Dan Lieberman on Running Form

Posted by | Posted in Barefoot Running, Training for Running | Posted on 06-08-2012

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 (who turned me onto the following video), and thanks to Tuck at (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.

Randy Kreill’s Marathon Huarache Tying Technique

Invisible Shoe customer Randy Kreill the opposite of me.

I’m a “short sprinter”. The 100m and the 60m (indoor) are my races of choice. I run a 200m under protest. And, yes, I’m also a “short sprinter” in that I’m 5’5″ ;-)

Randy, on the other hand, is a tall, ultra-runner.

Here’s a picture of him finishing up his first 50k in his 4mm Connect barefoot sandals.

Personally, I don’t even like to DRIVE 50k. ;-)

Randy is also one of those guys who likes to experiment. He started with the basic huarache tying pattern, but tweaked it to something he uses for his long-distance runs. It’s not a slip-on/slip off style, but you can lace it up pretty quickly. It has a bit of a toga-style look about it. And one thing it does nicely is pull the ankle holes up around your foot.

If I were going to use this style (just the tying style…trust me, I won’t ever consider running ultra-distances), there are two things I’d consider changing.

  1. Add another knot under the outside ankle hole once you’re confident that you have the various lace lengths correct. If you do this, you’ll have to adjust the lengths, since adding a knot will shorten the toe strap or heel strap, depending on how you tie it. What this will do is further “lock in” the lacing.
  2. Coat those ankle knots with a layer of epoxy or Shoe Goo. While this style pulls the ankle holes off the ground nicely, the knots add a bit of extra material that’s closer to the ground. Add this to the fact that when people are just starting out with long-distance barefoot-style running, they tend to lose their form when they get tired. If you really lose it, you could end up heel-striking or scraping your feet a bit. If you do either of those, you could put some friction on those knots under the ankle holes. The Shoe Goo or epoxy will add some extra protection to the laces in those spots.

One of my favorite things about the barefoot running / minimalist footwear movement is that people are experimenting and coming up with more ideas and improvements to 15,000 year old ideas (like barefoot sandals) in the last 2 years than there have been in the last 14,998 years.

Keep it up everyone.

And good luck, Randy, on those amazing runs!

4 Reasons NOT to Run Barefoot

Posted by | Posted in Barefoot Running, Barefoot Running Shoes, Huaraches, Training for Running | Posted on 29-12-2011

[This post is guest-authored by our friend Rob Raux from]

Being barefoot and running barefoot is a blissful and consciousness-expanding endeavor. The feedback supplied from the ground is powerful enough to force even experienced runners to try it for only a mile or so, if they make it that far. Barefoot running, however wonderful, should not be subscribed to dogmatically.

There are myriad resources available expounding on the benefits of being barefoot. Most of their reasons, methods, and warnings have merit. Unfortunately many of them sway to heavily towards the one-size-fits-all solution.

Experiencing life unshod isn’t always the best option. Putting on a pair of huaraches or other minimalist shoes can serve a number of beneficial purposes:

  1. Technical Trail Running.
    Many people worry that the rocks, twigs, and roots on a trail make barefoot trail running impossible. Not true. First, you use your eyes and avoid what worries you. Second, your feet aren’t rigid and can grab and grip and mold around many “obstacles.”

    That said, while there’s nothing better than feeling the grass beneath your feet, having your heel land on an embedded rock leaves something to be desired. To be more specific, it could leave behind a bruise that will take at least a week to heal.

    That doesn’t include the chance of damaging the fatty tissue which protects your heel bone from impacting the ground. If any of this sounds painful, trust me, it’s worse than you’re picturing.

    A trail has hazards which you may not wish to risk if you’re still an inexperienced barefooter. When a single false step means a week of no running, it’s just not worth it to be ideological about keeping yourself unshod.

  2. Additional mileage
    Your body may be able to take additional mileage, but the bottoms of your feet may not be ready to support it yet barefoot. Now, if you’re looking to become a better barefoot runner, this is good news — when your skin tells you to stop… STOP! Over time it’ll adapt (not callous) and you’ll be able to put in more miles.

    Until then, there’s nothing wrong with protecting your precious footsies, but only if you know your form is correct. If you are transitioning from shoes to barefoot and have yet to perfect the change from heel strike to mid foot strike or a forefoot strike, don’t ask for trouble by adding more miles in a minimalist shoe. You’ll find yourself injured promptly and thoroughly.

    If you are comfortable in your stride, you will find that your feet hit a natural point where further barefoot running may only lead to blisters (that usually means your form has broken down and you’re pulling/pushing the ground, instead of placing/lifting). In these cases, adding a protective covering will give you the opportunity to add those additional miles you crave.

  3. Racing
    A foot covering increases your margin for error while running. Proponents of barefoot running tout the pain feedback loop as a beneficial aspect. Any foot covering blocks the pain receptors, which allow you to cause more damage to your body.

    In a race, this can be a necessary evil. A reduced pain feedback loop allows you to run a longer duration of more intensity. The covering may also absorb some of the mistakes you may have made barefoot (stepping on that rock in your mental fatigue).

    There’s obviously a very fine line to be ridden here, and one that you can certainly go too far with. Go with the least amount of covering possible and you should be able to dampen and absorb just the minimal amount of error to improve your results.

    I’d love to say, “If you’re not comfortable running that distance, don’t race that distance.” But I know how some of us… I mean, YOU… can be ;-)

  4. The bitter cold
    Mother nature yields to no man. Don’t even think about getting the best of father winter.

    If you live in a climate that has a true winter, you know what frostbite feels like. Now try running barefoot.

    Amazingly, there are folks who do it, and enjoy it. And check out Steven shoveling snow in his huaraches. Frankly, I’ve tried it and even I think that’s crazy. Most people are going to need something to keep their feet protected from the elements (wind, snow, slush, etc.). Each person has a different tolerance, which will adapt as they get more comfortable with the colder weather.

    When dealing with the elements it’s best to be safer than pull up limp 3 miles from your house and walk the rest of the way home.
