Natural Running as Positive Deviance?

Posted by on Thursday, February 3, 2011 @ 11:28 am | 1 Reply

Over 150 people turned out (and another 50 or so were turned away due to lack of space) for last week’s speaker panel  discussion about natural running in Sheperdstown, West Virginia.

Event attendee and blogger Pete Larson (www.runblogger.com) was struck by the turnout in a small town in West Virginia, which has a reputation as one of America’s most obese states. “I couldn’t believe it!” Larson wrote on his blog. “Here we were in a state renowned for it’s inactivity, and I had to weave my way through a crowd of people who were squeezing into a room like sardines.”

Dr. Mark Cucuzella, organizer of the event, titled The Re-Evolution of Running: Discover Pain Free Movement for Life, attributes to tremendous response to a phenomenon called positive deviance. “That’s when large change happens as a result of observing and following what is happening in a small sector, and then applying it widely,” he says.

Cucuzella is also a family doctor and owner of Two Rivers Treads Center for Natural Running and Walking store in Sheperdstown, West Virginia.

Blogger Miss Zippy shares in this recent post what she learned from the panel of experts that included Danny Dreyer, founder of ChiRunning, Jerry Lee, CEO of Newton Running, Dr. Jay Dicharry, PT and Director of the SPEED Clinic at the University of Virginia, Dr. Peter Larson, Blaise Dubois, running injury authority, among others.

Beware of Barefoot Running Injuries

Posted by on Tuesday, June 15, 2010 @ 9:17 am | 19 Replies

by Danny Abshire, co-founder, Newton Running

People have been experimenting with barefoot running for a long time, but in recent years the activity has gained mainstream notoriety and science-based credibility.

Most coaches, elite athletes, physiologists and other medical experts agree that running barefoot in very small doses on soft surfaces can help improve your running mechanics and teach your body to land lightly at your midfoot, but they also agree that you should wear some kind of running shoes most of the time.

“Throw your shoes away for good? Sure, if you have perfect mechanics and you’ve been living barefoot all of your life,” says Dr. Mark Cucuzzella, a West Virginia University professor and 2:25 marathoner who has studied barefoot and minimalist runners in relation to running injuries. “But that’s not the majority of runners. Most runners absolutely need to wear shoes when they run.”

What Shoe Type is Best?

If you’re used to running in a traditional training shoe with a built-up heel, running barefoot can be a fascinating experience of freedom and can be the first step in developing natural running mechanics. Running unshod your foot naturally seeks out the ground by landing at the midfoot/forefoot, where it receives sensory interaction, or afferent feedback.

This sensory input immediately tells the rest of the body how to move efficiently with light footsteps, a high leg cadence, a relaxed but consistent arm swing, an upright posture and a slight forward lean from the ankles. This same feedback can be gained while wearing some types of lightweight shoes, but traditional trainers with thick levels of foam dampen the sensory interaction and make it much harder to interpret the ground, especially with the heel-striking gait those shoes promote.

How Run “Barefoot” in Shoes

Landing lightly at your midfoot and picking up your foot quickly to start a new stride is the most effective way your body knows to propel and protect itself while running. Conversely, your body generally doesn’t allow you to land on your heel if you’re running barefoot (especially on a hard surface) because it isn’t engineered to accommodate the blunt force trauma of repeated heel striking.

True, the calcaneus (heel) bone is a large bone, but it was designed to take the lower impacts of a walking gait and help balance the body as it rolls forward, as well as to help support and balance the body in a standing position as the rear point of a tripod.

Accepting large impacts on the heel bone from heel-strike running on the roads barefoot sends tremendous shockwaves (or impact transients) up your body. Those impact transients can have numerous negative affects upstream as your body tries to offset that force and remain balanced, including various forms of tendinitis, illiotibial band strains and adverse sheering in the pelvis and lower spine.

“It’s no different than somebody hitting you on the heel with a sledgehammer with 300 to 400 pounds of force,” says Dr. Daniel Lieberman, the Harvard University evolutionary biologist who concluded in a study released in January 2010 that running with midfoot footstrikes, either barefoot or in shoes, is better and less impactful than heel-striking. “So if you’re going to do that, it makes sense to wear shoes. A shoe makes that comfortable. A shoe essentially slows that rate of loading enormously — by about sevenfold in a typical shoe — and that’s what makes it comfortable and that’s why a lot of people can wear shoes and heel-strike.”

