Rules of toe wrestling are very similar to the rules of arm wrestling. To play, competitors must simply take off their shoes and socks, link toes with an opponent, and touch the soles of their feet to their opponent’s soles of their feet. From there, the sport is almost exactly like arm wrestling. Players must try to pin their opponent's foot to the ground for 3 seconds while trying to avoid the exact same thing. The sport has grown to be so big that it is now competed in professionally.
