I go barefooted as often as I can, including when I run and play soccer. Some caveats:
To run barefooted, one needs the right surface, as other posts to this thread have indicated, such as meadows, fields, and unpaved trails. A few hundred yards from my door, I can lace a network of these into a five-mile run, including alongside a stream in which I sometimes cool off mid-run. It's awesome.
I play soccer barefooted only when those with whom I'm playing are also doing so, for obvious reasons. Barefoot soccer involves a different way of ball handling, but not way different.
Living in the third world, though I see you don't, can be great in this regard. I lived in Papua New Guinea for two years, and went shoeless whenever I could, which was almost always, including while running and playing soccer and rugby. It's wonderfully sensual!
And if it's warm enough to run bare-footed, it's warm enough to run bare-chested! Here's to the Bohemian in you!
Thanks for raising the subject, and best of luck in your barefooted pursuits!
