Dan Lieberman on Running Form
Harvard's Daniel Lieberman is one of the stars in Chris McDougall's book, Born To Run. In the book, Chris describes Dr. Lieberman's anthropological theory that humans ability to run long distances (while maintaining their body temperature) allowed us to chase down animals that, for short distances, are much faster than we are. He also details Lieberman's research into running mechanics and running form, including the famous study that demonstrated how barefoot running puts less force through your joints and can be better/safer for you.Well, thanks to Pete Larson at www.runblogger.com (who turned me onto the following video), and thanks to Tuck at http://yelling-stop.blogspot.com/ (from whom Pete found it), I'm happy to share this video of Dan sharing his top 5 tips for better running.All I would add (and I'm about to release something that describes this) is that "Don't overdo it" isn't a useful message, because the only way you know if you've over-done it, is when you've done too much and it's over! ;-)In other words, better to come up with a plan for what you ARE going to do, rather than make an admonition about what you shouldn't do, since us humans are as bad at following "don't do this" rules as we may be as good at chasing down an antelope.
See, Barefoot Running is NOT Bad for You
The media is an interesting thing. One day, they love you, the next day they hate you. As long as there's controversy, they're interested... ish. The last time barefoot running made all the news it was when the University of Colorado study (done right up the hill from me) apparently showed that barefoot running was less efficient than running in shoes (see my analysis of that study here). In fact, when that study got published, the media went crazy, practically insisting that this was the death knell for those of us who run unshod. So, I'm not sure what it means that they've basically ignored a new study from Northumbria University that shows the exact opposite! Why are there no crazed headlines about how running without shoes really IS the greatest thing since bread, the slicer, and the sliced bread that comes from intelligently combining the two? Who knows. Who cares. More importantly, check out the info about the study here at ScienceDaily.com In short, if you want the synopsis: Runners used 6% more energy when they wore shoes. Here's the line I like: The results suggest that, by ditching their trainers, athletes new to barefoot running adopt a running style similar to experienced barefoot runners and enjoy an immediate and likely beneficial increase in running economy. Works for me (in fact it DID work for me!)
Vibrating insoles, bare feet, and balance
The Wall Street Journal online published an article describing the research of James Collins from Harvard. James wondered why people get less steady on their feet as they get older.His conclusion: They get less feedback from the ground and lose the ability to balance.So far so good.His solution: An insole that provides random vibration to stimulate the nerves in the feet.Can anyone here think of another way of doing the same thing, but without all the electronic bells and whistles? Anyone? Beuler? Beuler?If you said, "Take off your shoes!" you win any prize on the second row!If you said "Take off your shoes! And if you don't want to step on unpleasant things, wear Xero Shoes!" you get a prize from the TOP row! ;-)If you think about this, it sheds light on another bit of research on balance and the elderly: Studies have shown that Tai Chi can help elderly people regain their balance. But it's probably not the Tai Chi that's causing the effect (BTW, I have nothing against Tai Chi... I did it and taught it for years). It's the time spent barefoot, FEELING the ground.I hope that someone does a study with Xero Shoes and balance sometime. I'd place a bet on the outcome.The content of this post does not constitute and is not intended to be a substitute for professional medical advice, diagnosis or treatment.

Barefoot Running... The Movie!
I know many of you are eagerly waiting for the Born To Run movie (I am, too).Well, until that's out at your local gajillion-plex, check out this trailer of the new barefoot running movie by Michael Sandler and Jessie Lee, authors of Barefoot Running.I'm forever grateful to Michael and Jessie... when I decided to try running barefoot as a way to deal with my persistent running injuries, I was fortunate enough that they were teaching a workshop that very weekend, right in my backyard (metaphorically speaking... it was 3 miles away).Even more, after my first barefoot run, when I said to Michael, "Well, that was interesting, but I'm a sprinter, not a long, slow distance guy," he encouraged me to try it a few more times and, for some reason, I did.Then, Jessie, being a former sprinter herself, added a whole other level of fun when we would take off across some field, leaving the LSD runners in the dust ;-)Oh, and it was Michael saying, "If you had a website for these sandals you're making, I'd put you in our new book," that was the beginning of Xero Shoes!If you watch this trailer and don't want to book a ticket for the workshop where Michael and Jessie take you to all of these amazing locations, then there's something wrong with you (or you already live in Hawaii).I've seen clips from the entire movie and it's really something special. Enjoy.
