There are as many reasons for being barefoot as there are people going barefoot. "Connection to the earth" is only one of them. For me, wearing shoes would be like wearing boxing gloves; the loss of interaction with my environment, be it natural or man made, would be misery. Furthermore, cities have tons of great textures. Here's a great example of four different types of paving in one spot I encountered last year in Krakow, Poland: In terms of safety, I've walked barefoot without incident in literally hundreds of cities on four continents, including majors such as New York, Washington DC, Hong Kong, Bangkok London, Paris and Berlin. Experienced barefooters have very tough soles and know how to walk properly to avoid injury in even the roughest environments.
I walk around outside all the time barefoot, I know how tough feet can be... I do understand what you are saying... I guess I'd rather step on slug spit then human...
Some people are very much not into the holy bliss of being in direct touch with mother earth via their soles. Some do. To each their own. ommmmm
Well, as far as barefooting in high school goes, my own experience is not too recent, since I graduated in Germany in 1987... and back in the 1980s, the hip people in their typical outfit - including bare feet - were quite active in the peace movement, the upcoming eco movement and the one-world movement. I, myself, was part of those, too, and went to school barefoot quite often. The only time I had someone making noises was a grumpy chemistry teacher, telling me "I wouldn't let in my class barefoot..." to which I replied a little defiantly "Well, I'm not in one of your classes, am I?" and left him standing where he was with a sour look on his face. We were lucky not to have any dress codes or the like which banned bare feet - so I guess I had (at least in this respect) quite an easy time at high school.

Man ... oops , I meant, God, this grand rite will definitely drag huge human crowds before Your feet.
