A show sole (1) includes a bellows portion (11) located at the heel section of the sole and a compressible space (12) is defined in the bellows portion. A spring unit (13) is located in the compressible space. At least one escape hole (121) is defined through a wall of the bellows portion. An insole (3) is mounted to the sole and seals the compressible space. Multiple pipes (122) extend from the compressible space and each has two open ends. One of the two open ends of each pipe communicates with the compressible space. When the compressible space is compressed, the air in the compressible space flows through the pipes and the escape hole. When the force is released from the compressible space, the air outside the shoe is sucked into the compressible space.
