Les défendeurs de la chaussures moderne/ Modern shoes defenders

English follows

Peu de scientifiques ou de professionnels de la santé défendent encore les chaussures de jogging modernes (big sulky shoes, chaussures technologiques maximalistes). Un des plus tenaces, mais attention connaisseur en la matière, Kevin A. Kirby, Podiatre (Adjunct Associate Professor, Department of Applied Biomechanics, California School of Podiatric Medicine) continue de s’exposer comme un fervent défenseur du maximalisme. J’ai connu Kevin sur les blogues tels que Podiatry Arena et Podiatry Today, et je dois dire que ses connaissances élaborées sur les questions entourant la chaussure de course à pied en font un coriace débatteur. Je ne suis pas d’accord avec certaines de ses opinions, mais respecte l’homme et les idées qu’il défend scientifiquement.

Kevin a récemment publié un article sur http://www.podiatrytoday.com/barefoot-versus-shod-running-which-best et avait déjà exposé « les 10 faits que les défenseurs de la course pied nus ne parlent jamais ». Voici nos réponses en bleu!

Kevin A. Kirby : Voici quelques faits qui semblent n’être jamais mentionnés par les défendeurs de la course pieds nus :
1. Tous les records mondiaux actuels sur piste, route et cross-country ont été faits en chaussures et non pieds nus.
R: Avec des chaussures très minimalistes pour 90% de ces records. (zéro dénivelé pour les « spikes » (pointes), tous très légères, aucun support pour toutes ces chaussures, …)

2. Aucun marathon international n’a été gagné par un coureur pieds nus (courant la course entièrement pieds nus) depuis plus de 50 ans.
R: C’est la preuve que l’homme moderne est complètement accro aux chaussures et à un certain degré de protection… Ce n’est pas la preuve que c’est meilleur.  (Même parallèle avec l’obésité… normalité et généralité ne veulent pas dire meilleur! 60% des Nord-Américains ont un surpoids pondéral… et ce n’est pas une chose que je recommande.)

3. La « chaussure minimaliste » n’est rien de nouveau et a toujours été disponible dans les magasins de chaussures de course depuis les 40 dernières années et se nomment des « racers ».
R: Oui mais les vendeurs de chaussures les recommandaient seulement aux jeunes coureurs rapides et légers… 3% de la population des coureurs… et 3 % des ventes il y a 2 ans et plus. Une chance que la mode du « minimalisme » change les pratiques, et permet enfin une plus grande ouverture d’esprit des détaillants!

4. Abebe Bikila a gagné le marathon Olympic de Tokyo en 1964 en brisant le record du monde en un temps de 2:12:11, en chaussures, en courant 7 secondes de mieux par mile que ce qu’il avait fait au marathon Olympic de Rome en 1960 qu’il a couru pieds nus.
R: Oui et 4 ans plus tard il était blessé (fracture de stress causée par une attaque talon engendrée par ses chaussures? Qui sait? I’m just guessing :) ) . Vous pouvez comparer les performances sur piste… mais pas comparer des marathons différents (conditions environnementales, côtes…).

5. Zola Budd, qui a brisé le record du monde au 5000 mètres en courant pieds nus, préfère maintenant les chaussures en disant: « Je ne cours plus pieds nus. En vieillissant, j’ai eu des blessures aux  ischio-jambiers. J’ai découvert que porter des chaussures me donnait plus de support et protection contre les blessures. »
R: Opinion personnelle et peut-être fausse idée… Certains coureurs ont débuté le pied nu pour les mêmes raisons avec succès! Croyez-vous que la chaussure diminue le stress sur l’ischio-jambier? Croyez-vous que les chaussures coussinées diminuent le stress sur une autre partie que le pied lui-même et la partie postérieure de la jambe?

