Do Running Shoes Cause Injury? Our response. UPDATE

Tuesday, January 12th, 2010

Now MSNBC has posted about the new study as well.

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

  • In fact, 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?

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.

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:

  • Vibram (2 mm differential = 1.3%)
  • Newton Racer (2 mm/1.3%)
  • Newton Performance Trainers (3 mm/2.0%)
  • Newton Guidance Trainers (5 mm/3.3 %)
  • Asics Piranha 3 (6 mm/4.0%)
  • Biom (8 mm/5.3%)

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.

Study: Height of Heel Matters in Prevention of Foot Pain

Wednesday, December 23rd, 2009

Check out this interesting study published in the November issue of Foot & Ankle International (FAI), the official scientific journal of the American Orthopaedic Foot & Ankle Society (AOFAS). The study details the biomechanical changes that occur in feet during high heel wear and the correlation between the heel height and amount of pain, pressure and strain it puts on your feet.

The study was conducted on people walking, not running in high heels, but it’s reasonable to assume that the forces involved in running in a 1/2” heel lift are considerably higher than walking in more.

The study authors suggest limiting heel height as well as the use of padding at the ball of the foot can significantly reduce discomfort and risk of injury to the metatarsal heads.

Newton Racers have a 2 mm drop from heel to toe, the Performance Trainers are 3 mm and Guidance Trainers (Sir and Lady Isaac) are 5 mm. The typical running shoe has a heel lift of a 1/2 inch or more. You do the math.

Shoe Geometry 101 – Running Shoe Re-Evolution

Wednesday, December 16th, 2009

danny-abshireBy 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.

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.

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

Thursday, December 3rd, 2009

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.

Natural Running, Barefoot Running, Efficient Running (new article by Danny)

danny-abshireDevelop efficient form with lightweight shoes and barefoot drills

By Danny Abshire, co-founder, Newton Running

The natural running movement is quickly becoming a revolution. Are you onboard yet?

Thanks to the advancement of lightweight high-performance running shoes plus a best-selling book and recent stories in the New York Times, Los Angeles Times, Denver Post, Washington Post and National Public Radio, to name a few, the natural running movement has become quite the rage in recent months.

Natural running is running the way the human body was meant to run in its purest form — namely, barefoot — across a solid surface. That means running with good mechanics and a efficient gait that focuses on 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. Natural running can help make you a stronger, more efficient runner who is less prone to overuse injuries.

Tenants of natural running can be seen while running barefoot and running in lightweight or minimalist running shoes that allow your feet to develop proprioception or “feel” the ground with every step. Running barefoot on a soft lawn, wet sand or even a smooth sidewalk offers proof of your body’s natural inclination for moving across a surface with as little muscular force as possible. The same is true for minimalist running shoes on pavement, concrete or hard-packed trails.

That afferent feedback from feeling the ground encourages your body to naturally run efficiently with light footsteps, upright posture, a relaxed but consistent arm swing and a slight forward lean. Landing lightly at your midfoot/forefoot and quickly picking up your foot to start a new stride is the most effective way your body knows to propel and protect itself while running. Conversely, your body doesn’t allow you to land on your heels, especially if you’re running on a hard surface, because it isn’t engineered to accommodate the blunt force trauma of repeated heel striking. But that’s fine because landing with hard heel impacts doesn’t allow you to be efficient and run with good form.

Running barefoot in controlled circumstances can help you improve your natural running form while also strengthening smaller muscles in the feet, ankles and lower legs that are otherwise unused while running most contemporary running shoes. Many elite runners and triathletes regularly incorporate barefoot drills on soft grass surfaces into their weekly routine. However, it’s very important to implement barefoot running sessions in small doses so as not to become vulnerable to injuries caused by an over-reliance on propulsive muscles in the feet, calves and hamstrings or overstressing the plantar fascia and Achilles tendons.

Unfortunately, most contemporary running shoes have been designed for running form that encourages heavy heel striking and dampens the afferent feedback that allows the foot to sense the ground. 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 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.

Real Person Review: “From heel striker to forefoot runner – why I love my Newtons”

Friday, July 10th, 2009

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 tib 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).”

How to reduce and avoid common running injuries

Monday, June 22nd, 2009

danny-abshireEfficient form and lightweight shoes are the keys to staying healthy

By Danny Abshire, co-founder, Newton Running

Do you think a running shoe with a thickly cushioned heel pad and rigid medial post can keep you from suffering common running injuries such as plantar fasciitis, iliotibial band syndrome or shin splits? Think again.

