The Barefoot Backlash: Are the Naysayers Right After All? (Hint: No.)

BarefootingEvery few days, I get emails from readers worried about the growing barefoot backlash. The media has gone from shooting out a positive article or two every couple months about this “crazy, quirky new fad” of barefoot running to spearheading the charge condemning the practice as dangerous and unAmerican. It’s like clockwork; when something becomes too well known and popular to justify glowing, exploratory write-ups that interest readers, you start attacking it, and the readers come flowing back. They see the results of a perfectly reasonable study fall into their newsfeed and the wheels begin to turn. “How can I interpret this research in such a way to maximize ire raised?” The press loves a good backlash, even (especially) if they have to manufacture it.

And so the headlines come in droves. And boy are they scary and ominous.

The scare tactics used in these articles will be familiar:

Quotes from podiatrists and physical therapists who are seeing a “rash of barefoot running-related injuries” in their clinics. I would certainly hope that podiatrists and physical therapists are seeing people with injuries. It’d be pretty strange if people without lower extremity injuries were going in to see the podiatrist just for the heck of it. Besides, how does their anecdotal evidence compare with the empirical evidence that 90% of people training for a marathon (the vast majority of whom are wearing shoes) will get injured?

Construction of strawmen, like this idea that barefoot or minimalist runners are all doing it for the “increased running economy” and “to run faster.” Who says that? People generally switch to barefoot running to avoid (or fix existing) injuries, improve proprioceptive awareness, and increase sensory enjoyment of running. There’s even evidence that running in Vibram Fivefingers (and, presumably, in other minimalist shoes or none at all) results in greater improvements to mood than running in standard shoes. Besides, now that they mention it, there actually is evidence that minimally-shod runners are more economical due to greater amounts of elastic energy storage and release in the lower leg.

References to the lack of elite runners going barefoot. Well, yeah. Going barefoot has never been about maximizing your performance or destroying the opposition. It’s not about emulating what the elite do, because, let’s face it, the elite are sacrificing health for the sake of performance. Shoes allow you to tune out the pain and push yourself past your body’s naturally-endowed limits. That’s fine if you’re getting paid (well) to do it, but if your training is extracurricular, it should be enjoyable and health-promoting.

As is often the case, the blame lies squarely in the laps of the “journalists” salivating over the prospect of a controversial story that will populate the comment section with angry parties from both sides and drum up hits to their article, not the scientists behind the research. They’re generally just trying to figure out what’s going on with the barefoot running thing, and their conclusions are very reasonable and measured. Let’s look at some of the most recent research into barefoot running to see what’s really going on:

Study #1: Economy and rate of carbohydrate oxidation during running with rearfoot and forefoot strike patterns.

What an anti-barefoot article might say about it: Rearfoot striking is more economical than forefoot striking.

What the study actually says: “No differences in Vo2 or %CHO were detected between groups when running with their habitual footstrike pattern.” Habitual forefoot runners and habitual rearfoot runners were equally economical. However, when forefoot runners tried heel-striking and heel-strikers tried forefoot running, the latter group were less economical than the former group. This shouldn’t surprise you. Forefoot running takes practice, especially if you’ve been heel-striking all your life. Most people end up on their tippy toes bouncing up and down rather than smoothly gliding forward on their first try; the up and down motion wastes a ton of forward momentum and is anything but economical.

Study #2: EMG and tibial shock upon the first attempt at barefoot running.

What an anti-barefoot article might say about it: Barefoot running has “detrimental effects on the runner,” increasing strain on the calves and shocking the shins.

What the study actually says: Barefoot style running may be “ultimately less injurious,” but it poses an initially greater shock to the lower extremities that must be accounted for. Habitually shod runners who heel strike should “undertake the process cautiously” before switching to barefoot running.

Study #3: Minimalist shoe injuries: Three case reports

What an anti-barefoot article might say about it: Running in minimalist shoes has been shown to increase injury rates.

What the study actually says: “All three of the runners switched immediately to the minimalist shoes with no transition period. We recommend that any transition to minimalist shoe gear be performed gradually.”

So, is going barefoot totally safe? Do we really have nothing to worry about?

Well, no. I never said we did. No one said that. Nothing is inherently safe. It’s all in how you do it.

Barefooting is not a panacea. It doesn’t make you invulnerable to running injuries; it makes you more sensitive to their approach.

I’m not sure we’re even meant to run as much as some people like to do, whether barefoot or shod. As humans, we can distance run. As humans, we did distance run. But Grok wasn’t training for marathons. He wasn’t logging miles for the hell of it. The distance run evolved as a necessity, as a way to procure food: the persistence hunt. It was an intermittent event, an acute dose of endurance activity, not a chronic one repeated ad infinitum. Because of that, there’s a threshold – and it’s different for everyone – after which you’re going to incur injuries if you keep running. Being barefoot offers a good barometer for that threshold. When we’ve had too much barefoot running, we generally feel it in our feet. Our soles grow tender, the foot muscles themselves might get overworked and sore, and the surrounding and supporting musculature and connective tissue start to tire. That’s a feature, not a flaw! Our feet are telling us to lay off them, to take a break, and that if we don’t, we risk serious injury. Shoes sever that connection. They obscure the message and make us think we have more in the tank than we actually do.

You can’t just “go barefoot” and have perfect form. You have to work at it. Barefoot running and even walking are skills that must be learned, whether through expert instruction or careful exploration of one’s own experience.

I used to think that sticking someone in a pair of Vibrams or having them run barefoot on a beach would naturally and necessarily prevent heel striking. This is not always the case. As minimalist running has grown more popular, it’s become increasingly clear that some people are able to maintain their heel striking habits even while minimally shod. Heel striking in minimalist shoes or while barefoot is far more damaging than heel striking in padded shoes. The only advantage I see is that it’s such a jarring experience to slam your bare heel on the ground (seriously, try it: jump up an inch off the ground and land on your bare heels; you’ll feel the shockwaves up through your entire body) that you couldn’t keep it up long enough to do too much damage. Heel striking in padded shoes is tolerable, which allows the damage to accumulate inconspicuously. Similarly, boxers are more likely to develop brain damage than mixed martial artists, probably because the padding on boxing gloves allows fighters to take hundreds of blows to the head in a single bout. MMA fighters wearing smaller gloves with far less padding often end fights with a single blow. They’re actually better off because they take far fewer hits and fights are over far more quickly.

Barefooting is a big change for most people who’ve spent the bulk of their lives walking and running in shoes.

Barefooting feels natural for the majority of people, but just because it feels right doesn’t mean your feet and lower body musculature aren’t atrophied from years or decades of shoes. You have to make the barefoot transition slowly and deliberately or risk some of these injuries mentioned in the articles, especially if you’re planning on barefoot running, which places a considerably greater load on your body than walking.

Like the recent flurry of articles criticizing ancestral health and Primal living ended up lecturing us on things we’d already hashed out in the community years ago, much of the barefoot backlash involves breathless “experts” uncovering what we’ve already known for a long time.

What about you, folks? Have you experienced a barefoot backlash? If you’ve ever tried barefooting or wearing minimalist footwear, how did it work out for you? Stick with it?