Newton Running’s Take on Barefoot Running

Posted by on Friday, January 29, 2010 @ 2:13 pm | 3 Replies

In the past few days we’ve been inundated with calls and messages from friends, customers and fans asking, “Did you see NPR.org barefoot running story or
BBC barefoot running story story about barefoot running?”

The answer is yes, we’ve seen Dr. Lieberman’s studies at Harvard and it clearly validates what Newton Running is all about.

Please read the open letter below from Newton Running co-founder Danny Abshire and our Director of Education, Ian Adamson.

Our Take on Barefoot Running

Many of you have seen or heard the numerous national news stories about barefoot running in the past few days. This news comes on the heels of the recently published study, Foot strike patterns and collision forces in habitually barefoot versus shod runners by Harvard University anthropologist Dan Lieberman.

Dr. Lieberman and colleagues concluded that modern, cushioned running shoes change the way humans run and hypothesize based on their biomechanical findings that forefoot and some midfoot strikes may make runners less prone to some kinds of injury. (He explains his hypothesis in this video).

That comes as no surprise to us at Newton Running. Our company was founded on the belief that the lifted heel in modern running shoes promotes improper form and can contribute to various injuries. Our shoes are designed specifically to accommodate and enhance natural running foot-strike and gait and are based on decades of research and observation on shoe technology and running mechanics.

Running barefoot is not a viable option for most people, except for short training sessions on forgiving surfaces. Plus, the transition to barefoot running or ultra-minimalist shoes can be difficult and/or painful for runners who have spent their whole lives running in heavily cushioned and overly structured shoes.

Newton Running shoes feature a geometry and design that facilitates your natural gait and protects you from harsh running surfaces. We offer the only viable alternative to both modern running shoes and barefoot/ultra-minimalist shoe running.

Newton Running Shoe Design

1. Typical running shoes feature a thick, padded heel and a steep heel-to-forefoot ramp angle (gradient), which encourages heavy heel striking, increases shock loads and dampens afferent feedback (the ability to sense the surface under your shoes). Newton Running shoes have a negligible gradient (between 1% and 3%), which allows your foot to land with a reduced impact and take advantage of your body’s natural suspension system. (click images to enlarge)

2. Newton Running shoes provide industry-leading impact force reduction and energy return with our proprietary Action/Reaction Technology™ strategically placed on the sweet spot under your forefoot.

sweetspot

3. Newton Running shoes are built with a biomechanical plate positioned directly under your metatarsals to enhance afferent feedback and allow your feet to spread naturally under load. The soft foam in regular running shoes dampens and blocks valuable protective feedback at foot strike. Without feeling the ground, runners will impact and push harder, creating the possibility for injury.

4. The anatomically designed upper and midsole allows your foot to move naturally throughout the gait cycle. In contrast, most modern running shoes are highly structured, rigidly encasing your foot and preventing natural movement. Over time, this weakens the foot and creates overuse of propulsive muscles/tendons, increasing the likelihood of running injuries.

Coaches around the world routinely use barefoot drills to improve running form. Newton Running has created the first natural running shoes for everyday training and racing that encourage barefoot running form. Join us in the Natural Running revolution.

Barefoot Running Goes Ballistic

Posted by on Thursday, January 28, 2010 @ 12:54 pm | 9 Replies

Barefoot running was one of the most talked about trends in the running industry last year. From the bestselling book Born To Run, to the explosive growth of the Vibram Five Fingers, runners everywhere seem to be talking about barefoot running.

Well, the buzz about barefoot running is about to hit a fever pitch. As we’ve talked about in previous posts, Harvard anthropologist Dan Lieberman has been studying the evolution of human running for several years. Dr. Lieberman has just published the results of his study in the journal Nature and the mainstream media is running (cough) with the story.

For those of you who listen to NPR on the drive home, you might have heard this story on “All Things Considered” today.  The story is also available on NPR.org and features a pretty interesting video:

Not surprisingly, Vibram Five Fingers are also getting a lot of attention from the media (Vibram sponsored Lieberman’s study). The Five Fingers clearly help people to try barefoot running, while providing some protection from rocks, glass, etc.

How do Newton Running shoes compare to Vibram Five Fingers?

