		<description>@Jay - Please re-read my post.  The reference to &quot;snake oil&quot; follows the phrase &quot;Granting MacDougall&#039;s thesis...&quot;  My point is only that IF running shoes are snake oil, as he claims, THEN it illustrates an interesting economic point, namely that purchases of snake oil (of whatever kind, and surely there are uncontroversial examples) are counted positively in a widely-used measure of total welfare, while contributing nothing or perhaps even detracting from actual welfare.  Barefoot running remains an experiment for me, and I recognize that the jury is still out.  My use of a counterfactual to illustrate a point was not intended to be disrespectful to people who choose not to participate in the experiment themselves.  I apologize if any misunderstanding caused you offense.</description>

		<description>Thanks for the reply, Ian. I&#039;m glad to hear that barefoot running has enhanced your enjoyment of a sport we both share a love of.

I too would love to see more research on the supposed virtues of barefoot running, and hope that indeed more work is done to research injury prevention - whatever the method.

I would ask again though that when presenting your love of barefoot running you refrain from denigrating those that have made a different choice. Doing so does nothing to strengthen your case, and in fact damages it considerably.</description>

		<description>@Jay - First, the Harvard study I linked to shows that, surfaces being equal, barefoot runners experience less impact than shod runners: &quot;Kinematic and kinetic analyses show that even on hard surfaces, barefoot runners who fore-foot strike generate smaller collision forces than shod rear-foot strikers.&quot;

Second, elite runners race in flats or track spikes with little or no padding.  Even so, as the NYT blog post suggests, they naturally or by training strike in the mid- and forefoot, i.e., precisely the gait that is naturally assumed by barefoot runners.  So to the extent they train in padded trainers, they don&#039;t disprove the fact that heel-striking in shoes generates more impact force than forefoot striking regardless of footwear. 

There is no research that supports the claim that padded trainers are injury preventing on any surface.  If there were any such benefits, it would be in the interests of shoe companies to demonstrate them.  The fact that they have not speaks volumes.

Finally, I would put to you the claim that the a millimeter or less of rubber or non-shock absorbing coated ballistic cloth makes a significant difference in the impact forces experienced by a runner wearing minimalist footwear.  In fact, my experience is that even minimalist footwear increases my tendency to get sloppy and heel-strike by virtue of the decreased sensitivity to irregularities in the running surface.  My legs and joints have never felt so fresh and unjarred following a long run as when I have run completely barefoot.  

But I understand that anecdote is not evidence.  I hope that the increased prevalence of barefoot running will generate the data to put relative injury rates to the test.  For my own part, I know I have never been injury-free running the same mileage on the same routes before I went barefoot/minimal.  If you feel the same way about padded trainers, then by all means log the miles in them.</description>

		<description>They wouldn&#039;t, but from everything I&#039;ve read about &quot;barefoot&quot; running, most &quot;barefoot&quot; runners log a considerable number, if not a majority, of their miles in some kind of moccasin or minimalist shoe.</description>

		<description>The &quot;shoe company conspiracy&quot; is an oft-quoted argument, but I&#039;m not buying it.

If, say, one of the Nike-sponsored elite runners went to Nike and said, &quot;I think I can reduce my injuries, train harder, win medals, and set records if you&#039;d design me a minimalist running sandal .. and when I do you&#039;ll make millions selling these cheaper to manufacture sandals at huge markups&quot;, Nike would do this so fast it would boggle the mind.

That this is not happening, and there are no elite runners running in no/minimal footwear and winning major races and breaking records speaks more loudly than any clinical trial ever could.</description>

		<description>I can imagine a clinical trial to address this question. Shoe companies would fund it if they could control the results, and you know what those would be in that case. But who would fund a less obviously conflicted one?</description>

		<description>To clarify, my comment about a &quot;devoid of science&quot; is not in regards to barefoot running in general ... just the notion that barefoot running somehow negates the incredibly damaging effects of running on concrete as opposed to other surfaces.</description>

		<description>Like McDougal&#039;s book, an interesting article and video... but devoid of any science to back up the fact that running on concrete is &quot;like cream&quot; (asphalt by the way is a fine choice for running - barefoot or otherwise -  as it is up to 10x softer than concrete). The Tarahumara don&#039;t run on concrete.

One missed opportunity in the interview was when they saw the &quot;men&#039;s pro race&quot;.

&quot;After a mile or so we peeled off the loop and caught the men’s pro race at the Fifth Avenue Mile. As the leaders blazed by us, Christopher admired their form. “Look at how lightly they land,” he said, “even at that speed.”

The author missed a great opportunity to ask Mr. McDougal ... &quot;why are none of those pros running barefoot? Or at least with minimalist moccasins?&quot;

The barefoot running movement would do a better job of advancing their cause if they convinced some world class runners to train, race, win medals, and break records barefoot or in minimalist moccasins ... and if didn&#039;t coat every article on their cause with haughty suggestions that shoe wearers are mindless sheep wasting their money on &quot;snake oil&quot;.</description>

		<description>Concrete probably is the worst surface you can run on, if you happen to be wearing running shoes.  But the hardness of he surface is a matter of near indifference when you are barefoot, because you are not heel striking.  Impact is just not an issue.  That&#039;s why I am able to run 80% of my mileage barefoot on concrete and asphalt without injury or discomfort.  
Don&#039;t believe me?  Check out this NY Times video and blog post about &quot;Born to Run&quot; author Christopher McDougall, who says: “The hard, man-made surfaces are like cream.”