How to think like a shoe company
You know the saying "when all you have is a hammer, everything looks like a nail"?Well, it's true for shoe companies, too. When all you have is padding and motion-control, everything looks like it pronates and lands too hard!Check out this video about the "secret" Adidas development center. Especially watch at the 2:10 mark where the "best people in the world" analyze Ben's sprinting gait and conclude:a) That he pronates and heel-strikes (NOTE: He over pronates BECAUSE he heel-strikes since, when you land on your heel, the ankle muscles can't can hold the foot/ankle/lower leg in place).b) The solution: Making a shoe with padding and motion control!Uh...First of all, if you heel strike when you sprint, you are not sprinting! Sprinters do not heel strike. And when you land on your forefoot or midfoot, the entire musculature of the lower leg, ankle, and foot, can be "pre-loaded" and engage when you land.The cure for Ben is to STOP HEEL STRIKING, not get a shoe that lets him continue to run incorrectly. Duh.My next comment falls into the "maybe it's just me" category: Notice how large, spacious and expensive this place is. Ben mentions that Adidas does over a BILLION euros in sales.Look, I'm the last guy to deny any company the right to make money, and I'd love to have a billion dollar company.But am I the only one who sees a direct connection between a massive, pricey research lab and shoes that cost $150-200, and "hi-tech" shirts that cost $100+. This is like a thought I had at the Outdoor Retailer trade show, where some of the bigger companies have booths that easily cost over $1,000,000, "Oh, now I know why they charge so much for their products! They need to support the booth."Honestly, I find it unlikely that the "amazing" research they're doing actually pays for itself. I think it makes them feel good about themselves, and makes naive reporters think, "Oh, wow, they're doing something really special here."I don't doubt for a second that they could drop the price of their shoes to something more reasonable, not waste money on "research" that's iffy at best, and still make the same profit.Again, maybe that's just me.The content of this post does not constitute and is not intended to be a substitute for professional medical advice, diagnosis or treatment.

Run in Peace, Micah True
There's no way to adequately thank one of the great inspirations in the running world, Micah True, also known as Caballo Blanco ("White Horse"), who was found dead just hours ago. Micah, arguably the "star" of Christopher McDougall's best seller, Born To Run, went out for a run on Tuesday and did not return. There's no news at this moment about a cause of death.As Micah would often say in signing off, "Run Free!"Run In Peace, Micah.
University of Colorado Barefoot Running Study
The media is having an anti-barefoot running field day thanks to a study published by some people right up the street from me at the University of Colorado (BTW, I've been living in Boulder for 19 years and nobody has been able to explain why they call the university CU instead of UC.).Each of the dozens of articles about the study has a distinct flavor of elementary school playground taunting, "Nah, nah, nah, nah, boo, boo… barefoot running isn't good for you!"I mean, check out some of the headlines: Debunking the Barefoot Running Myth - Sydney Morning Herald (barefoot running isn't like bigfoot!) Here's Proof Barefoot Isn't Better -- Running Times (Ha! So there!)It almost feels like the press is enjoying creating a backlash to all the "pro" barefoot articles of the last two years, even though in every barefoot article I've read the media insists on publishing "both sides of the story," and includes some doctor who's never run a meter in bare feet and wouldn't know decent barefoot running form if it ran him over, claiming that running without shoes will hurt you, bring shame on your family, and accelerate the coming apocalypse.So, let's take a deep belly breath or two and have a chat about the study. In fact, let's start by talking about studies, in general:Designing a biomechanics study is not easy. Aside from deciding exactly what you want to explore and the best design of the study itself (how you can test it), finding enough of the right kind of participants is often tricky, if not impossible.It's even more difficult to design a study that