    Kevin, what this "barefoot running thing" has done for the running community at large is to put a heightened interest in ultralight running shoes. With that interest, just about every major running shoe company expect Asics has been coming out with new lines of ultralight running shoes that didn't exist 3 or 4 yrs ago. These new shoes are using TODAY's technology and the running community at large is benefiting from them.

    In high school I ran in the Asics version of the racing flat you used as an example. The shoes produced today are not at all the same shoe, NOT EVEN CLOSE.

    Kevin, try out a pair of Nike LunaRacers. They only weigh 7 OZ or about 2/3rds the weight of your example, yet they are fully cushioned and fully supportive. There is no comparison.

    It is apparent you have a lot of knowledge of the running shoe industry in the 70's, I'm not so sure how that compares to your knowledge of the shoes being produced today.

    Dana
     
  3. Says who? Dana "the self-proclaimed running shoe expert"?? What exactly do you do for a living, Dana???

    I haven't seen anyone benefit so far. Maybe you could provide some evidence for that rather remarkable statement.
     
  4. Assuming you meant except rather than expect, why do you think Asics are the exception?

    In what way are they benefiting from them?

    "Fully cushioned and fully supportive", sure? How are we measuring "fully"?

    Simon, take a look at Asics' current product line as well as it's product line over the last 15 yrs. Innovation or new technology are terms that probably won't come to mind. Asics has not been a company that demonstrates being out in the forefront so I would not expect them to start now. More than likely, once Nike, Adidas and New Balance, fully establish their position in the minimal shoe market, Asics will come in a day late and a dollar short.

    Prior to 2006, the shoe companies generally had a couple of models of ultralight shoes targeted at the races of 5K to 10K and 1/2 marathon to marathon, that was it. With the "barefoot" running movement which I said in an earlier post is more about running in minimal shoes than it is running barefoot, has gotten the shoe companies attention. Now those same shoe companies are producing entire lines of ultralight shoes. The shoes are not targeted at a specific racing distance but for training and for racing. The huge increase in ultralight shoe models vary in weight, flexibility, durability, cushioning, support and so on. The running community now has an entire spectrum of shoes that vary across multiple properties to choose from. All of which weigh under 7 or 8 ounces.

    In the past, shoe companies differentiated by adding bells, whistles and weight to their shoes. The barefoot running movement has gotten their attention with respect to reducing their shoes instead of adding to them.

    The running community is benefiting from shoe companies offering a much expanded selection of ultralight shoes AND potentially a reverse in the trend of their existing models getting lighter rather than heavier with the introduction of subsequent versions. I attribute the change in thinking of the shoe companies and the reflection of that thinking in their product line attributable to the barefoot running movement.

    With respect to Kevin's 1970's example. The shoe companies are taking that shoe and using the materials of today. The result is a shoe that weighs less than the 1970's shoe, has more cushion and more support and the shoe fits better. Why wouldn't a runner benefit from that?

    When I spoke of the LunaRacer being fully cushioned and fully supportive, I was using fully as a comparative adjective to Kevin's 1970's example and a traditional running shoe today. To spell it out, the LunaRacer uses technology that makes it lighter than Kevin's example which virtually has no cushioning was poor fitting and had little support. In spite of it's lightness, the LunaRacer has cushioning and support that is comparable to a traditional training shoe.

    If you want to learn more, read about Nike's Lunarlite midsole technology and Flywire support technology.

  6. Been fully aware of Nike's luna range since their launch. I particularly didn't like the idea that by lacing the shoe into different sections of the upper it would improve pronation control. We did some testing on this, and it didn't.

    Kevin, I never said I was a shoe expert, apparently you must think I am. What I do for a living has nothing to do with how little you know about the current running shoe industry. I have the impression that you once knew about running shoes in the 1970's when you were running. You certainly haven't demonstrated that you know much about what has gone on in the running shoe industry over the last 15 yrs or so. What type of a job do I need to do to be able to pick up on that?

    You haven't seen any benefit because you do not know what is going on in the shoe industry today. You are also unable to make the connection between the barefoot running movement and the minimal shoe movement. I went through the bother to spell out the benefit in my response to Simon. If you still don't get it, then I don't think I can help you.

    I also wondered about pronation control. Since I don't have pathological problems with pronation, I can't say much about it. What are your thoughts about the weight and cushioning properties of the lunar lite foam? Also about the weight and supportive properties of the Flywire technology?

