PURPOSE: A functional insole is provided to resolve the highly humid environment inside of a shoe by using an insole contacting with the bottom of a foot and to extend the usage effect and usage range of the shoe by adding functionality. CONSTITUTION: A functional insole is manufactured by using a corrugated cardboard material and forming a cut-out line, a crease line, a tailoring line, and a print line in the sheet form on a corrugated cardboard. The insole is able to be used by being assembled with a heel pump accessory or a heel seat accessory and also used in a form without a heel accessory. The heel seat accessory is assembled with a corrugated cardboard insole, and has an extrusion or injection structure adding functionality. The corrugated structure of the corrugated cardboard is installed in the heel-to-toe direction and is utilized as the air circulation path of a heel pump.
