How to Read and Interpret the Wear Pattern on Your Running Shoes
http://runnersconnect.net/running-tips/read-wear-pattern-running-shoes/

Running Ugly Sometimes Wins Marathons.

There are many running gurus out there. There are numerous running form clinics out there.  Everyone knows someone that can tell you how to run better and show you things you should be doing to improve your running.  But should you listen ?  That is the problem, should we listen ?  There is the old adage that “if it ain’t broken, don’t fix it”.  Sometimes that is true as well. But lets face a fact, most people that come into our offices do not come in with the request to make them a better runner, rather they come in asking us to help them resolve a problem or injury that is stopping them from becoming a better runner.  

In this video, the two elite runners are clearly not made from the same mold.  There is no question, even to the uneducated eye, as to who is the more comfortably appearing and “cleaner” runner.  The fella in the orange represents much of what we are all told a runner should look like posturally.  But, it is clear that the fella in the blue is having no problems keeping a comfortable stride with the guy in the orange even though is form looks labored from a postural stand point.  But remember what we always say, what you see in someone’s gait is quite often not their problem, it is their compensation to cope with a problem.  And compensations are needed because we are all never 100% clean and biomechanically efficient. Back to our point, telling Mr. Blue to retract his head and lift his chest may not be what the run doctor ordered.  Changing this one glaring fact could be the thing that injures him or reduces his efficiency amongst other things.  Just because you don’t like what you see doesn’t mean it is wrong for that person or that it needs to be changed. This is why a clinical examination along with a gait analysis is imperative for solid advice. For example, what if this guy has a scoliosis or some other structural problem that has made his thoracic spine more kyphotic  thus producing a more accentuated cervical lordosis and an extended and protracted head carriage ?  Changing in this case that posturing may not be possible for him or may create problems elsewhere.  AGain, just because you do not like it doesn’t mean you should change it.  

So the next time you are at your local store or some marathon event tent and getting form running advice from an “expert”, take it with a grain of salt because there are so many pieces of the puzzle that they are not seeing or understanding.  This is the big problem with the internet and all of its guru’s and their advice.  The next time someone says, here is our go to video for resolving shin splints, take it with a grain of salt. Even if it is us giving the advice on one of our podcasts, because without the examination probably 90% ?? of the information is absent.  If you make a change in someones form, there must be a reason and a goal and you must be prepared to catch any fall out from those changes and know what to do with them.  This is where clinical experience comes in.  So the next time your favorite running site or running magazine gives what appears to be sound advice for chronically tight IT bands, think it over, take it with a grain of salt, and make a sound judgement based on what your body is doing with its unique limitations and pay attention to the results and possible positive and negative outcomes.  Change is inevitable, but is it good for you ?  That is the question.

Oh, and by the way,these were the marathon’s leaders, Benjamin Bitok and Nixon Machichin, both of Kenya. Bitok (in blue) went on to win in 2:13:21, 46 seconds up on Machichin.  

It just goes to prove that what good running looks like ,and should be better in our perfect little world, and of what the websites and magazines tell us about what is right, doesn’t always lead to improved performance.  However, we wouldn’t suggest you start running with Bitok’s form because he is awesome (even though some kids in his home land may do just that because modeling is the greatest form of compliment.)  But, what do we know ? We are just two more self-proclaimed guru’s trying to set the record strait, from our experience and perspective.

Hi Gait Guys – amazing wealth of info you’ve provided! I’ve been suffering from severe foot pain (peroneal tendonitis and general top/side foot pain) for about a year now which has turned me from very active to completely sedentary since I can hardly walk. My ortho gave up on me after 9 months of treatment incl. countless oral and injected steroids and 2 months in a boot. Then this morning I found your site – and the “The Gaits of Hell” video. That’s my walk!! Is it really all in my back?

8. Why Where You Land On Your Foot Isn’t That Important

http://www.kinetic-revolution.com/why-where-you-land-on-your-foot-isnt-that-important/

Classic Crossover Gait Case.

Here is a client with a uncompensated forefoot varus (ie: the forefoot is inverted with respect to the rearfoot) and a cross over gait, secondary to incompetence of the medial tripod of the foot (he cannot descend the head of his 1st metatarsal to form the medial tripod due to the uncompensated forefoot varus) and weak right lower abdominal external obliques which we discovered on examination (perhaps you can detect a subtle  sag of the right side during stance phase on that side).

Note how he circumducts the lower extremities around each other. This takes the cross over to another level and it can occur when a client is pronating through the medial tripod such as in this forefoot varus case (we know this from the examination, it cannot be detected for sure from the video with the foot in the shoe, that would be an assumption).

How do you fix this?

  • tripod standing exercises
  • core stabilization exercises with attention to the right lower oblique (see our core series available for download on Payloadz here and here
  • foot manual therapy to improve motion of the 1st ray
  • see our crossover gait series on youtube here: part 1, part 2, and part 3
  • form running classes such as Chi Running

The Collective Goal of Natural Running. The Gait Guys Opinion.

Is this minimalist shoe trend a fad or is it truly a trend? What is the truth. (What are you not being told ?)

