Shoe having an elastic body

Abstract

Disclosed is a shoe provided with at least one elastic body, which is combined with the outer sole thereof, so that friction induced in the shoe itself can be reduced, thereby enhancing the endurance of the shoe, and the shock absorption efficiency of the shoe becomes excellent, thereby allowing walking to be easier. The inventive shoe provided with at least one elastic body includes a plate-type outer sole protection sheath ( 21 ), a plate-type elastic body ( 22 ) stacked on the outer sole protection sheath ( 21 ), an outer sole body ( 23 ) stacked on the entire area on the top of the outer sole protection sheath ( 21 ) including the top of the plate-type elastic body ( 22 ), and a block type elastic body complementarily fitted in the outer sole body ( 23 ).