6. Une chaussure à orteils séparées et à semelle mince comme une Vibram Five Fingers n’a rien de nouveau. Le Marathon de Boston de 1951 a été gagné par le coureur Japonais Shigeki Tanaka qui portait une chaussure à orteils séparées et semelle mince faite par Onitsuka Tiger (maintenant ASICS)
R: Aucun commentaire… où est le problème?

7. Six recherches scientifques publiées dans des revues scientifiques (examinées par des pairs) montrent que la course pieds nus augmente la vitesse de la force d’impact (vertical loading rate) comparée à la course en chaussure (Dickinson, 1985; Komi, 1987; Lees 1988; Oakley, 1988; DeClercq, 1994; DeWit, 2000).
R: Vous oubliez Cole-1995, De Koning-1993, McCarthy-2011(UP), O’Leary-2008 pour votre hypothèse… Mais aussi d’autres études montrant l’inverse  (Lieberman 2010, Divert 2004, Hamill 2011)
La plupart de ces études montrant une augmentation de la vitesse de force d’impact -VLR- pieds nus sont faites avec des coureurs habitués de courir en chaussures… qui courent soudainement pieds nus… avec quelques essais sur un court corridor (20 à 30 mètres)… avec souvent aucun changement (ou pas assez) dans leur biomécanique (ces coureur continuent, volontairement ou non, la majorité du temps, d’attaquer du talon)
Les coureurs habitués à la course pieds nus ont clairement moins de « vitesse de force d’impact » -VLR- (Lieberman 2010, Squadrone-2009)

8. La course pieds nus provoque une augmentation de l’accélération tibiale (McNair PJ, Marshall RN: Kinematic and kinetic parameters associated with running in different shoes. Br J Sp Med, 28:256-260, 1994).
R: Encore ici une seule et unique étude avec 10 sujets habitués de courir en chaussures… ne changeant que subtilement leurs kinématiques durant les tests, entre les conditions pieds nus et avec chaussures. Pourquoi ne pas nommer ‘Shorten 2002′ (revue de littérature) ou Kerrigan 2009 (chaussures augmentent le ‘joint torques’ aux genoux et hanches) ou ‘Braunstein 2010, Shakoor 2006, Bergmann 2010′ (chaussures augmentent le stress sur le genou) ou autres utilisant des extensomètres, des puces intra-articulaires, des accéléromètres, … et montrant des résultats différents (Rethnam 2011, Hamill 2011, Lieberman 2010, Bergmann 2010, Divert 2004, 1996 Hennig)?

9. Le meilleur chercheur au monde en biomécanique de course et en biomécanique de chaussure de course, Dr. Benno Nigg, a fait une étude prospective qui a conclu qu’il n’y avait aucune différence significative sur l’incidence des blessures en course à pied entre des sujets avec une haute-, moyenne-, basse- force d’impact et que les sujets avec une haute force d’impact avaient de façon significative moins de blessures reliées à la course comparé aux sujets qui avaient une moins grande force  d’impact (Nigg BM. Impact forces in running. Current Opinion in Orthopedics, 8(6):43-47, 1997). Dr. Nigg mentionne de plus : « actuellement, il n’y a pas de preuve concluante que la force d’impact durant la course talon-orteil est responsable du développement de blessures reliées à la course à pied. » (Nigg BM: Biomechanics of Sports Shoes. University of Calgary, Calgary, 2010. p. 32.)
R: Je suis partiellement en accord avec Nigg… mais à nouveau nous devons considérer toutes les autres études sur ce sujet surtout si publiées après la date de publication de son livre (2011-Zadpoor, 2010-Davis(UP)… and 2006-Millner, 2006-Dixon, 2005-Zifchock, 2005-Divert, 2005-Dallam, 2005-Hreljac, 2004-Arendse, 2003-Mercer, 2000-Hreljac, 2000-Razeghi, 1995-Nigg). Juste pour votre information, les conclusions de Dr Nigg sont aussi sur la non-efficacité de l’absorption des chaussures à prévenir les blessures! 

