You don't need shoes

all so true!
I have started walking and biking barefoot and it's a LOT better....I have also a maltracking patella and plenty of problems in my legs, and walking barefoot on grass is the best possible physiotherapy.

Think about it. My father's generation - as all the earlier generations since the origin of time - would almost NEVER wear shoes. Shoes are a relatively recent invention, like the combustion engine, and it creates more problems than it solves - just like the combustion engine (of, if you believe that 6 degrees more for average Earth temperature, due to excessive CO2 and methane from combustion engines and heating, is not a problem, wait and see year 2100, when few survivors will have to live in caves to escape from the fury of hurricanes and 500 Km/h winds).
