In actual use, the present invention communicates with the outside air through the fifth through hole 41 , and this structure can avoid generating water pressure in the fifth through hole 41 , thereby significantly improving the water resistance of the large bottom layer 4 . As we all know, the distribution of pressure on the sole of the foot is not uniform. When the large bottom layer 4 is in contact with water, due to the pressure distribution, some parts of the large bottom layer 4 will generate higher pressure, such as the metatarsals and the part under the heel, while other parts, such as The part under the midfoot will have less pressure. When the water pressure in the fifth through hole 41 of the high pressure part of the large bottom layer 4 rose, the water would be guided to places with lower pressure by the connected passage 42, and at these places, water would flow out of the large bottom layer 4 through the fifth through hole 41. Therefore, no water pressure will be generated. In this way, the water resistance performance of the large bottom layer 4 can be obviously improved.
