A shoe sole structure having air-ventilating and waterproof features, provided with penetrating air vents at certain regions of the shoe sole, the air vents being provided at an outer side thereof with a serrated elastic fin and laminated at an inner side thereof with an air-ventilating waterproof film, such that when the shoe sole comes into contact with ground during walking, the serrated elastic fin is compressed to seal the air vent, and when the shoe sole takes off from the ground, the serrated elastic fin recovers due to its elasticity to open the air vent, whereby warm and human air in-shoe is substituted by external fresh air due to pumping effect resulted from continuous closing and opening of the air vents by the serrated elastic fins so as to maintain in-shoe dryness.
