1A to 6, the shoe sole and midsole assembly 10 according to the present invention is coupled to a non-slip shoe sole 100 having a structure that prevents slipping and reduces splashing of water, and the shoe sole 100 It is composed of a shoe midsole 200 having a structure capable of discharging the air inside the shoe to the outside.

The non-slip shoe sole 100 of the present invention includes an rim portion 101 protruding to a predetermined thickness along a lower surface thereof, and a plurality of non-slip protrusions 110 protruding from the inside of the rim portion 101.

The rim portion 101 of the shoe sole 100 is formed at the same height as the non-slip protrusion 110 and touches the ground with a plurality of non-slip protrusions 110 disposed in the inner space thereof, thereby enhancing stability when folded. It supports the non-slip protrusion 110 and serves to prevent it from being easily touched.

However, the rim unit 101 is formed with a plurality of water outlets 103 for discharging water to the outside in order to prevent water from splashing when walking on the ground on a rainy day. In addition, the rear end heel region of the shoe sole 100 is formed at the same height as the rim unit 101 or the non-slip protrusion unit 110, so that the space inside the rim unit 101 is formed in a diagonal shape as shown in FIG. 2A.

In addition, the guide unit 120 is made of a structure inclined upward of 30 to 45° toward the rear end together with the midsole of the shoe, as shown in the side view of FIG. 1C.

When the guide part 120 is combined with the water outlet 103, it is possible to significantly reduce splashing of water when walking where there is water on the ground.

In general walking, when the foot is on the ground, the heel touches first, and when the foot falls, the weight is placed on the toe and the heel is lifted. However, in the present invention, the water outlet 103 is formed in the rim portion 101 so that some of the water inside the rim portion is discharged to the left and right of the shoe when it touches the ground, and the water from the guide portion 120 is directed toward the heel. When the foot falls from the ground because the heel region in which the guide unit 120 is disposed is inclined upward along with the midsole 200 while preventing it from coming, it is discharged to the space between the rim unit 101 and the guide unit 120 When the heel is lifted, water can reduce splashing behind the user's ankle or towards the jangdanji.

The non-slip protrusion 110 is provided in a space between a plurality of elastic pieces 111 adjacent to each other so as to form a ring structure as shown in FIGS. 2A and 3, and a passage provided in the spaced space between the adjacent elastic pieces 111 ( 113) and an inner space 115 divided by a plurality of elastic pieces 111. 2A illustrates that the plurality of elastic pieces 111 have a hexagonal ring structure as a whole, but the structure is not limited thereto, and may be a circular ring or a polygonal ring structure as shown in FIG. 2B.

In the case of the hexagonal ring structure, each of the three elastic pieces 111 has a bent structure, and such a bent structure serves to prevent deterioration of durability. For example, in a hexagonal ring structure, if the elastic piece 111 is divided into six hexagonal sides instead of three and is a straight elastic piece, each elastic piece is easily bent or broken by the load on the ground, so to improve durability. It is preferable that it is an elastic piece of a bent structure as shown in FIG. 2A.

The outsole 100 shown in FIG. 3 (a) is a cross-sectional view of a state not touching the ground, and FIG. 3 (b) is a cross-sectional view of a state in which the non-slip protrusion 110 is closed when the outsole touches the ground, 3C is a cross-sectional view of a state in which the non-slip protrusion 110 is opened. When the non-slip protrusion 110 is closed as shown in (b) of FIG. 3 or opened as shown in (c) of FIG. 3 may vary according to the ground condition. However, when the non-slip protrusion 110 is closed as shown in FIG. 3(b), the passage 113 provided in the spaced space between the elastic pieces 111 is sealed, and conversely, as shown in FIG. 3(c), the elastic piece ( When 111) is opened, the passage 113 between the elastic pieces is also opened. Here, the passage 113 serves to discharge water from the inner space 115 of the non-slip protrusion 110 to the outside when stepping on the surface wet with water.

On the other hand, when the non-slip protrusion 110a has a rectangular ring structure as shown in FIG. 2B (a), each elastic piece 111a corresponds to a hexagonal ring structure in that it forms a bent structure, but the elastic piece 111a is bent. Since the angle is small as 90°, it is not easily bent or opened, and when the non-slip protrusion 110b has a circular ring structure as shown in (b) of FIG. 2B, it is easily bent or broken like a straight line that is not bent. As for the non-slip protrusion 110, it is most preferable that the three bent elastic pieces 111 form a hexagonal ring structure.
