News and events

It has been a while again since I've added any entries here, partly because I ran and trained more than I was writing about running, and partly because my other lives took precedence for a while.

Firstly, I am teaching a workshop called "From Distal To Proximal" for Pilates trainers at A Body Of Work Studios on Ruger St. in the Presidio in San Francisco on November 4 from 1-4. The workshop is all about understanding how the feet and the core interact. We will be having some fun with the equipment and will get to know our feet through manual work and anatomy. It should be a blast. Contact A Body Of Work to enroll. Here's the official page.

Secondly, here is a great article which pretty much ties up the hype around barefoot running vs. shod.

"The truth about barefoot running: It’s complicated" by Cary Groner

What he says is that people who wear shoes have certain kinds of injuries. Barefoot runners have others. Training is important. Don't overdo it. Many barefoot runners wear shoes when they run, too. Many runners who swear by their shoes take them off to train.

He talks to Dr. Daniel Lieberman, (known as The Barefoot Professor,) who, while not happy about the hype that has developed around barefoot running, stands by the opinion that soft-soled running shoes that raise the heel are still terrible for human bodies.

I'd agree. On one hand, I have seen more and more people in our neighborhood with decent looking midfoot form in running shoes, and very few people actually running without shoes at all or in very minimal shoes like the FiveFingers or sandals. On the other hand, I still haven't found a minimal shoe (other than the FiveFingers) that I can run in comfortably. That includes huaraches! On the last hand, assuming that I can have three or more hands for the purpose of this paragraph, I absolutely refuse to spend more than $100.00 on running shoes, and continue to feel that the running shoe industry is a series of snake-oil scams.

As for injuries, it is true that each form has its own related set of problems. While I do occasionally get a foot injury from running barefoot and minimal, when I wore shoes I had debilitating pain in my neck, back, hips, knees and ankles. I gladly traded the second for the first!

If I had not had pain from running shod, then the tradeoff might not have been quite as attractive. I have to train my feet and the rest of me about five days a week to stay strong enough to run in the city. Which leads me to the next point.

What about running on hard, man-made surfaces? Is it good for us or not? It's certainly easier when running shoeless. I've heard many times that in order to learn how to run barefoot that the smooth sidewalk or pavement is what you want to start on, but there is a case to be made that a large, heavy person who tends to have lower muscle tone would not want to expose their bones to hard pavement as an introductory surface. If you are slight and strong, though, it may be fine. I do notice that when I run on pavement that my feet tend to be more sore afterwards and need to recover for a longer time than when I hike a trail or run on the track. For the record, I am 5' tall and about 112 lbs.

Lieberman briefly talks about the idea of a hard, smooth surface being unnatural in some ways, and that the consistency of the surface encourages repetitive stress. That takes me back to where I started a while back in this blog - that we are an all-or-nothing culture that loves to generalize without simplifying. We are fascinated with being the fastest, or going the farthest, doing the same thing over and over until we achieve some goal that we don't even realize is completely arbitrary. We forget that exercise isn't simply the repetition of this movement with this amount of weight then another movement with that amount of weight. While we like to create artificially symmetrical, repetitive systems for training our bodies (and everything else, really,) that's not how our bodies work.

If you watch a child outdoors, they don't just run. They run, stop, pick a flower, sprint to a tree, climb it, hang out there for a while and chirp at a bird, then they might stand up, balance and leap to the ground where they will gleefully roll around in the wet mud for a while before getting up and doing something completely different.

Varying activities truly strengthens the body, builds range of motion and balance. Most of all, though, it's FUN! I have learned when running that if I start feeling bored, or that panic when I start to dislike what I'm doing or that edge of fatigue before an injury that it's time to change it up.

Recently I started to use one of those phone applications that uses GPS to chart a run, has a timer and a way to measure how fast you're going. My tendency when I am using that program is to just run, and keep on running exactly the same way for as long as I can, to try to go faster, farther and increase the length and speed each time I run. While I didn't get injured from it, I also wasn't getting the kind of joy I got from simply moving until I felt like stopping, then moving again. Sometimes I go very slowly, sometimes faster. Sometimes I stop and take pictures. To me, a run is somewhere between a prayer and a meditation, and that's where it's at for me.

Finally, here are some pictures from my recent hikes/runs...

Daniel Lieberman's new article

It's finally out - a retrospective study comparing injury rates among 16 forefoot (not necessarily barefoot) runners and 36 rearfoot runners by Daniel Lieberman. Lieberman's conclusion was that rearfoot runners have more problems with "repetitive stress injury" than forefoot runners. Since I'm not a doctor I don't have access to the full article yet. I, for one, would like to know what "repetitive stress injury" is. Also, a retrospective study isn't, I think, as definitive as other types...again, it's not my field, so I just nod and say. Okay...more please?

The first thing I did was go searching for the name of the article to see what was being said. I saw, as usual, that all the pro-barefoot running sites were kvelling...honestly, I'm not sure it's time for that yet.

This one was where I felt I got the most information. I've found it before and it's always interesting. It's an international crowd of English-speaking podiatrists who all gripe at each other more or less constantly, some of whom have a clue and some who don't. At least one of them is fairly curmudgeonly about barefoot running with just as much or more bias that the most zealous barefoot running advocates. On the other hand, they are doctors and they have access to a wide range of studies and (presumably) know what they're looking at when they read them.

As someone who has run barefoot and minimally shod now for over a year, I can say that you do trade one set of possible injuries for another, especially as you make the transition. I don't hear much about that from the BF advocates, although you see it constantly on the BF running forums. I also hear constantly about the horrible injuries that rearfoot, thickly shod runners regularly experience. I can say from experience that my pain from running (and living) in shoes was much greater than any discomfort I've had from running barefoot.

What I don't see anywhere is the idea that transitioning from shod to barefoot running requires any kind of lifestyle change, which it does. The assumption is that when you transition to BF or minimal running that a runner will once again work competitively and repetitively to conquer miles upon miles of terrain with their feet.

Bare feet don't necessarily do that without a fuss, especially those that belong to someone who drives, sits and has worn supportive shoes all day most of their lives.

Barefoot work requires a certain amount of reverence for the earth and for our bodies. If that reverent attitude takes you miles on foot, then there you go, but my sense is that people follow trends more than they listen to their bodies. We are a culture that believes in conquests instead of experiences. History is ignored - if we paid attention to it there would probably be fewer wars and running injuries.

Being barefoot is a metaphor for the larger changes we need to make in how we live in the world. Maybe this is an unpopular attitude, but I think that we need to ditch the start and finishing lines and just get out there with our feet on the ground for a while, stop when we're tired, skip when we feel like it and use our senses to experience what we've been missing.