Recent research and news reports are confirming what those close to the sport have known for years: running shoes with thick midsoles, extensive anti-pronation devices and large heel crash pads don’t prevent injuries.

The key to preventing running injuries is to run with lightweight shoes and efficient, low-impact running form. Running in heavy, overbuilt running shoes can put more strain on a runner’s body, reduce proprioception necessary to engage proper form and make a runner’s feet and lower legs overwork braking and propulsive muscles and connective tissue — a combination which can actually make a runner more prone to common overuse injuries.

A recent study at the University of Newcastle in Australia concluded there is no scientific evidence to support claims that running shoes with elevated heel crash pads and elaborate anti-pronation systems prevent injuries in runners. The findings have been published in the March 2009 edition of the British Journal of Sports Medicine.

“Since the 1980s, distance running shoes with thick, heavily cushioned heels and features to control how much the heel rolls in, have been consistently recommended to runners who want to avoid injury,” Dr. Craig Richards, one of the researchers, said in a press release announcing the results of the study. “We did not identify a single study that has attempted to measure the effect of this shoe type on either injury rates or performance. This means there is no scientific evidence that [those shoes] provide any benefit to distance runners.”

Dutch researchers have previously found that between 37 and 56 percent of recreational runners become injured at least once each year. The most common maladies are found in the feet and lower legs, but others include pelvis and lower back injuries.

“Not only can we no longer recommend a shoe [with an elevated heel and pronation control system], but the lack of research in this area means that we cannot currently make any evidence-based shoe recommendations to runners,” Richards said in the release. “To resolve this uncertainty, running shoes need to be tested like any other medical treatment, in carefully controlled clinical trials.

“This will ensure that only running shoes with proven benefits can be marketed and sold as therapeutic devices. Until this occurs, health professionals will not know whether the distance running shoes they are recommending are beneficial, harmless or harmful.”

A recent story in the London Daily Mail confirmed what the Australian report suggested in an excerpt from a new book called “Born to Run” by journalist Christopher McDougal. That story referenced Dr. Daniel Lieberman, professor of biological anthropology at Harvard University, who offered the startling conclusion that: “A lot of foot and knee injuries currently plaguing us are caused by people running with shoes that actually make our feet weak, cause us to overpronate (ankle rotation) and give us knee problems.”

To run efficiently, you have to understand your body and how it naturally moves across a surface with as little muscular force as possible. The tenants of good running form include running with short strides and a quick cadence, landing lightly on the midfoot/forefoot area (the ball of the foot, but not the toes), and quickly lifting your foot off the ground instead of pushing off with excessive muscle force. A slight forward lean and a relaxed arm swing are also key components.

To illustrate what Newton Running calls the “Land-Lever-Lift” technique, take the simple test of running barefoot across a smooth floor. More than likely, you’re naturally going to land lightly at your midfoot/forefoot and quickly pick up your foot to start a new stride. Your body doesn’t allow you to land on your heels because it isn’t engineered to accommodate the blunt force trauma of repeated heel striking. Unfortunately, most contemporary running shoes have been designed for running form that demands heavy heel striking and dampens the afferent feedback which allows the foot to sense the ground.

Two of the biggest mistakes distance runners can fall prey to are 1) excessive heel striking that causes abrupt braking of forward momentum, and then pushing off too hard with the toes to start the forward motion again; or 2) using only propulsive muscles,(the calf group, hamstrings and Achilles tendon) by running too far up on their toes like a sprinter and not using the body’s natural cushioning system. Each of those form flaws puts too much vertical movement into every stride, and that leads to inefficiency and considerably more impact, muscle and tendon stress on the body.

The photo pretty much says it all. Craig Alexander overcame a five-minute deficit on the run at the Ironman 70.3 Boise on Saturday, beating Chris Lieto by just two seconds in a final 50-yard dash.  Check out Crowie’s near-perfect, aligned form as he passes Lieto in this photo.

The Idaho Statesman has a recap of the race here as well as an incredible series of photos from the finish sprint here. It’s awesome to see such terrific sportsmanship from both competitors (and gratuitous Newton shoe shots). Crowie said it was one of the most excited races he’s ever been a part of.

Congrats to Crowie!
