PROBLEM TO BE SOLVED: To eliminate the stuffiness and discomfort of feet after wearing shoes for long, causing the malodor or the athlete's foot especially in summer. SOLUTION: A hollow (a pump function with a valve) 5 made of an elastic member is disposed in the heel part of the insole of a shoe, and tubes are disposed up to the toe part. When the heel part is raised in walking, air is stored in the hollow (the pump function), and air is jetted from air apertures 1 formed in the root of the toes when the shoe touches the ground. Air in the shoe is circulated whenever the user walks, so that the stuffiness is eliminated, and the space between the toes is always dried and kept clean. COPYRIGHT: (C)2007,JPO&INPIT