    Dana
     
  9. It's certainly light but I haven't done any materials testing to compare with others. Usually a reduction in weight is achieved via a decrease in density, decrease in density usually = decreased longevity. The fly wire idea is interesting, again it would be nice to do some comparative studies...
     
  10. Dana:

    You are neither a shoe expert, and I have never once thought you were a shoe expert. However, the way you continually judge the knowledge of others on this academic forum for foot health professionals, you act is if you are a shoe expert.

    Therefore, Dana, why don't you stop telling me what I am and stop telling me what I know since you don't have a clue of either. In addition, unless you can provide me some evidence that you have any expertise (i.e. lectures you have given, papers you have published) on the biomechanics of running shoe design and function, then as far as I'm concerned, your comments are meaniningless to me (and probably many of the other podiatrists on this forum) since we want to learn from someone other than a recreational runner that works for a computer company and thinks that he is an expert in running shoes.

    Great words of insight provided by the "Most Valuable Poster".

    Kevin, I am not judging knowledge, rather I'm taking issue with many of your statements. I simply believe you are in the habit of making unsupported, unsubstantiated, anecdotal comments to support your own opinions. For example, you first questioned minimalist running shoes as a new thing calling it a joke. I took objection to your comment and pointed out that your racing flat example from 1972 is completely different from the minimalist running shoes being produced today. I followed up with a simple example of why it is different. Your comment simply reflects your level of understanding of the current running shoe industry.

    You then claimed that the "barefoot running thing" has done nothing for the running community. I again took objection to your comment. Your comment again demonstrates your lack of connection with the running shoe industry and the products it is producing. If you where more in tune with the current running shoe industry, you would know how it is being impacted by the "barefoot running thing" and would not have made that uniformed comment.

    Now you are accusing me of acting as if I'm a shoe expert? I'm just trying to inform you of what is actually going on in the running shoe industry. You don't have to be an expert by any means, rather an informed consumer is all.

    I firmly believe my comments or comments from anyone else that contradicts your opinion is meaningless to you. My comments are not for your benefit but to others who may be reading your point view when I find it too opinionated and unsubstantiated for me to sit back and ignore.

    Just think about it, it's got to be pretty bad when a non medical professional and a non running shoe expert can refute comments from the almighty most valuable poster.

    I see that the following video has been cited before on the previous page but I think it does a pretty good job of summing up some of the logic used in this thread & the "Barefoot Running Debate" thread...



    Maybe what the running community needs is just one model of running shoe. Get rid of the vast variety of different models filling the shelves from various shoe companies, which potentially confuses the customer (& even the salesperson - or provides an environment for dubious sales pitches to get a brand/model sales commission); eliminate the structure categories such as "neutral", "support" ("guidance"), "control" & thus maybe eliminate the purpose categories such as "training", "racing", "trail" etc...

    I really don't think we need such a variety of running shoes (based on a few reasons i.e. biomechanical, environmental). However, I can see why shoe manufacturers have/like the concept (based on a few reasons i.e. market competition, financial).

    Just one basic model which serves to apply protection for the plantar surface of the feet; have a level (no rearfoot - forefoot pitch) but thinner sole/midsole - say about 10mm (1cm) thick (to aid in protection; a bit of cushioning; flexibility: aid in faster ground contact time & proprioceptive feedback) & comfortable upper with lacing system.

    That's it... however, with each shoe contains a couple of rearfoot wedges & even a couple of arch cookies (with different size/correction available) which can be easily changed/modified (with basic instruction manual for their general application within the shoe) for the customer to fiddle around with for themselves. These "inshoe additions" can subsequently be easily changed/removed over time. If the runner is too biomechanically inept, then to be fitted with appropriate custom made orthotics.

    Problems solved! I think :confused:

    As per above video...

  13. Had a local guy call today to make an appointment. Long story short he has a history of Achilles problems and a recent fusion of one of his 1st MTPJ's, but the really exciting thing is that he told me on the phone that has "made is own running shoes". He's coming to see me in a few weeks time. I honestly can't wait. Brilliant!!!!!!

