[0008] According to the present invention, it is possible to provide shoes that maintain their strength while quickly draining water from inside the shoe with a simple drainage structure, and that maintain a certain level of quality. [Brief explanation of the drawing]

[0009] [Figure 1] This is an exploded perspective view of a shoe according to Embodiment 1. [Figure 2] This diagram schematically illustrates how the first slit and the second slit intersect to form a drainage hole. [Figure 3] This is an exploded perspective view of a shoe according to Embodiment 2. [Figure 4] This is a disassembled perspective view of a shoe according to Embodiment 3. [Modes for carrying out the invention]

[0010] The shoes of this embodiment are primarily worn near water, such as for stream climbing or fishing in mountain streams and rocky shores, and the invention relates to a structure for draining water that enters the shoes. Shoes 1, 2, and 3 according to this embodiment will be described below with reference to the figures. In this embodiment, the bottom side of the shoe is defined as the bottom, and the opposite direction is defined as the top. This direction will be used as a reference point below. This direction is used to explain the embodiment and does not limit the direction in which the embodiment of the present invention is actually used.

[0011] (Embodiment 1) Figure 1 is an exploded perspective view of shoe 1. As shown in Figure 1, shoe 1 comprises a shoe body 10, an insole 11, an adhesive plate 12, a first sole 13, and a second sole 14.

[0012] The shoe body 10, also referred to as an upper, is formed of natural leather, synthetic leather, or fibers. An insole 11 is inserted inside the bottom portion 10a of the shoe body 10. The insole 11, also called an inner sole, is detachably disposed inside the shoe body 10. The insole 11 is a portion that directly contacts the sole of a foot inside the shoe body 10, and improves the fitting feel of the shoe and absorbs impacts. The insole 11 is formed by attaching a lining material to the surface of a base sponge material. As the material for the sponge material of the insole 11, a material having impact absorption properties and elasticity is preferable; for example, EVA resin (ethylene-vinyl acetate resin), EVA resin foam, PU resin (polyurethane resin), or the like is used. A plurality of first drainage holes 11a are formed on the toe side of the insole 11. Here, the "toe side" refers to a position where a portion corresponding to the forefoot of a foot makes contact. This position is the lowest location inside the shoe, and is a portion where water that has entered the inside of the shoe 1 easily accumulates.

[0013] The adhesive plate 12 is a sheet-shaped member for attaching the first sole 13 to the bottom portion 10a of the shoe body 10. The adhesive plate 12 is attached to the shoe body 10 by being sewn onto the bottom portion 10a of the shoe body 10 or adhered thereto with an adhesive. Various materials can be used for the adhesive plate 12 depending on the type of shoe. For example, for shoes intended for walking on relatively flat roads, a thin paper or fibrous adhesive plate is used, and for shoes intended for walking in areas with many rocky outcrops, a thick resin adhesive plate is used.

[0014] A first slit 12a is formed on the toe side of the adhesive plate 12. The first slit 12a is formed at a position facing the first drainage hole 11a formed in the insole 11. Two first slits 12a are formed parallel to the length direction of the shoe 1. The number of slits is not limited to two, and may be one or more than two.

[0015] Since the adhesive plate 12 is attached to the bottom surface of the shoe body 10 while tension is applied thereto in the length direction, it is weak against forces in the width direction. Therefore, by forming the first slits 12a parallel to the length direction of the shoe, the strength of the adhesive plate 12 can be ensured.

[0016] The first sole 13, also referred to as a midsole, forms the sole of the shoe 1 together with the second sole 14. The adhesive plate 12 and the first sole 13 are bonded to each other with an adhesive. The first sole 13 is formed of a material having cushioning properties, for example, formed of EVA, PU, or TPU (thermoplastic polyurethane). On the toe side of the first sole 13, a second slit 13a is formed at a position facing the first slit 12a. The second slit 13a is formed so as to intersect the first slit 12a. In the present embodiment, three second slits 13a are formed parallel to the width direction of the shoe 1, but the number is not limited to three.

[0017] The second slit 13a is formed on the toe side of the shoe 1, and this position is where the first sole 13 bends when a wearer of the shoe walks. By forming the second slit 13a at this position, the first sole 13 is deformed so as to flexibly follow the movement of the foot of the wearer of the shoe 1.