As we talked about in the previous post, Newton’s are built for Natural Running but some of you may be wondering how Newtons compare to Vibrams. Amanda Brooks asked just that on her blog, Run to the Finish, and Newton Running’s Director of Education and Research, Ian Adamson, had this response:

“Running Newton Shoes and Vibram Five Fingers have many similarities, at least from a form perspective. The primary difference is the cushioning and energy return provided by Newtons, which is largely absent in Vibrams.

Newton Gravity Trainer: 3mm heel-to-forefoot drop / 2.0% gradient

Newton Gravity Trainer: 3mm heel-to-forefoot drop / 2.0% gradient

Both Newton Performance Racers and Vibrams have a 2 mm heel lift, or toe drop depending on how you look at it. This translates into a 1.3% gradient in the shoe, also referred to as ramp angle or drop. Newton Performance Trainers have a 2% gradient, which although very small, can be felt by aware runners. Regular running shoes have a much steeper angle, up to 15% depending on the shoe.

 

Asics Gel Kayano 15: 22mm heel-to-forefoot drop / 14.7% gradient

Asics Gel Kayano 15: 22mm heel-to-forefoot drop / 14.7% gradient


Barefoot running forces you to run efficiently and preventatively with respect to injury. Vibram’s allow people to experience barefoot running with an added layer of protection from harsh surfaces, while Newton’s go one step further, adding forefoot cushioning and  a significant energy return component.

Newton shoes are much kinder to the body’s structure and musculature when transitioning from a traditional running shoe to barefoot, and allow you to perfect a natural (barefoot) form while providing protection and cushioning.

Newton’s Action/Reaction Technology has been carefully designed to facilitate afferent feedback, which means the nerves in your forefoot feel the ground very quickly through the shoe. This is achieved through the outer lugs and internal semi-rigid chamber that is connected to the biomechanical top plate adjacent to your foot inside the shoe.

Traditional shoe cushioning mechanisms dampens afferent feedback, hampering proprioception and thus hindering your ability to self-regulate the impact of your foot strike. Studies show that runners strike much harder in cushioned shoes, one of the causes of injury. Running barefoot or in shoes that allow you to sense the ground encourage you to run protectively.”

Bottom line is that both Vibrams and Newtons encourage a barefoot or natural running style, but Newtons make it easier for most runners to transition their form after years of wearing ‘traditional’ running shoes.

Do Running Shoes Cause Injury? Our Response

Posted by on Tuesday, January 12, 2010 @ 12:00 pm | 15 Replies

Newton Running shoes are minimalist in that they have a heel-to-drop between 1 and 3%, depending on the model.

 

There’s a great discussion going on over at RunnersWorld.com about a new study that links running shoes to injuries here. Here are a few thoughts that our Director of Education, Ian Adamson, would like to add to the dialogue:

  • There are several on-going, multi-year studies at Harvard, MIT and the University of Newcastle (AUS) that are looking at injury related to footwear. Harvard department of Anthropology is about to publish a study that dissects unshod human running gait and injury (or lack thereof.)
  • If the only injury from running shoes is Achilles tendinitis, is the implication that the other “running related injuries” such as neuromas, plantar fascitis, blisters, bunions and joint problems would be present in if people didn’t run?

How Shoe Geometry Affects Running Gait

I’m on the front line seeing runners who present with all of the above and more, and the vast majority are treatable with appropriate shoes (the closer a shoe reflects the geometry of the foot the better, although protection from man-made and unnatural surfaces is prudent), especially a lower heel/ramp angle combined with proper form coaching.

There is no doubt in my experience (running competitively since 1973, 12 years as a professional athlete, 10 years in the shoe industry, 10 years as a bio-mechanical engineer) that lifted heels in running shoes introduce an unnatural geometry that interferes with our natural (and injury protective) gait.

Ramp Angle Comparison in Minimalist Shoes

It would take a lot to convince me that strapping 1/2 to 1″ foam to your heel doesn’t alter your stride. If you cut virtually any running shoe lengthwise you can see the drop from heel to the ball of the foot. The Nike Shox as noted above is one of the worst offenders. It used to be that 24 mm heel height (1 inch) and 12 mm (1/2″) forefoot was standard, but those numbers have changed dramatically in the last few years. Some popular running shoes are up to 35 mm in the heel.

