The invention relates to an air-permissible sole material and a method for preparing air-permissible soles by the material, relating to a sole material and a method for preparing the soles by the material. The invention provides an air-permissible and water-proof sole material and a method for preparing the air-permissible soles which have good ventilation property and good wear-resistance, twist-resistance and anti-slipping functions. The composition of the sole material is rubber, 1, 2-polybutadiene, polystyrene, a lubricant and filler. The rubber, the 1, 2-polybutadiene, the polystyrene, the lubricant and the filler are mixed and put into an internal mixer for internal mixing; then, the internally mixed mixture is put into a granulator for granulation; and finally, the granules of the mixture are injected into sole moulds for injection molding by an injection molding machine. The sole material can provide passages and media necessary for ventilation; when falling on the ground, the pressure can cause vapor in shoe cavities to flow to the outside; when leaving the ground, the negative pressure causes the outside air to flow into the shoe cavities, therefore, the free-breathing of feet is realized and the soles have good wear-resistance, twist-resistance and anti-slipping performance.