[0018] As schematically shown in Fig. 2, the two first slits 12a and the three second slits 13a intersect substantially orthogonally, and six second drainage holes 4 communicating the adhesive plate 12 and the first sole 13 are formed at the intersecting portions. In Fig. 2, five second drainage holes 4 are shown. In the present embodiment, six second drainage holes 4 are formed by the intersection of two first slits 12a and three second slits 13a, but the number of the second drainage holes 4 can be changed depending on the combination of the numbers of the first slits 12a and the second slits 13a.

[0019] The second sole 14 is formed of felt fabric, and includes a ground contact surface 14b at a lower portion thereof. The felt fabric is formed into a plate shape by pressing natural fibers such as sheep wool and camel hair or synthetic resin fibers, and has water permeability. By forming the second sole 14 from felt fabric, the wearer can walk stably in slippery places with slime or moss.

[0020] The upper surface of the second sole 14 is divided into a first region 14a facing the second slit 13a and a second region 14c other than the first region. Adhesive is applied to the second region 14c to bond the first sole 13 and the second sole 14. The area to which the adhesive is applied may be the entire second region 14c or only a part of it. Furthermore, the first region 14a may be an area that includes at least the area in which the second drainage hole 4 is formed.

[0021] By not applying adhesive to the first region 14a, water that passes through the second drainage hole 4 seeps from the first region 14a into the second sole 14. The seeped-in water permeates the entire permeable felt fabric and is discharged from the entire contact surface 14b of the second sole 14.

[0022] When water enters the inside of the shoe 1 having such a structure, the infiltrated water passes through the first drain hole 11a of the adhesive plate 11, through the second drain hole 4 formed by the first slit 12a and the second slit 13a, into the first region 14a of the second sole 14, and is discharged from the contact surface 14b of the second sole 14.

[0023] According to this embodiment, the second drain hole 4 can be easily manufactured by forming the first slit 12a and the second slit 13a in an existing material such as a sole.

[0024] According to this embodiment, the first slit 12a and the second slit 13a can be intersected to form the second drain hole 4, allowing for easy water discharge with a simple structure.

[0025] According to this embodiment, water can be quickly drained from areas of the shoe 1 where water tends to accumulate through multiple second drainage holes 4. Therefore, the shoe 1 dries faster, and the wearer can continue walking comfortably without feeling any weight after getting out of the water.

[0026] When circular or other shaped holes are formed in both the adhesive plate 12 and the first sole 13 to serve as drainage holes, positioning the two holes to connect them is difficult. However, according to this embodiment, the second drainage hole 4 can be easily formed without positioning simply by forming it at a position where the first slit 12a and the second slit 13a intersect.

[0027] According to this embodiment, by providing a first region 14a on the second sole 14 where adhesive is not applied, and applying adhesive to the second region 14c, water accumulated in the shoe 1 can be drained by utilizing the water permeability of the felt while maintaining the adhesive strength between the first sole 13 and the second sole 14.

[0028] (Embodiment 2) Figure 3 is an exploded perspective view of shoe 2. As shown in Figure 3, shoe 2 comprises a shoe body 20, an insole 21, an adhesive plate 22, a first sole 23, and a second sole 24.

[0029] The structure of the shoe body 20, insole 21, and adhesive plate 22 is the same as that of shoe 1, so a detailed explanation will be omitted. The insole 21 has a plurality of first drainage holes 21a, and the adhesive plate 22 has two first slits 22a that are parallel to the length direction of shoe 2.

[0030] The first sole 23 is molded from the same material as the first sole 13 of the shoe 1, and has three long grooves 23a formed on the toe side parallel to the width direction of the shoe 2. Both ends of the long grooves 23a extend to the side of the first sole 23 and open up, forming an opening 23b.

[0031] As shown in Figure 3, the first slit 22a formed in the adhesive plate 22 and the long groove 23a formed in the first sole 23 are arranged substantially perpendicular to each other, and six second drainage holes 4a are formed where the first slit 22a and the long groove 23a intersect. The number of second drainage holes 4a can be changed by the combination of the number of first slits 22a and long grooves 23a.

[0032] The second sole 24 is made of rubber. Although not shown in the illustration, the underside of the second sole 24 has multiple bumps and grooves to increase the coefficient of friction when in contact with the ground. Since the second sole 24 is made of rubber, forming circular holes in the sole itself is not desirable from a strength standpoint, and therefore the second sole 24 does not have a drainage mechanism.