10. La course pieds nus augmente la rotation tibiale interne comparé à la course en chaussures… Ceci suppose que la pronation de l’arrière-pied et les blessures associées à la pronation excessive de l’arrière-pied peuvent être augmentées par la course pieds nus (Eslami M, Damavandi M, Allard P: Foot joints and tibial kinematic coupling patterns during stance phase of barefoot versus shod running. J Biomech, 39:S183, 2006.
Fukano M, Nagano Y, Ida H, Fukubayashi T: Change in tibial rotation of barefoot versus shod running. Footwear Science, 1:19-23, 2009.)
R: Pure correlation… pas de causalité! La pronation et la rotation tibiale interne ne sont pas une cause claire de blessures (2009(RS)-Barton, 2009(SR)-Zammit, 2008-Grau, 2008-Donoghue, 2008-Srcevic, 2007-Wilson, 2006-Cheung, 2005(R)-Hreljac, 2005(R)-Knutson, 2002(R)-Gurney, 2001-Nigg, 2000-Hreljac, 2000-Razegi, 1998-Hintermann, 1997-Wen, 1997-Stergiou, 1994-Hintermann) et quelques auteurs pensent que la chaussure augmente la pronation (Stacoff-2001, Hamill-1992, Heil-1999) et peut changer l’alignement du genou (Radzimski(RS) 2011, Chen 2010, Kerrigan 2009, Burkett 1985, Chen 2010).

11. Il n’y a aucune étude scientifique qui démontre que la course pieds nus ou en chaussures minimalistes réduit le risque de blessures. Cependant, le taux de fractures de stress au niveau des métatarses chez les coureurs faisant la transition vers la course pieds nus ou vers la chaussure minimaliste (comme les Vibram Five Fingers) est alarmant.
R: Alarmant? On utilise des cas anecdotiques sans preuve scientifique (sauf une étude à 2 sujets : Giuliani 2011) pour détourner l’attention du fait que la promotion des chaussures modernes, technologiques et maximalistes (90% du marché) n’est supportée par aucune littérature scientifique montrant un bienfait quelconque dans la prévention des blessures. Ceci dit, je suis d’accord qu’une transition trop rapide vers le minimalisme ou le pied nu est risquée pour les tissus fragilisés par le port fréquent des chaussures modernes maximalistes.

Very few scientists or health professionals still defend modern running shoes (big bulky ones). However, a one of them is a very tenacious, but good expert in the subject; Kevin A. Kirby, Podiatrist (Adjunct Associate Professor, Department of Applied Biomechanics, California School of Podiatric Medicine) keeps exposing himself as a fervent modern running shoes advocate. I know Kevin from blogs like Podiatry Arena and Podiatry Today, and I have to say that his elaborate knowledge on questions surrounding running shoes make him a great debater. I don’t agree with some of his opinions but I respect the man and the ideas he scientifically defends.

Kevin recently published an article on http://www.podiatrytoday.com/barefoot-versus-shod-running-which-best and already had exposed « the 10 facts that barefoot running defenders never speak about ». Here are our answers in blue!

Kevin A. Kirby:
Here are some facts that the barefoot running advocates seem to never mention:

1. All the current world records in track, road racing and cross-country were set, not barefoot, but in shoes.
A : With very minimalist shoes for 90% of them. (zero-drop for spikes, very light and no support for all these shoes)

2. No international marathon has been won by a barefoot runner (running the whole race barefoot) for the last 50 years.
A: That’s a proof that modern men are completely addicted to shoes and to a certain degree of protection… it’s not the proof that it’s better (Same parallel with obesity… normality and generality don’t mean better… 60% of north-Americans are overweight… and it isn’t something I recommend.)

3. « Minimalist shoes » are nothing new and they have been continuously available in running shoe stores for the past 40 years. They were called « racing flats » for the past40 years.
A: Yes, but the running shoe retailers recommend this type of shoe only to the skinny fast young runners… 3% of the runners and 3% of sales up until 2 years ago. Good thing that this new trend of « Minimalism » is changing minds, and is allowing for a better open-mindedness from retailers!

