ABSTRACT:
An outsole of a shoe including a plurality of throughout hole formed at its heel portion, its middle portion and its toe portion, thereby achieving lightness of the shoe and improvement in cushion effect. A pressing protrusion which is formed at the middle portion of the outsole by the throughout hole provided at the middle portion of the outsole contacts frictionally the concave portion of the wearer's foot, thereby providing the foot-pressing effect for health. The throughout hole provided at the middle portion of the outsole generates an effect of softly massaging the concave portion of the wearer's foot being pressed by the pressing protrusion, by virtue of its air cushion. An inclined surface which is provided at the upper surface of the toe portion of the outsole serves to prevent the feet of the wearer from outwardly diverging in the inverted-V form during walking.
