Abstract: Disclosed is a shoe sole having upwardly sloped front and rear sides, which is used to manufacture a shoe of which a rigid middle sole is installed at an upper surface of an outsole and a shoe sheath is attached to an upper surface of the middle sole, in which an arch-shaped groove is formed at the center of a lower surface of the outsole. A central cushion is attached to a lower surface of the arch-shaped groove so that the arch-shaped groove is filled with the central cushion. Non-slip sole attaching grooves are formed over the total lower surface of the outsole and an exposed surface of the central cushion. A non-slip sole is attached onto the non-slip sole attaching grooves.