[0033] If water enters the inside of the shoe 2 having such a structure, the infiltrated water passes through the first drainage hole 21a of the adhesive plate 21, through the second drainage hole 4a, and is discharged from the opening 23b of the first sole 23.

[0034] According to this embodiment, water that has passed through the second drain port 4a can be discharged from the opening 23b of the first sole 23, so that the drainage function can be achieved without forming holes in the second sole 24 which is molded from rubber. Furthermore, it can be applied to shoes worn near water, regardless of the material of the second sole 24.

[0035] (Embodiment 3) Figure 4 is an exploded perspective view of shoe 3. As shown in Figure 4, shoe 3 comprises a shoe body 30, an insole 31, an adhesive plate 32, a first sole 33, and a second sole 34.

[0036] The structure of the shoe body 30, insole 31, and adhesive plate 32 is the same as that of shoes 1 and 2, so a detailed explanation will be omitted. The insole 31 has a plurality of first drainage holes 31a, and the adhesive plate 32 has two first slits 32a that are parallel to the length direction of the shoe 3.

[0037] The first sole 33 is molded from the same material as the first sole 13 of the shoe 1, and has three second slits 33a formed parallel to the width direction of the shoe 3 on the toe side.

[0038] The second sole 14 is made of rubber material and has a third slit 34a formed therein. The third slit 34a is formed parallel to the first slit 32a and positioned at the same location on the shoe 3.

[0039] As shown in Figure 3, the first slit 32a formed in the adhesive plate 32 and the second slit 33a formed in the first sole 33 are arranged approximately perpendicularly, and six second drainage holes 4b are formed at their intersection. The second slit 33a formed in the first sole 33 and the third slit 34a formed in the second sole 34 are arranged approximately perpendicularly, and six third drainage holes 4c are formed at their intersection, although only one is shown in the figure. The number of second drainage holes 4b and third drainage holes 4c can be changed by the combination of the number of first slits 32a and second slits 33a, and the combination of the number of second slits 33a and third slits 34a.

[0040] If water enters the inside of the shoe 3 having such a structure, the water that has entered will pass through the first drainage hole 31a, the second drainage hole 4b, and the third drainage hole 4c of the insole 31 and be discharged from the contact surface 34b of the second sole 34.

[0041] According to this embodiment, the first slit 32a, the second slit 33a, and the third slit 34a can be combined to form the second drain hole 4b and the third drain hole 4c, so that the water accumulated in the shoe 3 can be efficiently drained from the contact surface 34b of the shoe.

[0042] The present invention is not limited to the embodiments described above, and various modifications are possible. In Embodiments 1 and 2, the first slit 12a and the second slit 13a were described as being arranged substantially orthogonally, but the present invention is not limited to substantially orthogonal arrangement. The first slit 12a and the second slit 13a can intersect at any angle as long as the second drain hole 4 can be formed by their intersection.

[0043] In Embodiment 1, it was explained that the first slit 12a is formed parallel to the length direction of the shoe 1 and the second slit 13a is formed parallel to the width direction of the shoe 1. However, the direction of the slits may be reversed. That is, the first slit 12a may be formed parallel to the width direction of the shoe 1 and the second slit 13a may be formed parallel to the length direction of the shoe 1.

[0044] In Embodiment 2, the first slit 22a and the elongated groove 23a were described as being arranged substantially orthogonally, but the present invention is not limited to substantially orthogonal arrangement. The first slit 22a and the elongated groove 23a can intersect at any angle as long as they can intersect to form the second drain hole 4a.

[0045] In Embodiment 3, the first slit 32a and the second slit 33a, and the second slit 33a and the third slit 34a were described as being arranged substantially orthogonally, but the present invention is not limited to substantially orthogonal arrangement. As long as the first slit 32a and the second slit 33a intersect to form the second drain hole 4b, and the second slit 33a and the third slit 34a intersect to form the third drain hole 4c, they may intersect at any angle.

[0046] In embodiments 2 and 3, it was explained that the second sole 24 can be formed from rubber material, but the material of the second sole 24 is not limited to rubber material and can be applied to a second sole formed from other materials such as felt fabric.

[0047] In embodiments 1 to 3, felt fabric and rubber were described as materials for the second sole 14, but the material is not limited to these and can be applied to various shoe soles used for shoes worn in or near water. [Explanation of Symbols]
