Abstract

There is provided a ventilation shoe that allows for downsizing and enables a shoe interior to be sufficiently ventilated. The ventilation shoe comprises an upper (31), a sole (32) formed by layering a plurality of sole plates, and a ventilation device configured to take the air into a shoe interior (34) and release the air out of the shoe interior (34). The ventilation device comprises an air intake passage (L1) configured to take in the air, an air release passage (L2) configured to release the air, and a pump chamber (P) configured to feed the air taken in through the air intake passage (L1) to the air release passage (L2). The sole (32) is formed by layering a plurality of sole plates. The pump chamber (P) is formed in a flat shape between the sole plates. Valve mounting apertures (152, 157) are formed in a middle sole plate that is placed vertically between other sole plates. Each check valve (V1, V2) integrated via a support member is mounted to the valve mounting aperture (152, 157).

Abstract

The present invention enables downsizing of a ventilation shoe and enables sufficient ventilation of the interior of the shoe. The present invention has: an upper (31); a sole (32) obtained by stacking a plurality of sole sheets; and a ventilation device for taking air into a shoe interior (34) and discharging air outside the shoe interior (34). The ventilation device is provided with: an air intake passage (L1) for taking in air; an air discharge passage (L2) for discharging air; and a pump chamber (P) for feeding the air taken in through the air intake passage (L1) to the air discharge passage (L2). The sole (32) is configured from a plurality of sole sheets being stacked on one another, and the pump chamber (P) is formed in a flattened shape between the sole sheets, and valve installation holes (152, 157) are formed in an intermediate sole sheet that is sandwiched between other sole sheets from above and below, and check valves (V1, V2) are respectively provided in said valve installation holes (152, 157) in such a manner as to be integrated therewith via a support member.
