today i ran two miles completely barefoot. not "barefoot" with my vibram fivefingers, but completely unshod.
a coworker sent me this webpage after i mentioned i ran barefoot:
http://well.blogs.nytimes.com/2009/10/21/phys-ed-is-running-barefoot-better-for-you/?em
here's the short version, quoted from that article, on why i'm running unshod:
"On the one hand, no one has yet published a study on whether barefoot running is better for you -- the evidence is all anecdotal," Lieberman says. "On the other hand, no one has ever published a study showing that running shoes prevent injury."
in my case, running shoes have always been a problem. i had a pair that i liked, once, years ago, and then they were discontinued to generate more profits for the shoe company. these were top-shelf, wildly popular shoes, too, and the revision was totally different. even the fivefingers irk me on a longer run, and they encourage bad behavior.
in the 5fs, i tend to run too high on my toes, or to flap my feet on teh pavement when i attempt to correct for toe running. barefoot, right out the door i noticed i was immediately in a much better foot posture. the tenderness of my toes instructed me straight off when my landing/takeoff was sloppy. the feedback from the road was incredible - as barefoot runners will tell you is always the case.
i was very surprised how much of the road feedback is actually masked by the 5fingers. true, the 5fs are far, far superior to "traditional" running shoes - they punish heel-strike almost as much barefooting - but they mask other bad habits, like toe-running, toe-scraping, and foot flapping. not only that, but they *do* have arch support, which i find conflicts with the natural expansion of my feet over a run. i have to stop and loosen them, or suffer.
in any case, i finished my run with absolutely no pain anyhwere but my toe pads. i expected my toe pads to be torn and bloody but they were intact, just a little irritated. i will work more on my landing/takeoff to avoid scraping them, but i won't be putting shoes on again for my runs.
i find arguments like this to be specious at best:
The debate about whether barefoot running is somehow better underestimates the main player in the whole argument. "The body is quite smart and adaptable," Nigg says. In complex biomechanics studies that he's undertaken recently in his laboratory, he's found that people's leg muscles adjust, rather smoothly, to changes in their footwear. If you run barefoot and land near the front of your foot, he says, the impact moves up your leg along a different pathway than if you wear shoes. But your body can sense that difference, he says, and, as a result, different muscles fire, while other relax -- without any conscious volition on your part -- and the overall impact on the leg's various tissues remains about the same.
That's certainly fine on a treadmill but a real outdoors run involves curbs, uneven surfaces, cambered surfaces, and rocks and pine cones. in shoes, these things always twist my ankle -- i've been fortunate never to have injured my ankle seriously. barefoot, i'm paying so much attention that i never come close to such obstructions.
i don't buy the "overall impact" argument, either. in my running shoes, i impacted far more heavily than i do in the 5fs or barefoot, because my technique is vastly different. again, this is less apparent on a cushy lab treadmill, or even outdoors, since technique changes gradually.
"The body learns very quickly to compensate," he says. So, Nigg concludes, if you like your shoes, "stick with them." If you want to try running barefoot, Ross Tucker says, be judicious. "Many years of wearing shoes condition the muscle, tendons, and skeleton and a sudden shift to barefoot running" could, at least in the short term, be painful, he says. Start by running barefoot perhaps once a week, he suggests.
i used to buy this line of crap, too. but i deadlift, cycle, and climb -- i don't have any weak muscles, tendons, or skeletons. i'm not ready to run a marathon barefoot (i do have weak, soft soles) but my limiter is definitely not weak tendons.
