While modern shoes and athletic outfits offer some benefits to competitors, the psychological impacts of not wearing clothes might outweigh the physical effects. Ancient Greek legend has it that in 720 BC, an Olympic athlete named Orsippus of Megara was competing in the 185m run when his loincloth slipped off. Rather than stop to hide his shame, Orsippus sprinted on and won the race. His triumphant example stuck. Nude athletic competition – often emphasized through the liberal anointment of olive oil – became all the rage in Greece, seen as the ultimate tribute to Zeus.
