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).
