Humans trod the landscape of North America thousands of years earlier than previously thought, according to new research that confirms the antiquity of fossilized footprints at White Sands National Park in New Mexico using two further dating approaches.

Go barefoot as much as possible!

I run in vibrams (toe shoes) and the strengthening of the normal muscles and moving as “we’re supposed to” has really improved my general feeling of strength. My knees and legs and back feel “planted” as opposed to wrapped and cushioned and separated from the earth.

We have 3 hinges of movement between our toes and knees, shoes eliminate our use of these a lot.

Take your shoes off and run in grass and you’ll notice you’re on your toes and not your heels, the amount of spring your legs create is increased, it’s just more natural.

“The peasant walk” is how humans naturally flatfoot walk, shoes gave us a heel strike which is “wrong”

The position of foot strike varies as a function of stride length. Stride length and turnover are the two variables that determine speed. We heel strike in shoes because they allow a longer stride at the same turnover. Why not increase turnover and keep stride length short ? Because it uses more energy.

Just because we can heel strike doesn’t mean we should.
