We all know that barefooting was more common in the past. However, it was not that there were that many people who went barefoot all the time, but that they didn’t have the qualms about doing so when the occasion seemed right (saving one’s shoes, e.g., while plowing a field), or as a kid growing up.
Thus, even back then, those who never wore shoes were part of local color, and tended to get written about (just like today!).
