There’s so much jumbled misinformation here, that I can’t address them one by one.
First off, almost ALL Kenyans start off their lives running barefoot. They run from home to school (usually an AVERAGE of 4 to 5 miles) Then run home for lunch, then run back to school, then run home and do chores, or if they live on a farm, do farm work. That’s an average of 20 miles a day, every school day. Barefoot.
Running barefoot has numerous benefits. I’ll give you the big 3 that the average American can get out of starting to run barefoot.
1>) it will strengthen the tendons and stabilizer muscles in the feet and ankles. The MAJOR benefit here is that you will never, ever sprain your ankle again. In high school I started running barefoot 1 mile a day (at the end of every 6 mile distance run) I did this for 3 years. To this day, I’ve turned my ankle over in a pot hole to the point that the bottom of my shoe scraped the inside of my leg and I just shook it off and kept running with no damage.
2) It gives you a Much more explosive toe off. IOW, when sprinting, the little flick that your trail leg, foot does is much more powerful. (this is hard to explain to non runners.)
3) It strengthens your calves immensely. I don’t feel like describing why strong calves help running.
One thing the guy in that article said was totally true… heel-toe is not only inefficient and hard on your joints… it’s unnatural. Whenever I would try to convert people to running on their toes, I would take them to a grass lawn or field, and make them run at a near sprint without their shoes. Much to their amazement, they would automatically be up an the balls of their feet. It’s how humans were built to run.
As a disclaimer, I really don’t think a lot of things in that article (which I only skimmed) were a good idea. First, if you’re going to run barefoot at all, ease into it. Like I said, I would only do a mile every other day. And this was on a grass field. Second, running barefoot on roads is a very unnecessary danger. The most obvious reason being glass. And third, he blames shoes, and running improperly, interchangeably. This is stupid. You can learn to run properly AND wear shoes.
As someone pointed out, this is GQ, so I will give my credentials. I have been competing for 13 years as a runner. I trained under a world record holder, and spent 5 years at running camps when I was younger. I’ve trained with some of the best in their fields. The Kenyan info comes from a coach who was allowed to spend 2 weeks with the Kenyan National Cross Country team. He came back to the states, and came to our running camp to tell us essentially why the Kenyans are superior to us in almost every aspect of running, including mentally.
There’s more, but this is a long enough post. Hope it helps