isn't artificial in some way. That is, it's showing effects in a lab that may not be relevant in the real world.And, even more, many studies, while interesting, may not be relevant to the broader population. (Whenever someone quotes a study, or even just the habits, of elite marathoners, I respond "Unless you're 5'5" and weigh 105 pounds and run at 13 miles per hour for two hours... WHO CARES what those guys do?)Finally, the way the media picks up a study -- this one or any of the previous barefoot studies -- often adds some spin that isn't in the actual study.All of the issues I just raised are relevant as we take a gander at the CU study. BTW, if you want to see a lively and cogent critical look at the study, you can't go wrong with reading the comments on the New York Times article about it. Frankly, this post probably won't be as lucid as some of the comments there.Okay, let's jump into it… The gist of the study:"In the study, 12 subjects with substantial barefoot running experience ran at 7.5 MPH with a mid-foot strike pattern on a motorized treadmill, both barefoot and in lightweight cushioned shoes (~150 g/shoe, 5.4 oz). In additional trials, they attached small lead strips to each foot/shoe (~150, ~300, ~450 g). For each condition, they measured the subjects’ rates of oxygen consumption and carbon dioxide production as an index of metabolic cost.”And the results:a) For every 100g (3.5oz) (the average weight of a deck of playing cards) added per foot, energy cost increases by approximately 1% whether running barefoot or shod.b) Running barefoot and in lightweight shoes do not significantly differ in energy cost.c) When controlling for shoe/foot mass, running in lightweight shoes requires ~3-4% less energy than running barefoot."Now, let the fun begin. Can you find the "confounds" (the factors in the study that might affect the results, or the interpretation of the results)?I'll start. Let me know if you find more.1) How did they determine that the 12 subjects had "substantial barefoot experience?" Well, the study says, “8 km/week barefoot or in minimal running footwear (e.g. Vibram Five Fingers) for at least 3 months out of the last year.”Does 3 months out of the last 12 really equal "substantial?" I've been barefoot for 3 years, and I'm STILL improving my form.And if that three months was wearing VFFs or minimalist shoes, that counts as "barefoot experience" Uh…As I've commented, and as the American Council on Exercise showed, and as Pete Larsen from www.runblogger.com captured on video: VFFs are not the same as barefoot.Now the researchers did verify that the subjects all ran with a "midfoot or forefoot" landing. I know that Lee Saxby, the spokesman and coach from Vivobarefoot would have an issue with that. He doesn't think midfoot is proper barefoot form (there's some debate about that, but it's besides the point at the moment).2) They ran on a treadmill. Look, I get that testing runners on an actual track is hard and expensive, but running on a treadmill is not the same as running on the ground, end of story. It may give some useful data, but if it walks like a duck and quacks like a duck, but the duck is on a treadmill… hmmm, that analogy isn't quite working, but you know what I mean.I did some high-speed video analysis of my running at the Monfort Human Performance Lab. I hit 21 mph on that treadmill. I can tell you that when I'm on a treadmill, my stride is different than on the track. I overstride so I can "catch" the treadmill belt, for example.3) To simulate a running shoe's weight, the researchers put lead weights on the top surface of the runners' feet. Do you think some small weights pressing down on your foot is different than having that same amount of weight distributed evenly, and mostly under your foot, thanks to the design of the shoe? I do. Does that matter? Could be. Is there a way to check… not easily.4) The runners were at 7.5 miles per hour. That's slow for an elite runner -- about 200 meters in a minute, a quarter mile in 2 minutes, a mile in 8 minutes -- but fast for most casual runners. This raises a few questions:a) How was that pace compared to the runners' usual training pace? b) Does speed make a difference? c) What about turnover, or cadence? Were those controlled and the same when the runners were barefoot vs. shod?Got me. But, suffice it to say, we're seeing the artificial quality of