The interesting thing about that is 'barefoot walking' is all the rage as it's meant to be good for you in all sorts of ways, and a lot of people wouldn't think twice about it, even if your jeans were knee deep in mud, as, you know, "you didn't expect that to happen".
Of course, being completely covered in mud from head to toe is another story but I'm pretty sure that someone somewhere has a back story for when they got caught...