4. Abebe Bikila won the 1964 Tokyo Olympic Marathon, breaking the world record in a time of 2:12:11, while in shoes, running 7 seconds per mile faster than he had in the 1960 Rome Olympic Marathon where he ran barefoot.
A: Indeed, and 4 years later he was injured (stress fracture caused by his new heel strike pattern induced by the shoes? Don’t know… just guessing :) ) . You can compare track performance… but not different marathons (environmental conditions, hills, …).

5. Zola Budd, who broke the women’s 5,000 meter world record while barefoot now prefers shoes saying: “: “I no longer run barefoot. As I got older, I had injuries to my hamstring. I found that wearing shoes gives me more support and protection from injuries.”
A: Personal feeling and maybe misconception… Some runners successfully switched to barefoot running for exactly the same reasons! Do you think that shoes decrease mechanical stress on the hamstring? Do you think that big bulky shoes decrease the stress on any other part of the body than the foot and the lower part of the leg?

6. Split-toe, thin-soled running shoes, such as the Vibram FiveFinger are nothing new. The 1951 Boston Marathon was won by a Japanese runner, Shigeki Tanaka, wearing a split-toe, thin-soled running made by Onitsuka Tiger (now Asics).
A: No comment… what’s the problem?

7. Six scientific research studies published in peer-reviewed journals show that barefoot running increases the vertical loading rate -VLR- compared to shod running (Dickinson, 1985; Komi, 1987; Lees 1988; Oakley, 1988; DeClercq, 1994; DeWit, 2000).
A: You forgot Cole-1995, De Koning-1993, McCarthy-2011(UP), O’Leary-2008 for your assumption … but also other studies saying the opposite (Lieberman 2010, Divert 2004, Hamill 2011). Most of the studies showing an increase of VLR are done with runners used to shod running…suddenly running barefoot… few trials on a short runway of 20 to 30m… with often no change (or not enough) in their biomechanics (most of the time, these runners, keep heel striking, voluntarily or not). Runners used to run barefoot have clearly less VLR (Lieberman 2010, Squadrone-2009).

8. Barefoot running causes increased tibial acceleration (McNair PJ, Marshall RN: Kinematic and kinetic parameters associated with running in different shoes. Br J Sp Med, 28:256-260, 1994).
A: One more time, a single study with 10 people used to shod running… with small and subtle kinematic differences between barefoot and shod conditions. Why not to name ‘Shorten 2002′ (review) or ‘Kerrigan 2009′ (shoes increase joint torques at the knee and hips) or ‘Braunstein 2010, Shakoor 2006, Bergmann 2010′ (shoes increase stress on the knee) or other studies using extensiometers, intra-articular chips, accelerometers,… and showing different results (Rethnam 2011, Hamill 2011, Lieberman 2010, Bergmann 2010, Divert 2004, 1996 Hennig).

9. The world’s leading researcher in running biomechanics and running shoe biomechanics, Dr. Benno Nigg, did a prospective study that found no significant differences in frequency of running injuries between subjects with high-, medium-, or low-impact peaks and that subjects with higher loading rates had significantly fewer running-related injuries when compared to subjects with lower loading rates (Nigg BM. Impact forces in running. Current Opinion in Orthopedics, 8(6):43-47, 1997). Dr. Nigg further claims that “Currently, there is no conclusive evidence that impact forces during heel-toe running are responsible for development of running-related injuries.” (Nigg BM: Biomechanics of Sports Shoes. University of Calgary, Calgary, 2010. p. 32.)
A: I agree with most of Nigg’s statement… but still we need to consider all the other studies on that topic, especially those made after the publication of his book (2011-Zadpoor, 2010-Davis(UP)… and 2006-Millner, 2006-Dixon, 2005-Zifchock, 2005-Divert, 2005-Dallam, 2005-Hreljac, 2004-Arendse, 2003-Mercer, 2000-Hreljac, 2000-Razeghi). Just for your information, the conclusion of Dr Nigg is also suggesting the non-effect of shoe cushioning to prevent injuries.

