Footloose in the hills, with no strings attached
Apart from being plain old footwear, shoes have several other uses. They can be used to garland wrongdoers, flung at perceived wrongdoers and dangling from a bumper, they may ward off the evil eye of potential wrongdoers. In the absence of the real thing, a strategically-placed painted shoe, preferably a jutti-style one with a long curvy front, may suffice to deflect intended malevolence to a hapless, shoeless vehicle.