    You look in good shape Kevin :)
     
  17. Here's the take-home message from the Vibram FiveFinger ad:

    you should run naked to be more natural with the only exception that you must wear $100.00 thin-soled shoes with five toe sleeves instead of being barefoot to run in order to have "stability, arch support, pronation control"......etc....:bang::craig::cool:

    Where is Chris McDougall when you need him to complain of the high cost of these "natural running shoes"......oh......I forgot.....he is being paid by Vibram to lecture around the country to promote running in the FiveFinger shoe......:butcher:
     
  18. Which reminds me, this guy came in at the end of last week. He'd basically been plagued with Achilles tendon problems over the years, been told to try pose running and forefoot striking :bang: and had eventually given up running. He'd started to come back to it and had used eccentric loading exercises which had helped. He'd tried barefoot running, but could only do that on soft, safe surfaces- golf courses etc. So had made himself a pair of shoes- basically a flat eva sole unit (10mm) with an upper made out of some kind of nylon type material fastening around the heel, no heel stiffeners etc. He was still getting Achilles problems, so tried his wife's prefabricated foot orthoses, which seemed to help the problem even more. He wanted me to make some orthotics for him..... I told him he'd probably get resolution of symptoms with a modified prefab.

    I asked why he'd made his own shoes and had he heard of vibram's- "yeah but they're ridiculously expensive" or something like that was his response. Well, when you're running big publicity campaigns, you've got to pay for it somehow ;)

    Have a successful trip Kevin and a safe journey home.
     
  19. Leaving for Zaragoza, Spain early tomorrow morning with my lovely wife. Our mutual friend, Dr. Javier Pascual Huerta will be my "guide-translator" while I'm there so I'll be sure to say Hi to him for you. We will also be taking a 5 day vacation to Sevilla. Then we take the train back to Madrid to hang out with Javier and his students for a couple of days. Last time I was in Spain was April 2004....will be good to be back in this lovely country again.

    There is even a chance of snow in Zaragoza on Saturday during the seminar......should be fun!

    I'll be sure to post up some photos of the trip.

    Ciao!

    The US Army have banned Vibram Five Fingers

    To provide a wee bit more information:

    Quoted from http://birthdayshoes.com/u-s-army-outlaws-vibram-five-fingers#feedbacks

    The sudden increase in the use of minimalist running shoes has prompted the United States Army Physical Fitness School (USAPFS ) to provide additional guidance as to the definition of “commercial running shoes” referenced in AR 670-1 paragraph 14-3, dated 03FEB2005. This interim guidance which is offered in accordance with AR 670-1, Paragraph 14-3 states that; “Commanders may authorize the wear of commercial running shoes with the PFU and IPFU. Commercial running shoes do not include mininalmist shoes, light weight track/road racing flats, racing spikes, toe shoes, or shoes that simulate barefoot running. Commanders and leaders at all levels will comply with AR 670-1, Paragraph 14-3.”

    This policy only affects TRADOC (Training & Doctrine Command) which is where all Soldiers attend basic training and officer basic courses. However, the tone of the policy indicates that an Army-wide policy is forthcoming banning ALL "minimalist" shoes.

    the commandant of the physical fitness school. He (a government civilian) stated that VFFs and other similar minimalist shoes may provide an "unfair advantage" in the testing. The physical fitness tests were designed with "normal" commercial running shoes, and these don't fall into that category.

    As a member of Vibram TesterTeam, I am sorry about this information. Metatarsal Stress Fraction is an emergency for me. I once climbing a mountian that is more than 1,500m with VFF. The shank muscle is hurt. The thinkness of metatersal part is 3mm, and the heel one is 5mm thick. The shock absorption should be considered again and again.:pigs:

    I do believe that the the VFF shoeware has its place in the running world, just as the use of orthotics do. The runner's mechanics I feel are what lend the runner to be susceptible to injury. These injuries are very similar to dancers. What dancers are at risk for 2nd MT stress fractures? In my experience instability in the 1st ray leads these dancers at risk. For those who have suffered a stress fracture, perhaps more attention needs to be paid to the risks factors for that particular patient.

    I did the Brooks River Run 8k at the weekend. Came across two runners using Vibrams. One was going so slow, even I could pass him and I chuckled to myself as the other one pulled out with a what looked to be some sort of foot injury.
     
  26. I went to REI (a large camping/backpacking/clothing chain store) here in Sacramento over the weekend and tried on a pair of Vibram FiveFinger shoes again to see if they had changed much since I tried out a pair last year. In talking to the saleslady there, she made the interesting comment that a full 50% of the Vibrams are returned back to the store for a refund since REI has a "full refund if not satisfied with product" policy. She said that no other shoe she sells has such a high return rate (and they have quite a variety of shoes, sandals and boots at REI).

    Very interesting!

