This search query made me giggle, so I wanted to share it.
I'm not sure that the author of that question could find the answer on my blog. In fact, I would advocate walking barefoot on the beach, on the mountain, wherever your wandering feet take you... as long as there's no broken glass or hypodermic needles. Some of the best rock climbers climb barefoot.
Just for the record, I don't advocate walking barefoot at work (except in the privacy of your own office, or maybe at an off-site, outdoor retreat). Nor do I suggest walking barefoot on public transit (though I've seen it done), in crowded dance clubs and bars (smashed tootsies), or in restaurants (against health code). You can probably get away with it at the symphony, though, if you wear a long down/ floor length pants.
Here ends today's public service announcement.
