I have the idea that running shoes are based on a kind of cult idea - that our feet are flawed and we need shoes to correct those flaws. The shoe companies are in the business of selling shoes. But there's no evidence from running shoe manufacturers that they're right. There's no scientific data that running shoes reduce injury.
Interpretation
The quote challenges the assumption that running shoes are necessary and beneficial for preventing injury.
Christopher McDougall's quote critiques the running shoe industry by suggesting that the belief in the necessity of specialized shoes is more of a cultural construct rather than a scientifically backed fact. He points out the lack of evidence supporting the idea that these shoes correct natural flaws in our feet, ultimately questioning whether they indeed help prevent running injuries or if they are merely a product marketed by companies seeking profit.
In practice
During a running community event, when discussing the pros and cons of running gear.
Humans are built for endurance, not speed. We're awful sprinters compared to every other animal. We try to run our races as if they were speed races, but they are not. They're endurance races. Even a marathon, the way it's run now, it's not an endurance contest.
Every morning in Africa, a gazelle wakes up, it knows it must outrun the fastest lion or it will be killed. Every morning in Africa, a lion wakes up. It knows it must run faster than the slowest gazelle, or it will starve. It doesn't matter whether you're the lion or a gazelle-when the sun comes up, you'd better be running.
Know why people run marathons? …Because running is rooted in our collective imagination, and our imagination is rooted in running. Language, art, science; space shuttles, Starry Night, intravascular surgery; they all had their roots in our ability to run. Running was the superpower that made us human — which means its a superpower all humans posses.
Way before we were scratching pictures on caves or beating rhythms on hollow trees we were perfecting the art of combining our breath and mind and muscles into fluid self-propulsion over wild terrain.
Anyone can do running. Running should be easy. It should be fun. It should include everyone. It shouldn't be a punishment for eating cheesecake, which is what we've turned it into.
Perhaps all our troubles - all the violence, obesity, illness, depression, and greed we can't overcome - began when we stopped living as Running People. Deny your nature, and it will erupt in some other, uglier way.
Science cannot solve the ultimate mystery of nature. And that is because, in the last analysis, we ourselves are a part of the mystery that we are trying to solve.
The real reason why general relativity is widely accepted is because it made predictions that were borne out by experimental observations.
The sensitive plate, the gas which is ionised, the fluorescent screen, are in reality receivers, into another kind of energy, chemical energy, ionic energy... luminous energy.
A black hole really is an object with very rich structure, just like Earth has a rich structure of mountains, valleys, oceans, and so forth. Its warped space whirls around the central singularity like air in a tornado.
The separation of science and non-science is not only artificial but also detrimental to the advancement of knowledge. If we want to understand nature, if we want to master our physical surroundings, then we must use all ideas, all methods, and not just a small selection of them.
Pluto's orbit is so elongated that it crosses the orbit of another planet. Now that's... you've got no business doing that if you want to call yourself a planet. Come on, now! There's something especially transgressive about that.
