A sole of a shoe having a wave-shaped dual layer structure is provided to improve cushioning effects and to allow a user to walk as naturally and safely as possible even on a non-even surface. A sole(100) comprises a bottom sole(1) and a midsole(2) layered in order. The midsole(2) has a dual layer structure consisting of an upper hard layer(3) and a lower soft layer(4). The upper layer(3) is made out of a urethane foam resin, while the lower layer(4) is made out of a compressive sponge. The upper layer(3) and the lower layer(4) are formed in a wave shape together. The bottom sole(1) is made out of rubber of a urethane foam resin. Also, friction projections(6) are formed on the bottom sole(1) to ensure a good ground sensibility. |