the study.5) Oh, this wasn't mentioned above, but I'll give it to you now: the runners were wearing yoga socks. "“For the duration of the experiment, subjects wore very thin, slip-resistant yoga socks for safety and hygienic purposes.”Hygienic purposes? Uh, some 409 and a paper towel would handle any "hygiene issues." And "safety"? If you read the study, one aspect of "safety" is "avoiding blisters."Boy, where to start on that one? We know that socks does not equal barefoot, and we also know that if you get blisters when you run barefoot, you're doing something wrong. So, this brings us back to number 1 -- how experienced were these runners really?6) The study measured oxygen consumption and carbon dioxide production. Okay, that's a fine way to measure efficiency, based on the idea that using less oxygen and producing less CO2 means you're using less effort, and that equals being more efficient.But here's a question: So what?For one: does using less energy equate to faster times? It seems like it might, but that's not a given.Does the amount of extra energy being used by *some* of the barefoot runners have any relevance to the average runner? Someone for whom 7.5 mph is too fast… or even too slow?7) Oh, here's a favorite. The runners in the study wore an ultra-lighweight racing flat. Most runners wouldn't wear those. And most runners with no barefoot experience wouldn't find those any friendlier than being shoe-free.8) One other thing: A hallmark of the scientific method is reproducibility. Just because one lab gets a result, that doesn't mean the question is resolved. When a study is reproduced in independent labs and the same (or very similar) result is obtained... then you know you've got something.What if the study is correct, though? What if barefoot running is less efficient than shod running?The only answer I can come up with is: Who cares?I don't mean that it's not important to know. I mean, literally, who should care?If you never race, you'll never notice any difference in efficiency (assuming, again that "decreased efficiency" = slower times).Besides, there are MANY other reasons to run with bare feet than the idea that it's more efficient... many that have barely been touched on (Dr. Michael Merzenich and I have had some interesting chats about how being barefoot could help the elderly in various ways). Personally, I didn't make the switch for efficiency's sake. In fact, for me, as a sprinter, I know I'm more effective in spikes than barefoot. I switched because it helped me correct some form problems, eliminated injuries I was getting, turned running from a chore into an enthralling discovery, and, more importantly... WAS FUN.Don't get me wrong, I'm thrilled that my Boulder neighbors are researching barefoot running. And while this is the first published study, I know they have more coming and I'm looking forward to those.And I'm certainly not blaming them for how the media is handling the story.My only interest is the continued exploration, conversation, and understanding of efficient movement, running for speed and/or distance, and the ways of teaching and exploring barefoot running (and walking and hiking).No one study can perfectly address all of the open questions. But the almost combative attitude where everyone wants to jump on some one-sided "We're better!" bandwagon certainly doesn't help.Suffice it to say, this study is not the death knell of barefoot running that many media outlets are portraying it to be (because, you know, controversy is more important than truth if you're trying to sell papers).Now, if you'll pardon me, I have to burn off some of my frustration by putting on some yoga socks and minimalist shoes and going for a barefoot run.p.s. (added on 4/4/2012):I just realized that the conclusion of the study was WAY off base!Here's whyThe researchers think that the improved efficiency of the shoes came from the PADDING absorbing some of the stress that the muscles have to handle when you're barefoot.In other words, the ENTIRE efficiency effect could be ALL about the padding and have nothing to do with weight. The weight issue would only be valid if they tested multiple shoes of the same weight with different types of padded outsoles and got the same results.The content of this post does not constitute and is not intended to be a substitute for professional medical advice, diagnosis or treatment.

