Workout of the Day

Seven rounds for time of:
185 pound Front squat, 3 reps
7 L-pull-ups

A critic of barefoot running and minimalist shoes that facilitate barefoot style running states his case. Barefoot Running Shoes: How Effective Are They?, by Dr. Robert Kornfeld, podiastrist.  Because you are all well versed in Pose Method running, you should be able to spot the flaws in his thinking.  Post thoughts to comments.

    Dr. Kornfeld assumes that people running in VFFs are still going to heel strike, and that in turn is going to stress the metatarsals. However, I think he makes a good point about being evolved to run on uneven grass/dirt instead of pavement. And, I can tell you from my experience that even running POSE style, I’m putting stress on my big toes that I don’t get from running. One of my running buddies has been working on his stride mechanics for the last 14 months or so, gradually transitioning over to more and more training runs in VFFs (like four or five days a week). This is a guy with a 36 minute 10K who runs about 30 to 50 miles a week. He is sitting out right now with a metatarsal stress fracture. This is a data point of one, and people get metatarsal stress fractures all the time in conventional running shoes, so it isn’t like VFFs have a corner on those injuries.
    I’m running in my VFFs about one day a week and racing/doing long runs in a pair of Nike Air Skylons. I had no injuries or problems of any kind during 2010. My thinking is that my next pair of shoes will be something in between the Skylons and the VFFs. There are a bunch of minimalist running shoes on the market now; this guide is pretty useful in describing what you are looking for and giving a rundown of the current models:

  • Bethanie

    I broke a metatarsal once…I wasn’t wearing vibrams or running…
    Anyway, this is goal setting/measuring week. For that reason tomorrow is a one time opportunity. It is a scheduled rest day and therefore will allow people to do a workout/lift they either set a 2010 goal on and never got to re-test or want to do a “before” measurement/benchmark for a 2011 goal.

    AH– I too Bethanie have had a broken Metatarsal and I was not running or wearing Vibrams either ….
    wow .. today that’s about all I got

    I am currently stuck on a conference call, which means I will be doing the workout of the day at 7. That said, and as usual, the prescribed weight, even when scaled for women, made me LOL. Don’t worry, the mute button is on. I will, therefore, reduce the weight significantly in order to apply intensity. And that’s about all I’VE got! Also, I had a dream last night that someone told me I couldn’t do box jumps, and I punched them in the nose. Let’s hope 2011 doesn’t spell the return of Angry MoMo, since I kept her under wraps for most of 2010.

    Very cool article, but I’ll tell you that if you want a good business idea, create a running flat for Crossfit. I’ve been looking for the Inov-8 230 in a size 9.5 since before Christmas and I can’t find them anywhere (and no, I’m not doing the pink with orange, or the black/aqua, etc). Steve’s post gave me some ideas, and I searched for a few models and they’re out as well. Jeez. I was hoping to have them by the time I got back and even tossed my Zoots thinking I would have them by now. Looks like I’m going foot comando.

    Kornfeld’s use of language is so imprecise that it’s hard to tell what the hell he is talking about. Does he think the mechanics of walking and running are the same or different? At times he appears to think that barefoot running is done with a heel strike, but if so, then why does he conclude that barefoot running puts more stress on the 1st metatarsal? He also says that barefoot style of running on pavement will cause injury problems “downstream” of the foot and ankle. What is “downstream” from the foot besides the road? My experience is that people, including experts, who are confused and imprecise in language are also confused in their thinking.
    I think that Kornfeld’s other error is more important. He assumes that correct running involves finishing the stride by pushing off, including pushing with the toes, which he thinks make a significant contribution. He apparently thinks the toes contribute to forward propulsion. In Pose Method we believe forward propulsion comes entirely from gravity, via leaning. Barefoot running and minimalist shoes facilitate only one element of Pose Method, the forefoot landing. But Pose Method also requires that the foot be pulled from the ground as or just before the weight moves onto the toes. There should be no pushing off or extension of the leg out the back. There is no pushing off with the toes or anything else. Pushing off is bad mechanics, and leads to all sorts of problems with how the leading foot lands. And bad mechanics cause injury.
    The most difficult aspect of Pose Method is learning to pull. Pushing off is a hard habit to break.
    It is not surprising that Dr. Kornfeld thinks that pushing off is correct mechanics. Most people think this, and, in this respect, Dr. Romanov’s theory runs counter to the consensus.