10. Barefoot running increases internal tibial rotation vs shod running, meaning that rearfoot pronation and injuries associated with excessive rearfoot pronation may be increased in barefoot running (Eslami M, Damavandi M, Allard P: Foot joints and tibial kinematic coupling patterns during stance phase of barefoot versus shod running. J Biomech, 39:S183, 2006.
Fukano M, Nagano Y, Ida H, Fukubayashi T: Change in tibial rotation of barefoot versus shod running. Footwear Science, 1:19-23, 2009.)

A: Pure correlation… not causation! Pronation and internal tibial rotation are not clear causes of injuries (2009(RS)-Barton, 2009(SR)-Zammit, 2008-Grau, 2008-Donoghue, 2008-Srcevic, 2007-Wilson, 2006-Cheung, 2005(R)-Hreljac, 2005(R)-Knutson, 2002(R)-Gurney, 2001-Nigg, 2000-Hreljac, 2000-Razegi, 1998-Hintermann, 1997-Wen, 1997-Stergiou, 1994-Hintermann). Some authors think that shoes increase pronation (Stacoff-2001, Hamill-1992, Heil-1999) and can change the knee alignment (Radzimski(RS) 2011, Chen 2010, Kerrigan 2009, Burkett 1985, Chen 2010)

11. There is not one shred of scientific research that shows that running barefoot or running in minimalist shoes reduces the risk of injury. However, the rate of stress fractures in the metatarsals is alarming of those runners who switch to running barefoot or running in “minimalist shoes”, such as the Vibram FiveFingers.
A: Why alarming? Anecdotic cases without scientific evidence (except a study on 2 subjects: Giuliani 2011) are used to draw attention away from the fact that promoting modern running technologic and maximalist shoes (90% of the current market) is not supported by any scientific evidence showing their benefits in preventing running injuries. That being said, I am convinced that a too quick transition towards minimalism or barefoot running can be harmful for tissues weakened by frequent wearing of modern maximalist running shoes.

    Ajout au point 5:
    L’article que site le doc date de 2005 (aussi, peut-on penser que Mme Budd a eu par période des commanditaires très vorace et généreux pour qu’elle porte leurs souliers?). Voici un article de 2012:

    Zola Budd Gears Up For Comrades
    By News
    Published Apr. 25, 2012
    Updated Apr. 25, 2012 at 9:45 AM UTC

    She continues to back barefoot running.

    In the 80s, she was one of the world’s fastest middle-distance runners, often competing barefoot. Nowadays, Zola Budd is setting her sights on something else: one of the toughest ultra marathons in the world: Comrades.

    Comrades is 89K in length and ends in the South African city of Durban.

    Budd, who used to race barefoot decades before the movement gained traction, remains a strong advocate for shoeless walking and running.

    “If you look at athletes from Africa, the way we grew up in Africa was going barefoot,” she says. “It’s acceptable. I think it’s only in the U.S. and Europe where people are frowned upon if they go barefoot. Even my kids went to school barefoot.”

    Budd, who lives in the United States, is perplexed about attitudes towards barefoot running.

    “In the United States my kids are stuck in shoes because they are not allowed to compete at school level barefoot in any athletics event, which is quite strange to me,” she admits.

