Disclosed is a shoe having a foot-sole-contacting surface on which air passages extending along a plantar artery are formed to allow ventilation and prevent compression of the plantar artery. The shoe includes an upper having a space for accommodating a foot of a wearer, and a shoe sole including an insole accommodated in the space. The insole has a surface in contact with a foot sole of the wearer, and a plurality of air passages is engraved on the surface of the insole so as to extend along a plantar artery projected onto the foot sole.
