It will be on Kindle, copies just arrived at the publisher so they need to now make the kindle file. Should be available by the release date on June 1.

Thanks!

 Just barefoot run. Or go to invisibleshoe.com and make or buy a sandal.

 One photo does not proof make. But I get your point. Love to see the video.

But the vast majority do not heel strike. The study I lined calls it “less often, on the heel (rear-foot strike)” in contrast to shod runners who mostly heel strike.

My point is, can you get the data or chart that shows the comparison between BF runners and shod runners? BF forefooters and Shod Rear footers or shod anything runners? Does that chart exist? Comparing FF BFers with Heel Strike BFer’s isn’t terribly useful.

Good work on the article tho. It explains a lot of why there is a benefit to FF running.

Any news on whether your book will be available in e-format?

 I guess all the clicks worked.

The notion that barefoot runners don’t heel strike is an absolute myth. Have you read the study you linked? Even Lieberman had some Kenyans who had never before worn shoes who heel strike when barefoot. And my article says nothing about barefoot being “better,” it just points our that there are differences in loading patterns between barefoot forefoot strikers, barefoot heel strikers, and shod heel strikers.

I recorded slow motion video at the NYC Barefoot Run last Fall, and I can assure you that there were many people heel striking both barefoot and in minimal shoes. It’s not common to see barefoot heel strikers, but it does happen, and in numbers that might surprise you. Here are some examples: https://runblogger.com/2011…

To me, that’s like comparing the performance of horses with unicorns. Rear foot barefoot strikers don’t exist. The whole point of barefoot running is if you land on your heel once, that will be the LAST time you make that mistake. Barefoot running naturally makes you a forefoot/midfoot runner.

The comparison most runners would like to see in terms of ground force is: barefoot fore strikers versus shod rear strikers or even shod runners generally. (Born to Run and other places present studies on BF versus shod runners saying BF puts less stress.)

You barely discuss that question but you do make a good point that the impact loading wasn’t much different but rate or speed of the loading is much faster in heel strikers and you make the point that that could be contributing to injuries.

You note a 2012 study by Adam Daoud from Harvard XC runners that shows RF runners had “twice the rate of repetitive injuries than” those who front strike. Great stuff.

The stuff about a locked ankle when RF running versus FS running using the foot as a shock absorber was great stuff that I haven’t seen elsewhere.

Next time, how about a chart that shows barefoot force versus shod?
Here’s a great study:

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.

I know since I moved to sandal running only (http://www.invisibleshoe.com) all my repetitive injuries have gone away. Plantar Fasciitis, Patella Tendinitis, some hamstring/upper calf thing, ITB issues, all gone.