    2. Aucun marathon international n’a été gagné par un coureur pieds nus (courant la course entièrement pieds nus) depuis plus de 50 ans. C’est la preuve que l’homme moderne est complètement accro aux chaussures et à un certain degré de protection…
    Je ne trouve pas que c’est vraiment une preuve…
    3. Malheureusement, les pratiques ne changent pas tant que cela. À l’échelle régionale, oui, mais aux États-Unis, si on enlève la Nike Free (pas si minimaliste que cela), les ventes de chaussures minimalistes n’ont pas augmenté : http://www.runblogger.com/2012/05/state-of-running-shoe-market-first.html

      2. D’accord… preuve n’est pas le bon mot… mais je garde le reste de ma phrase :)
      3. Je reste optimiste. Je pense que le minimalisme (racers et autres chaussures minimalistes) vont représenter plus de 50% du marché d’ici quelques années. Les Free 3.0 sont tout de même acceptables pour moi.
      11. L’étude de Buist montre simplement que la règle du 10% d’augmentation de volume par semaine n’a pas de valeur scientifique pour les coureurs de leur étude (probablement applicable à l’ensemble de la population des coureurs). Ceci dit, les études sur l’adaptation des tissus au stress mécanique (ou la non tolérance au stress trop élevé) abondent. Les lois de la nature restent toujours les mêmes.

        I agree, in theory, that the best rinnung shoe is no rinnung shoe but in most cases we have a lifelong history of wearing shoes so our feet muscles are not what they would be if we had never ever worn shoes. Running barefoot or in a minimilistic shoe is all well and good but in most cases we have years of muscle atrophy to solve before reaching the nirvana of actually rinnung barefoot. And what happens after we have done our 20 minute to 1 hour run, what do we do do? Yes we put our restrictive shoes back on that counter act much of the good we have achieved with our wonderful new minimiistic shoes! I have discussed this problem online with top rate physical trainers such as Gray Cook, Scott Grisewood and Rob Burke, all are well known in their field of expertise and they all say the same thing; exercise your foot all day so that your foot is strong when you go and train. It is these 3 so called experts that got me wearing an insole product called Barefoot Science. Supposedly the infamous Benno Nigg has tested the product and also confirms that it is the only product that alters positively the state of intrinsic muscles in the foot. All I can say is that my foot shape has changed since wearing them. I now have a defined arch instead of a flattish foot!. My knee and lower back issues have totally disappeared and wearing my different types of minimilistic shoes is way more comfortable. On the subject of minimilistic shoes I have an assortment, Vibrams, Fila, Terra Planna and even bought a pair of ZEM Gear that i picked up at the recent Surf Expo show. Vibram are the least comfortable. The person(s) who developed this product were more interested in fashion rather than anatomy. My size 10 foot is going to have toes that are either shorter or longer than another persons size 10. No wonder they are uncomfortable. The best of the bunch is ZEM Gear but by the time I have run 10k the tread is gone. Terra Planna is the best for longevity but still, they don’t last that long sadly. My experience and suggestion is before going minimilistic or barefoot try strengthening your feet muscles first. Apologies to all for my long blog but I have finally found a subject that gets me passionate.

    I would so much prefer to read critiques that aren’t laced with attitude from both sides. I am a professional that is open to the research on either side and am also interested in clinical evidence as well as evidence-based research. It took 30 years of evidence-based research to be able to prove that cigarettes caused lung cancer amongst other things. Arguing about each study as they come in just distracts us all from doing what’s best for each patient. The whole story will take years more of research. I also find the whole discussion of barefoot running or shod running compartmentalized. Each runner has a life outside of running.
    If I have a patient who is a surgical room nurse (ie. hours of standing on concrete at a time) who grew up in controlled shoes in our western culture, who does 12 hour shifts, who has a house and kids to care for, who carries an extra 15 lbs on her frame, and who became injured since running…is it really the running (whether shod or not) that is injuring her?
    Conversely, if I have a patient of African or Asian origin who grew up without wearing shoes (likely not on concrete!) and who now has started running with a strong, stable, flat foot, but who has the identical life responsibilities as the nurse, I’d bet they would do better because of their history of MSK development.
    So, we can take sides and polarize the discussions with clever quips, or we can try to do the best for each person who happens to be a runner (or other). My approach is to always find a way to make and keep a person active, especially in the activity they love. I am watching the studies on both sides, and I am learning a lot, and I am being progressive with my advice.
    I always like to keep the old adage in mind: « When you’re holding a hammer, everything looks like a nail. » All practitioners are in danger of practicing this way, whether one is holding a scalpel, syringe, pill, shoe, orthotic, or promoting minimalist/bare foot. We all have our favourite « tools » and we need to be willing to go outside of our comfort zone and consider the other tools. If our livlihood is reliant on any one of these tools, then we need to re-evaluate our toolbox and perhaps fill it with more options, or refer to another professional who uses other tools. We cannot do this if we continue the « We vs They » discussions.
    Keep the knowledge flowing and the discussions going guys…it’s good for us all.