The old standard drop (24-12) gives an 8% grade in a Men’s US size 9 shoe, but most are now far in excess of that, up to 15% in some cases. An 8% road grade (rise/ run as a %) is where most states give truckers a warning. Racing flats can be better in terms of being more level, but virtually none are actually level. The best on the market are:

It is interesting to note that some perceived “flat” shoes are not: Nike Free 5.0 (10 mm/6.7%), Nike Zoom Streak XC (11 mm/7.3 %), Nike Luna Racer (12 mm/8.0%), Brooks T6 (13 mm/8.7%). On the other end of the spectrum, the Brooks Beast has a 16 mm drop and 10.7% grade.

My personal experience: ran track and cross country barefoot and injury free through high school. Ran in Dunlop Volley tennis shoes through college (no heel lift http://www.volleys.com.au/flash/index.html), injury free. Was given a “modern” running shoe with a heel lift by a sponsor in 1989 and sustained my first running related injuries. Started back with level shoes again in 2007 (Newton) and viola, injuries gone.

Shoe Geometry 101 – Running Shoe Re-Evolution

Posted by on Wednesday, December 16, 2009 @ 12:00 pm | 7 Replies

By Danny Abshire, co-founder, Newton Running

At the start of the first American running boom in the 1970s, most people were running in fairly lightweight shoes that consisted of a rubber outsole a thin foam midsole and a lightweight nylon upper. Although simple by today’s standards, some of those early shoes were pretty good at allowing the foot to move naturally without the need for excessive muscular force and allowed a runner to obtain afferent feedback from each foot’s interaction with the ground.

As footwear technology advanced over the years, running shoes generally became cushier, softer, thicker, heavier and, in some respects even more comfortable. But, while some of the innovations were driven by performance, the end result in many cases was anything but performance-oriented. And that’s why, 30 years later, thousands of runners run with inefficient mechanics predicated on a heel-striking gait. Not only is that form not optimal for running fast, it can also lead to numerous overuse injuries.

The biggest culprit of modern running shoe design is that most training shoes have large, overbuilt heel crash pads that encourage and really only allow a heel-striking gait. Even if you wanted to run with a natural midfoot/forefoot stride pattern, the geometry and heel height of many shoes will not allow your foot to land naturally or parallel to the ground because the hefty heel gets in the way.

What is Natural Running?

Simply put, natural running is the way the human body was meant to run in its purest form - namely, barefoot – across a solid surface. That means running with efficient mechanics centered around landing lightly on the midfoot/forefoot (the ball of the foot, but not the toes) and quickly lifting your foot off the ground instead of pushing off with excessive muscular force.

In order to accommodate that style of running, a runner needs to be able to feel the ground and interact with it accordingly just as when barefoot.

And to do that, the runner needs to be wearing lightweight, minimally designed running shoes. The afferent feedback from feeling the ground encourages your body to run with light footsteps, upright posture, a relaxed arm swing and a slight forward lean.

That important feedback is obtainable via minimalist, lightweight running shoes designed to allow the foot to strike the ground with a natural midfoot/forefoot gait but is impossible to receive wearing thickly cushioned shoes and a heavy heel-striking gait. Practicing natural running form can be simple, but it may take time to unlearn old habits and learn proper technique. Ultimately, natural running can help make a runner stronger, more efficient and less prone to overuse injuries.

What Are Minimalist Shoes?

Minimalism in its simplest form involves picking shoes that allow the foot to move more naturally than standard shoes allow. But not all minimal shoes are created equal. Newton Running shoes were designed to be an extension of the feet, enhancing ground contact without the jarring impact shock of the road, sidewalk or hard-packed trail below.

Newton’s reduced heel height and sleek geometry allows the shoe to stay out of the way as it approaches the contact with the ground, and along with enhanced forefoot communication, allows the runner to strike lightly at the midfoot/forefoot instead of using a heel-striking motion that requires heavy breaking and excess muscular force.

Newton Running’s patented Action/Reaction Technology™ encourages natural running or a barefoot running gait and enhances the shock absorbency, leverage and energy return throughout the gait cycle, ultimately helping achieve a faster cadence and more efficient mechanics. Newton’s independent lab research shows the system returns up to 28 percent more energy and reduces impact up to 44 percent when compared to training and racing shoes offered by leading running brands.

