[Detailed description of the invention]

FIELD OF THE INVENTION The present invention relates to waterproof and moisture-wicking soles particularly suitable for various types of footwear.

0002

BACKGROUND OF THE INVENTION Footwear having soles made from synthetic materials or rubber is widespread. Although such footwear is an inexpensive and practical product that can be easily mass-produced, it still has the drawback of poor ventilation with the outside through the sole of the shoe.

[0003] This makes the shoes uncomfortable for the user to wear, and may even cause "athlete's foot."

[0004] Against this background, shoe soles have been provided in which a moisture-wicking and waterproofing thin film is interposed between a tread provided with fine holes and an upper part provided with holes.

Although this conventional shoe sole is ideal for wicking moisture away from the foot, it has been found that it still suffers from a number of deficiencies. Among these, defects in which the micropores in the tread quickly become clogged, restricting or preventing air flow, have a major impact.

The aim of the present invention is to provide a shoe sole that overcomes the drawbacks of the known technology mentioned above.

[0007] Accordingly, the main object of the present invention is to provide a new and improved shoe sole that follows the characteristics of those currently on the market.

Another object of the invention is to provide a shoe sole that can be manufactured at low cost and commercially available at a competitive price.

At the same time, another object of the present invention is to provide a shoe sole that is comfortable for the user.

[0010] This aim, these objects and other objects will be apparent from the following description and are achieved by the waterproof and moisture-wicking sole specified in the claims.

Other features and advantages of the invention include:
This is evident from the detailed description of the embodiments below and the drawings. The drawings merely illustrate specific examples.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Refer to the drawings. The sole according to the invention comprises a tread 1 made of rubber or a similar material. Two outer bands 2 project upward from the periphery of this tread 1 and form a strong structure together with other parts. Micropores 3 are formed across the thickness of these bands.

These micropores 3 are conveniently placed over the entire length of each outer band 2 or over a portion thereof.

According to the invention, a moisture-wicking and waterproofing membrane 4 is disposed inside each outer band 2 and is constructed of the material commonly known under the trademark Gore-Tex or other equivalent materials. It is preferable to leave it there.

The sole further comprises a foot support part 5 made of rubber or a similar material. This foot support part 5 is integrated with the tread 1 to form a single unit.

The support part 5 of the foot is provided with a grid of transverse partitions 6 separated by grooves 7 and having bands 8 projecting along the periphery. Band 8 is the aforementioned outer band 2
It is located inside these bands in the region where , and is connected to these bands 2 via the edge 9 portion.

A hole 10 is formed in the inner band 8 at a location where it overlaps with the band 2. Consequently, these holes communicate with the interior of the footwear.

The hole 10 is arranged so as to be connected to the groove 7, and the foot can also pass air moving from the bottom part.

Therefore, the bottom part of the foot communicates with the outside through the hole 10, the membrane 4 and the micropores 3.

When this sole is used in conjunction with footwear, a moisture-wicking inner sole 11 is arranged above the foot-supporting part 5, and an upper part 12 made of moisture-wicking material is arranged above the foot support part 5.
For example, it is fixed to the inside of the band 8 using glue.

[0021] Care must be taken during assembly by applying adhesive or other material to the area where the incorrect micropores 3 are provided, the area where the holes 10 are formed, and the area where the thin film 4 is located. Care must be taken to ensure that there is no negative impact on

Furthermore, the tread 1 and the outer band 2, as well as the foot support part 5 and the inner band 8, ultimately form a single unit and must be assembled in such a way that no water can enter through the connections.

Techniques that can be used to manufacture the sole according to the invention include, for example, injection molding techniques.

According to this method, a structure can be obtained in which both the lower part and the side band parts are completely waterproof. This structure can wick moisture in the direction of the arrow as seen in the drawing.

[0025] Since the outer band 2 is provided with micro-pores, these micro-pores are not easily blocked, thus eliminating the drawbacks inherent in known moisture-wicking and waterproof soles.

What should be further noted is that when walking, the foot alternately compresses and expands the partition 6, and a kind of pumping action takes place at the point where the groove 7 is connected to the hole 10, sucking in outside air. , the air trapped inside the footwear can be forced out along with sweat and moisture.

The mechanical action performed by the footrests promotes moisture wicking, and the membrane 4 acts as a kind of check valve to drain moisture to the outside.

In fact, it has been found that the intended aims and objectives of the invention have been achieved.

The present invention is susceptible to various modifications and changes, all of which belong to the technical scope of the present invention.

Each structural part can be replaced by other technically equivalent elements.

In practice, the materials used can be selected depending on the application, and the dimensions can be varied as required.