Dr. Mark's brilliant Natural Running video
Dr. Mark Cucuzzella is not only FAST (he won the US Air Force Marathon this year), he's committed to understanding the facts of barefoot running (and minimalist, too).As a physician, professor, and owner of Two Rivers Treads running shoe store, Mark is all about getting people running safely, enjoyably, and easily. Plus, he's a really nice guy.Mark just released an incredible video about "Natural Running." His emphasis in the video is about running barefoot, but his point is that if you run with a natural gait, you may be fine in a minimialist running shoe, too.Check out this video and let me know what you think.One of my favorite parts is simply seeing mark run... FAST. There are so many critics who say "You never see barefoot runners who have any speed" (forgetting, of course, Abebe Bikila, Zola Budd, Ron Hill, and many other fast, barefoot Olympians).I also like how Mark doesn't emphasize exactly how your foot is supposed to hit the ground other than "don't heel strike." A number of us, including Mark and Pete Larson (of www.runblogger.com) have been saying, "There will be individual differences in how you land on your foot -- from flat-footed, to fore-foot -- that will depend on your physiology and biomechanics as well as how fast you're running and whether you're running uphill, downhill, and even on the surface."That said, most new runners may want to focus on a forefoot strike at first, if for no other reason than many of us have lost our proprioceptive skills from years of wearing shoes and may think we're mid- or fore-foot landing when we're still heel striking. I've had more than my share of runners try to convince me that their heels never touched the ground, even when looking at video showing them clearly heel striking.Thanks to Mark for this great addition to the world of barefoot and natural running.The content of this post does not constitute and is not intended to be a substitute for professional medical advice, diagnosis or treatment.

Barefoot in Asia - Regev's Review
I just realized that I have a strange history with barefoot running, barefoot walking, and minimalist shoes.First, like most of us, I spent a lot of time barefoot as a kid in the Summer. I went to a camp in the Pocono Mountains (Camp Shohola just in case any readers also went there) and whenever I had the chance, I was barefoot (made easier by the fact that I spent half of my days doing water sports). I was a competitive diver, too, so that kept me out of shoes.In junior high school and high school, I was a gymnast, so that was even more barefoot time every day.When I was 18, I went to New York City to be a street performer. I had already been doing this in Washington, DC, doing a magic act in Georgetown, and on K Street, near the White House. When I got to NYC, though, I found it much harder to get a crowd and, even worse, within a few weeks, the other street magicians had stolen all my bits! I asked one of the veteran street acts what I should do and he said, "Simple, write an act that nobody would dare steal."I pondered this for a while, until I landed on the answer. I created an act that had a bunch of crazy gymnastics in it (I did a running front flip over someone's head, stealing their hat and placing it on my head while in mid-flip), and a finale where I... wait for it... walked on broken glass in my bare feet.Now let me back up. For the gymnastics part of the act, I wore minimalist shoes. They were some old Adidas (I can't remember the name), with zero-drop, very little toe spring, not much padding. Just enough between me and the ground so I didn't kill my feet. This was in 1980-81, BTW.I loved these shoes. I bought every pair I could find. When I could no longer find them, I asked the local running shoe store what happened and he answered, "Adidas stopped selling them; they were lasting too long."I don't know if his info was accurate but, if it was, it wouldn't be the first time a company pulled a product that didn't wear out or go obsolete fast enough.Luckily, I found a company that sold shoes to prisons (you can find ANYTHING in NYC), and they had the last few pairs of these shoes... I bought them all. And they lasted through some serious abuse.Okay, back to walking barefoot on glass, though. Let's just say that it's part physics, part showmanship, and part some-hard-to-describe-thing that, if I could convince you to jump onto a 3" high pile of shattered beer bottles, you would instantly get a knowing look in your eye and say, "Ahhh... I get it now."In 5 years and thousands of shows, I only got one small cut. But by the end of the day, my feet were FILTHY from being barefoot on the street.CUT TO: Going to Asia in 1989.This is where I got hooked on being barefoot. Aside from the fact that you never wear shoes into almost any building (I was in China, Nepal, India and Thailand), there were plenty of opportunities to be barefoot outside as well. There were also plenty of times where you wanted something on your feet, but not much because it was really hot when I was there, and anything more than a sandal was way too much.When I came back from Asia, I stuck with the habit of removing my shoes whenever I went into someone's home (we've saved a fortune on carpet cleaning by not dragging dirt in from the outside).Okay, so why this long story?Simple, I was reminded of it all when Regev Elya did his review of Xero Shoes, which he took on a 7-month trip through Southeast Asia (I'm SO jealous).Of course, I think that Xero Shoes are the best minimalist shoes for a trip like that... but check out what Regev says.