Practicing natural running form can be simple, but it may take time to unlearn old habits and learn proper technique. But it also requires having the appropriate footwear to allow your body to run the way it was designed to run. Once you learn to run naturally, you’ll put yourself in position to run faster and healthier for the rest of your life.

Preventing Stress Fractures

Posted by on Thursday, December 3, 2009 @ 11:44 am | 4 Replies

Earlier this week, the New York Times published an interesting story about a common injury that many, many runners suffer from – stress fractures. The article references a new study published in the journal Medicine & Science in Sports & Exercise which, “offers hope that, at least for runners, simple alterations in their stride or in the strength of their legs might reduce their risk for the most common type of stress fracture.”

I’d encourage you to read the whole article, but here’s the most salient point:

“The researchers determined that reducing stride length by about 10 percent seemed to reduce the stress on the tibia enough to lower the risk of a stress fracture.

Why, though, should shortening your stride affect your tibia at all? “Think of it this way,” says Brent Edwards, lead author of the study and now a post-doctoral research fellow in the Department of Kinesiology and Nutrition at the University of Illinois, in Chicago. “If you spend less time in the flight phase of running” — meaning in the air — “you’ll hit the ground with less force.” On the other hand, you’ll hit the ground more often. But in Mr. Edwards’s models, the reduction in pounding from an abbreviated stride outweighed the shock from a few additional strides per mile.”

Shortening your stride is one of the key tenets of the proper running form that Newton teaches (see #3 on our 10 Laws of Running Better). Running coaches like Danny Abshire have known for years that over-striding can lead to injuries, and now it’s nice to have some empirical data to back it up.

Also, here’s a great image the Denver Post ran a few months ago that illustrates many of the benefits of proper natural running form.

“From heel striker to forefoot runner – Why I love my Newtons”

Posted by on Friday, July 10, 2009 @ 9:20 am | Leave a reply

We just came across this terrific post from Johnny Hammond, a 43-year-old age-grouper triathlete and runner in the UK. It’s an interesting story about his nagging running injuries and how his transition to forefoot running and Newtons has dramatically helped.

“At the beginning of my winter training this year, I started training with a new triathlon coach who wanted me to change my running style from heel striker to forefoot running. He said it would increase my speed and running efficency, and reduce my risk of injury. I was apprehensive at first and questioned his judgement.

I’d struggled with a left shin splint injury for the past 3 years and had gone to a lot of expense to get special orthotics and the right running trainers to try and ward off this recurring injury. But, I was still finding it hard to run longer distances without my shin splint (left tibia post to be precise) flaring up, so I decided to give forefoot running a go.

At first, I found it really hard to run on my forefoot without my heels dropping so my coach suggested that I invest in pair of Newtons, initially as a training aid. He told me that the Newtons would ‘put me up’ onto my forefoot and help me to progress from heel striker to forefoot runner.

I’d also heard the buzz about Newtons on the triathlon circuit and decided to find out what all the fuss was about. £120 later and I was sporting a pair of lightweight orange and white Newton Distance S trainers, a far cry from my bulky motion control Asics running shoes (also £100 plus shoes).”

The (Popular) Science of Newton

Posted by on Friday, March 6, 2009 @ 9:43 am | 4 Replies

Although he doesn’t actually test Newton shoes, Adam Weiner from Popular Science offers an interesting take on the science of Newton Running technology in this article, Will Barefoot Running Cure What Ails Us? I love his intro:

“First of all, let’s set the record straight. Man is a natural long distance runner. Despite impressions to the contrary foisted on us daily from our predominantly sedentary and ‘well-fed’ modern lifestyle, it is interesting to note that for long enough distances a well-trained human can outrun just about any other creature on the planet.”

Weiner then further evaluates:

“In fact, consider the following: Man evolved to run barefoot, and shoes arrived on the scene only in the last few tens of thousands of years or so. Try running barefoot some time (preferably on a softer surface like grass) and pay attention to your foot strikes. You might find that it’s almost impossible to land heel first. Your command central (your brain) just won’t let you do it. Too much jarring. Your bare heel isn’t designed to handle that pounding. The evidence supports that landing nearer the middle to front of the foot is the most efficient way to go.”

Check out the full Popular Science story here.  We’re going to try and get Mr. Weiner in some Newtons so he can actually try them for himself.
