Abstract: A shoe is provided with an air pumping device capable of supplying fresh air from the ambient atmosphere into the interior of the shoe. The air pumping device is detachable from the shoe so that it can be cleaned to remove dirts or alien objects that may block the air flow path. The air pumping device is located beneath the forepart of a foot wearing the shoe.