      Nice comment,
      I can just be agree with you. I think also that there is a lot too much ‘medical interventions’ (hammer) in 2012. Minimalism for me it’s the opposite. I love the definition of Mark Cucuzzella : The least amount of shoes you can safely wear now!

        I think this whole « debate » is a crock. It makes about as much sense as arguing that peolpe with poor eyesight shouldn’t wear glasses or contacts or that peolpe with any other natural abnormaility or « defect » should ignore it and it will automatically cure itself. Quite simply, there are runners who NEED support of some sort or they will not be able to run. By the same token, there are runners who MUST have orthotics, due to their natural, biomechanical idiosyncracies. If you are physically perfect and can run barefoot – great! If you can get buy with « minimalist shoes » great! But most runners are not biomechanically perfect so really good shoes and/or orthotics are a godsend. Quit making these runners like they are missing the boat by not jumping on the latest and trendiest bandwagon. This particular trend has the potential to do far more harm than good. Different strokes for different folks.

          Hello Yosmaira,
          We agree about what you say: Some runners do need some support… but a very very few percentage of all runners this is.
          We want to get runners to stop relying on shoes to run securely and start relying on themselves, to start strenghten their feet and run more naturally than what the big traditional shoes bring you to.
          Try one time to take your shoes off and run on a clean hard surface for a few dozen meters. The foot stride you’ll get from doing this is how you should run. You don’t need to be biomechanically perfect, you just need to protect yourself, not let the shoe do it.

          But the main thing is to keep running, whatever shoes you wear. That’s should be the main goal for all of us passionates,
          Best regards, :)

    Hey Blaise how goes the cause? The primary benefit to this intelligent discussion continues, it makes all of is who manage ourselves and or persons in pain and/or not in pain, better at what we do. Polarized discussion and even worse polarized management can have really lousy outcome. As a Physiotherapist in Canada who is spending a great deal of his time on this stuff, you should be encouraging your peer( other physiotherapists in Canada) to stand at ease at the gates of physical management and to seek out other lower limb expert/competent opinion. We hold on too tight to what we think we are certain of, the worse we get at what we do. This discussion should be about keeping questions alive not about redefining/defining truths and then holding on to them for all we are worth….not to get too philosophical with us pain management folks.

    I am not a fan of the revivalist minimal approach where show stores are sending people (runners or not) out the door with 5 fingers or other no cushion shoes, because this does cause many injuries and many lost goals and much frustration. I see it as a coach who often ends up with these people after they are injured from lack training to use these « shoes ». However the use of basic shoes like were sold in the 70s/80s makes sense; there is still cushioning, still protection from sharp objectives and still some amount of angle heel to toe. These type of shoes like Brooks Flow for example will allow comfortable and safe running without increased risk of injury. It is also clear that all current world records in distance or middle distance events have been run in spikes with a zero or very low heel to toe drop. Just dont push people into barefoot too quickly or too often. From a scientific or research perspective that may be obvious, but shoes are to be sold and people will by the trends. Maybe a « government » health warning should be given with each pair and training advice also.