    Well done - on your participation in the event that is. I too had a good chuckle to myself on visualizing the above scene :D ... then another scene entered my head where everyone in the above race was either wearing Vibram FF or running barefoot (except you). As the event unfolded, you were either passing runners or they were falling by the wayside due to some form of niggle/injury... where you then crossed the line in first place :D... one can only imagine what the victory speach would be like.


    If only the saleslady knew who she was revealing the information to.

    We have a similar store in the Sydney CBD. Been planning to go there & ask a few little questions myself. Their range is quite extensive, thus a good place to get a feel for the variety of minimalist shoes out there. Here is the link for the store... Adventure Megastore... prices over here are far dearer than in the U.S :mad: (despite the exchange rate being very good at the moment).
     
  28. Here are some more people who have developed metatarsal stress fractures by running in the Vibram FiveFinger shoe.

    Its time for a centrist position to rise in this debate.

    The bottomline is people can run in whatever they want, as long as they want. They can run into injury and even to the point of ignoring pain, swelling, redness and obvious signs of imminemt critical injury into stress fractures. They have been doing it since 200 B.C.

    There have been centuries of recorded metatarsal stress fractures, many due to Military Boots that were hard, heeled and "supported" known as March fractures.

    Most modern stress fractures appear in sport and training shoes with heels, supporting counters, antipronatory features and the type of "protection" that Dr. Kirby seems to intimate doesn't exist in minimalism and forefoot contact running style that prevents them. This is just unfounded and unproven.

    Stress fractires are due to overactivity,overuse, overtraining or over something else, in people without the discipline to heed the warnings the body has presented them with.

    They occur when a person's activity level causes tissue stress within the surgical neck (or base of the 5th met) of a metatarsal to go beyond the pain threshold causing clinical pain and concomittant symptoms which is then continued to be overused to the point of fracture, PERIOD.

    The exact factors are impossible to isolate, experimentally determine or predict, they never have been!

    Whether it occurs in running shoes, minimalistic shoes, vibram's or barefoot, it is the overtraining for that person, for that activity, to the point of tissue stress that engages its maximum bone tolerance to the point of fracture, with a blind eye to preexisting signs of passing the tissue stress clinical threshold.

    A person's choice of activity, foot gear, goals of training or any other personal decisions are not in the pervue of doctors in my opinion. It is our goal to guide and train people to perform their lifestyle choices, safely and through whatever injury they choose, until it becomes dangerous or disabling.

    I'm surprised Dr. Kirby's biases are not suggesting we all should carried to work and through lifes activities in open chain and swim for exercise in order to maintain fitness so as to totally eliminate stress fractures.

    Oh Wait, that would eliminate his personal opinion about lifestyle choices from having an ear for his anecdotal opinions and those of others (see the above quotes).

    Barefooting is an acceptable lifestyle that is being selected in small numbers by those with a passion for it. It has proportional success when introduced and trained appropriately and proportional injuries including stress fractures when practiced by groups of people.

    Most stress fractures occurring modern running and training shoes and not in vibrams or barefooted.

    There you have it, undeniable scientific and medical proof that running causes stress fractures. Too bad, right when I was just beginning to enjoy running.

    From now on I'm going to play it safe. I plan on spending all of my 'recreational' time in a chair limiting my activity to watching TV and posting on the Podiatry Arena while eating Cheetos and chicken wings.

    I thought the thread was about the claim by barefoot/minimalist runners that running barefoot or in minimalist shoes reduces the injury rate and this thread is just illustrating that its actually probably increasing the injury rate.
     
  38. Probably a better way of looking at it is that claim by barefoot/minimalist runners that running barefoot or in minimalist shoes reduces the injury rate and this thread is just illustrating that its actually changing the percentage of injuries seen in certain locations.

    will people still get injured running barefoot, minimalist shoe or traditional running shoes - yes

    will the location and magnitude of injury generally be the same or different in 3 different running conditions - should be different, while all injuries will occur what ever your running preference is, there will be more of the same type seen in certain conditions.

    ie Forefoot striking with neoprene shoes, greater bending moments of the Metatarsals greater chance of stress fracture of the metatarsal than rearfoot striking in traditional running shoes.

    hence why it can be argued that - Vibram FiveFingers Cause Metatarsal Stress Fractures

    So the title of this thread is:
    Vibram FiveFingers Cause Metatarsal Stress Fractures?

    what were you smoking when you wrote this post??????

    In addition, actually, probably sounds like the level I evidence you say I do not have and not just some dribble coming from the side of your moth that is worthless.
