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.

Given that the only record we have of them are some footprints in the middle of a desert, I think finding their tools is going to be a little more challenging.
More than anything, though, I think this demonstrates just how non-permanent human civilisation is.
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.
Wearing the wrong length/width/shape shoe will indeed mess up your feet. Wearing the correct size/shape shoe for your individual feet will not give such issues. Additionally different shoes do different things so wearing the best one for the activity being done will yield the best results.
Changing to different shoes every day is also really important to dry out sweat and avoid repetitive injuries caused by wearing the same shoe such as corns, callouses, deformations, stress fractures, etc.
That said, cheap material and lack of local shoemakers, makes finding the good/best fit incredibly difficult if not impossible. Couple with feet size shifting throughout the day (swelling) and the changes over a lifetime, really makes everything more complicated. And that's not even acknowledging prices or fashions.
If he existed at all and isn't just the amalgamation of stories about ancient first century Jewish prophets.
Asking if Jesus existed as the gospels claim is like asking if Robin of Loxley had merry men or if George Washington chopped down a cherry tree and made dentures out of it.
Eventually myths become added to the historical man/men until only the myths remain.
