Functional shoe having a cushioning function and an air circulation function

Abstract

A functional shoe pertains to a cushioning function and an air circulation function, which integrally performs the cushioning function and the air circulation function. The functional shoe includes: an insole ( 110 ) and a midsole ( 120 ) having a tunnel portion ( 122 ). The tunnel portion ( 122 ) has a lower surface ( 122 a ) and an upper surface ( 122 b ) having a predetermined angle (α) with the lower surface ( 122 a ); an outsole ( 130 ) having an anti-slip tread ( 132 ); a foldable resilient member ( 140 ) having a support portion ( 142 ) for supporting the lower surface ( 122 a ) of the tunnel portion ( 122 ), and a rotating portion ( 144 ). The rotating portion ( 144 ) is resiliently folded by the load being applied thereto; a sealing member ( 150 ); and an air channel ( 160 ) having one end communicated to the closed tunnel ( 122 ) and the other end located at the front end of the insole ( 110 ).
