According to the linguist steven pinker, the plural of athlete's foot would be "athelete's foot." That's because athlete's foot is just a disease that can be found anywhere (but typically on feet). I knew a kid at my summer camp who had athlete's foot on his hands, under his pits, and between his toes. Then he got it in his throat. But he still had athlete's foot. Boy was he a sick kid.