      Hello there,
      Why would we need a government warning to a product that is status quo, natural, primary like??? I suggest we put that government warning to traditional shoes that are said to protect you from injuries without proper scientific evidence. Why do people get injured wearing minimalist shoes: one big reason could be because traditional shoes have weaken our body to run naturally.
      Agreed on the 70′s/80′s shoes. Those were much better than our modern « tanks ».

      …And in the end, whatever you run with, it’s all about wanting people to run! This is the goal!

      Have a good day !

    I just watched Kevin Kirby’s conference « Barefoot vs Shod Running : which is best? » which is sold directly by Coaches Choice DVD.
    Here are my on-the-spot impressions.

    The cost of 40$ plus shipping is rather for the content than for the quality of the making of the DVD!

    The DVD is divided in 3 parts.
    * First part exposes a whole set of theories surrounding footwear/barefoot (advantages, disadvantages, history, performance, biomechanical effects, …). Kevin is clear, science is well introduced and the content well sustained even though sometimes it stands on superficiality. Even by being a modern shoes advocate, Kevin’s speech is so well balanced that I almost agree with everything he says… I’m questioning myself if he wouldn’t be discreetly becoming a defender of minimalism… :)
    * Second part was about the 5 most frequent pathologies in runners. For this one section, it all comes back to the 80′s, exposed ideas are backward and not so interesting. We see many ridiculous proposition like orthotics and anti-inflammatory to treat almost every problem, Q angle as the cause of patellofemoral syndrome, pronation as cause of the Achilles tendinitis, VMO strengthening exercises to treat patellofemoral syndrome… well, many outdated and uninteresting concepts.
    * Third part, the question and answer period had a lack of interest too. I did smile when the very first question was asked with three words: Big Bulky Shoes. However, Kevin, a little political in his answers, did well. We can’t say he doesn’t know literature

    Conclusion: interesting only if the footwear/barefoot debate fascinates you!

    Je viens de visualiser la conférence de Kevin Kirby « Barefoot vs Shod Running : which is best? » qui est vendu directement par Coaches Choice DVD.
    Voici mes impressions à chaud :

    Le coût de 40$ US plus shipping n’est pas pour la qualité de la conferction du DVD (visuel et technique un peu baclés) mais bien pour le contenu!

    Le DVD est divisé en 3 parties.
    * La première partie expose l’ensemble des théories autour de la chaussure/pieds nus (avantages, inconvénients, histoire, performance, effet biomécanique, …). Kevin est clair, la science est bien amenée et le contenu bien soutenu même si on reste un peu dans la superficialité parfois. Même en étant un défenseur de la chaussure moderne, le discours de Kevin est tellement bien dosé que je suis presque d’accord avec tout ce qu’il avance… je me questionne s’il n’est pas en train de devenir discrètement un défenseur du minimalisme… :)
    * La deuxième partie traitait des 5 pathologies les plus fréquentes chez le coureur. Pour cette section-là, on revient aux années 80 et les idées exposées sont arrièrées et très peu intéressantes. On verra plusieurs
    propositions ridicules comme l’orthèse plantaire et les anti-inflammatoires pour traiter presque tous les problèmes, l’angle Q comme cause des SFP, la pronation comme cause de la tendinite d’Achille, le renforcement du VMO pour traiter les SFP… bref, plusieurs concepts dépassés et sans interêt.
    * La troisième partie, la période de questions est sans grand intérêt non plus. j’ai quand même souri lorsque la toute première question était composé de ces 3 mots : Big Bulky Shoes. Kevin, un peu politique dans ses réponses, a tout de même bien fait. On ne peut pas lui reprocher de ne pas connaître la littérature.

    Conclusion : intéressant seulement si le débat chaussure – pied nu vous passionne!

    Keep up the good work Blaise!
    Keep exposing and calling out the dinosaur’s with lightly veiled agendas…
    BTW racing flats of old (I used to run in them ) might of had less padding/support but they still had toe spring and excessive taper!
