It’s sad. And It’s obvious to those of us who were around during the 1960s and 1970s, when going barefoot everywhere was popular. Start early in the spring with short barefoot walks. Then longer each month, and by summer we were able to walk on the hottest pavement, sharpest rocks, no problems at all. How our shoe obsessed society forgot this and has to re-learn it is strange. I mean young people were shopping barefoot, running errands, working out in gyms (Arnold did his bodybuilding barefoot during the 1970s), anywhere in public places. Young people today apparently have no idea this even happened. They are so squeamish now. Everything is ‘ewww’ ‘gross’ ‘yuk’, with no knowledge of the biology around them, or the concept of risk assessment.
