sour stomach. Even if you have sensitivity to certain foods, they may be tolerated with slight discomfort or none at all if a hydrophilic colloid is made a part of your diet. The positive effects on the digestion in the upper portion of the gastrointestinal tract often leads to puree their foods may find benefits from hydrophilic colloids which may lead to eliminating the necessity for pureeing. Even raw vegetables, green salads and fruits, which are largely restricted, may often be given to these patients with little or no discomfort after a short time.

There are several hydrophilic foods available that offer these natural benefits. Cactus juice, beet juice, agar, the edible seaweeds, and many proprietary preparations, which include the silica gels, mucilaginous substance of vegetables origin, are among colloids that prove effective. Each one of the above mentioned substances have one or more drawbacks. They are either too expensive, they may produce toxic side effects, bad tasting, not readily available, insufficient hydration capability, or it is indigestible.

Chia seed, a muscle and tissue builder and an energizer of endurance with extensive hydration properties, possesses none of the above disadvantage, and because if its physiochemical properties, supports effective treatment in immediate problems of digestion. Exactly why this should be true may be puzzling at first. However, if we consider the effect of unusual irritation upon the nerves of the gastrointestinal canal, it is reasonable the think that a less violent and more balanced digestion might quiet the activity of the otherwise hyperactive gut. Inasmuch as the same foods, which formerly produced irritation, may frequently be continued without harm when hydrophilic colloids are used. The relief to nerve irritation seems to offer a logical explanation.

The change, in the lower gastrointestinal tract, is due to the effect of the hydrophilic colloid and to a more complete digestion-taking place along the entire tract due to physiochemical alterations. Both factors are important, as there is undoubtedly a better assimilation of food that supports enhanced nutritional absorption while significantly extending necessary hydration as well as encouraging proper elimination.

As a source of protein, the Chia, after ingestion, is digested and absorbed very easily. This results in rapid transport to the tissue and utilization by the cells. This efficient assimilation makes the Chia very effective when rapid development of tissue takes place, primarily during growth periods if children and adolescents. Also for the growth and regeneration of tissue during pregnancy and lactation, and this would also include regeneration of muscle tissue for conditioning, athletes, weight lifters, etc.

Another unique quality is the Chia seed is its high oil content, and the richest vegetables source for the essential omega-3 fatty acid. It has approximately three to ten times the oil concentrations of most grains and one and a half to two times the protein concentrations of other grains. These oils, unsaturated fatty acids, are the essential oils your body needs to help emulsify and absorb the fat soluble vitamins, A, D, E, & K. Chia seeds are rich in the unsaturated fatty acid, linoleic, which the body cannot manufacture. When there are rich amounts of linoleic acid sufficiently supplied to the body trough diet, linoleic and arachidonic acids can be synthesized from linoleic acid.

Unsaturated fatty acids are important for respiration of vital organs and make it easier for oxygen to be transported by the blood stream to all cells, tissues, and organs. They also help maintain resilience and lubrication of all cells and combine with protein and cholesterol to form living membranes that hold the body cells together.

Unsaturated fatty acids are essential for normal glandular activity, especially of the adrenal glands and the thyroid glad. They nourish the skin cells and are essential for healthy mucus membranes and nerves. The unsaturated fatty acids function in the body by cooperating with vitamin D in making calcium available to the tissues, assisting in the assimilation of phosphorus, and stimulating the conversion of carotene into vitamin A. Fatty acids are related to normal functioning of the reproductive system. Chia sees contain beneficial long-chain triglycerides (LCT) in the right proportion to reduce cholesterol on arterial walls.

The Chia seed is also a rich source of calcium as it contains the important mineral boron, which acts as catalyst for the absorption and utilization of the calcium by the body.
Chia, as an ingredient, is a dieters dream food. There are limitless ways to incorporate the Chia seed into your diet. Chia must be prepared with pure water before using recipes. The seed will absorb 9 times it’s weight in water in less than 10 minutes and is very simple to prepare.

Food Extender/Calorie Displacer: The optimum ratio of water to seed, for most recipes, is 9 part water to 1 part seed. One pound of seed will make 10 pounds of Chia gel. This is the most unique structural quality of the Chia seed. The seed’s hydrophilic (water absorbing) saturated cells hold the water, so when it is mixed with foods, it displaces calories and fat without diluting flavor. In fact, I have found that because Chia gel displaces rather than dilutes, it creates more surface area and can actually enhance the flavor rather than dilute it. Chia gel also works as a fat replacer for many recipes.

Making Chia Gel (9to1 ratio): Put water in a sealable plastic container and slowly pour seed into water while briskly mixing with a wire whisk. This process will avoid any clumping of the seed. Wait a couple of minutes, whisk again and let stand for 5 to 10 minutes. Whisk again before using or storing in refrigerator (Gel will keep up to 2 weeks). You can add this mix to jams, jellies, hot or cold cereals, yogurts, mustard, catsup, tarter sauce, BBQ sauce, etc.. Add the gel, between 50% to 75% by volume, to any of the non-bake mentioned foods, mix well and taste. You will notice a very smooth texture with the integrity of the flavour intact. In addition to adding up to 50% to 75% more volume to the foods used, you have displaced calories and fat by incorporating an ingredient that is 90% water. Use as a fat replacer, for energy and endurance, or for added great taste, buy substituting the oil in your breads with Chia gel. Top your favorite bread dough before baking with Chia gel (for toping on baked goods, breads, cookies, piecrust, etc., reduce the water ration to 8 parts water to 1 part Chia seed) for added shelf life.

There are additional benefits from the Chia seed aside from the nutritive enhancements when used as an ingredient. It was also used by the Indians and missionaries as a poultice for gunshot wounds and other serious injuries. They would pack the wounds with Chia seeds to avoid infections and promote haling. If you place a seed or two in your eyes it will clean your eyes and will also help to clear up any infections. There is a wealth of benefits beyond the information outlined in this article and treasure-trove of benefits yet to be discovered. Chia seed, having a qualitatively unique situational richness along with a profound nutritive profile is one of man’s most useful and beneficial foods and is destined to be the Ancient Food of the Future.

Born to Run by Christopher McDougall

This is the best book I have ever read! It is very inspirational and motivating. There is so much good information in it about running, form, diet, etc...

I HIGHLY recommend this book to anyone that wants to get into running and have it feel good! I cannot put this book down when I pick it up. It is very well written, and so enjoyable to read.

Follow the link on the right of the page to pick one up from Amazon, and start on your journey to a better, healthier you! Learn the secrets of the Tarahumara tribe of Mexico, some of the greatest runners of all time!

He wrote the book based on one question he had: Why does my foot hurt?
He talks about how our feet are designed to be used and to run, and how modern shoes and all the fancy technologies we have have caused our injuries.

He makes a very strong case for barefoot running in this book. So I am setting out to see how it will work for me.