It appears that over the last few years this question is finding its own answer, for the most part.

We believe this minimalist direction has become entrenched enough now seeing the increased work and attention from most companies. We suspect that this is a firm trend which will not be going anywhere soon, although modifications will be likely. The research papers are convincing that there are benefits. However, we feel the industry is not spending enough time discussing the risks and concerns. And we are finding out that there are two issues here on that topic.

1. That discussing the demerits of a product is not likely good marketing.

2. One must know the underlying problems around the product, and more importantly the foot that is going into the product to understand a product’s drawbacks and risks.

None the less, there are issues not being talked about.

The fact of the matter is that some foot types do not, and never will, have any business being in such minimalistic shoes (ie. a rigid flat foot pes planovalgus or a rigid forefoot varus foot type are just a few examples). We remain concerned about the vague existing dialogue that these types of shoes will make everyone’s feet stronger. For some, they will, but many times strength education must be directed (There is a right way to do a squat, and a wrong way. There is a right strategy for toe off, and a wrong one.). With the wrong strategies employed, one can easily strengthen the incorrect motor patterns. Merely putting on a minimalistic shoe does not mean that the correct patterns and strategies for foot strengthening are being instituted. The shoes do not come with a magic potion guarantee. For those with challenged foot types (FF varus, Rothbart Foot, cavovarus foot, excessive tibial varum and/or tibial torsion etc) these folks will likely trend towards local foot problems or injuries further up the kinetic chain (hip, knee, low back etc). Understandably, these are heavy medical terms and conditions but they are very much out there in the running public and with little attention to the “buyer beware” warning when attempting to add a minimalist shoe to their mix. We know these issues exist, we see them daily in our clinic. As we see it, the problem could be that those providing the education often do not have enough clinical background to know what these issues are let alone recognize them or prescribe the right shoe for the combined presentation . So how can they then draw these issues to the surface in educating the public ? As we say in our lectures, “You first have to know what a platypus is in order to identify it. Otherwise it is just a hedge hog with flippers and a duck bill.” This is the elephant in the room that everyone is missing, everyone except us. We get the folks who are running in these minimalist devices and we get to see those who should never have been in them in the first place.

The good thing is that many companies are setting up educational programs to help folks drop down into “minimalism 2.0”. But still, to date, two problems exists in that arena.

1. no one is talking about the elephants in the room, those being those foot types that are too risky to be in the shoes and even more specifically, how to strengthen the foot. But who would admit to those risks, that would be stupid advertising.

2. those teaching the courses and those individuals that rep for the companies and act as an intermediary between the shoe company and the store either do not have the fundamental knowledge to educate the shoe stores about the merits and demerits of the products or they find there is too much of a knowledge gap between the parties so things are left unspoken. You have to be able to see the elephant in the room to address it.

It is at the heart of these issues that we feel we can make a difference. A few companies are finally listening to us on these topics. We are getting more calls, emails and inquiries as to how we can help them bring these issues to light and improve upon their products. Sadly, most companies are not doing the same and we feel they will be left behind. Companies are sharing exciting yet difficult challenges and many are struggling to catch up. Some of them are really on board and doing their homework and are coming to the table with really impressive dialogue. We are excited to work closely with these types of companies so that all runners can reap the safe and effective benefits of better products and more knowledgeable intermediaries. These companies, some big, some small, get a big thumbs up from us because the knowledge behind the product is spot on but more so because the product is excellent and does what it says it is supposed to do and goes beyond what the other products seem to be doing at this point. But there is always someone around the corner pushing the guys at the front.

Our one ‘stick in the mud’ issue is that still no one is talking about the elephants. And we believe its mostly because no one can see them. There is a main danger in doing too much barefoot running too soon. We made this clear initially on Vibram’s website when we wrote the part on how to progress out of your running shoe and down into Vibrams. For us it is, and has always been, about “keeping them honest” and putting out the facts. But don’t expect us not to make mistakes, nor to not own up to them. But do expect us to try to “right the wrongs”. From time to time we try to make the calls on the products that have questionable statements and applaud those that stick their neck out to do the right thing. We do not know everything, but we seem to know much more than many when it comes to the biomechanics of what is going in a product and in knowing when there is a giant tusked animal in the room.

If you put 10 different feet in a product, you will get 10 different biomechanical presentations from the shoe, and that is the difficult truth. So, logically, much of what is being missed is the education of that issues and of what is going on in the shoe, and that is our world. It is usually the problems that exist with the thing you are putting into all of these products, a person. A person who likely does not have the classic middle of the road, ‘Average Foot’ these shoes may have been designed and researched around.

To us, the most important thing is to raise the knowledge and awareness to the public, shoe companies, shoe stores and everyone else in between.

At this point, if this minimalist shoe trend is to survive we believe there must be enough companies that extol the virtues of honesty and education to the end user, the shoe company-shoe rep intermediaries, running form clinic presenters and educators. And, that means talking also about the elephants in the room. Our new, soon to launch, Shoe Fit Educational Program will help everyone get on the same page, and the same elephant.
