DETAILED DESCRIPTION

[0027] The following is a detailed description of embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0028] References in this specification to "one embodiment" or "an example" or "an example" mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment of the present patent disclosure. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0029] This embodiment provides a sandal, such as Figures 1 to 5 As shown, the shoe comprises a sole 11, an upper 12 and an insole 16. The insole 16 is arranged on the sole 11, the bottom of the upper 12 is arranged at the edge area of ​​the sole 11, and the upper 12 and the insole 16 are on the same side. A plurality of drainage grooves 11a are formed on the side of the sole 11 facing the insole 16. The plurality of drainage grooves 11a are spaced apart along the length direction of the sole 11, and the drainage grooves 11a penetrate the sole 11 along the width direction of the sole 11. The toe portion 111, the middle portion 112, and the heel portion 113 of the sole 11 are all formed with drainage grooves 11a. A plurality of drainage holes 16a are formed at positions corresponding to the drainage grooves 11a on the insole 16. The drainage holes 16a penetrate the insole 16 along the thickness direction, and the plurality of drainage holes 16a are respectively connected to the drainage grooves 11a at corresponding positions.

[0030] By providing a plurality of drainage holes 16a on the insole 16 along the thickness direction of the insole 16, and providing a plurality of drainage grooves 11a along the width direction of the sole 11, the drainage holes 16a are connected with the drainage grooves 11a at the corresponding positions, when water enters the shoe, the water flows downward through the drainage holes 16a, and after reaching the drainage grooves 11a, the water is discharged from both sides of the shoe along the drainage grooves 11a. In this way, while being able to drain water, since the sole 11 is not provided with a through hole along the thickness direction of the sole 11, the sewage on the ground cannot enter the shoe through the sole 11. The method of providing the drainage holes 16a on the upper 12 can also prevent the sewage on the ground from entering the shoe, but the water in the low-lying part of the shoe cannot be discharged during drainage, resulting in water accumulation in the space in the shoe for a long time, which is more likely to breed bacteria. The sandals of this embodiment, by providing the longitudinal drainage holes 16a and the transverse drainage grooves 11a, can make the water in the shoe be discharged smoothly, and can also prevent the sewage on the ground from entering the shoe from the drainage holes 16a. In addition, drainage grooves 11a are provided at the toe portion 111, the middle portion 112, and the heel portion 113 of the sole 11 to prevent sewage from being unable to be discharged in local low-lying areas. For example, if the drainage groove 11a is provided only at the toe portion 111, and the middle portion 112 is slightly higher than the heel portion 113, it is difficult for sewage at the heel to flow to the toe portion 111, that is, it is difficult to flow out through the drainage hole 16a at the toe portion 111 and the drainage groove 11a.

[0031] Alternatively, if Figure 1 and Figure 5As shown, the sandal further includes a protective edge 14, which is arranged around the periphery of the sole 11, and the top of the protective edge 14 protrudes from the top surface of the sole 11. The connection between the upper 12 and the sole 11 is located on the inner side of the protective edge 14. The protective edge 14 is formed with a plurality of side drainage holes 14a corresponding to the drainage grooves 11a, and the side drainage holes 14a are connected to the drainage grooves 11a.

[0032] By providing the protective edge 14, and the top of the protective edge 14 protruding from the top surface of the sole 11, the user's foot is prevented from slipping out of the hole in front of the shoe when wearing the shoe, thereby protecting the user's toes and reducing the possibility of spraining the ankle. The part of the protective edge 14 protruding from the top surface of the sole 11 fits the upper 12. At the same time, the protective edge 14 is adaptively provided with a side drainage hole 14a corresponding to the drainage groove 11a to prevent the water in the drainage groove 11a from being unable to be discharged.

[0033] In the present invention, there is no special limitation on the materials of the sole 11 and the protective edge 14. In order to increase comfort and improve the anti-collision effect, the sole 11 and the protective edge 14 are optionally made of rubber material, such as CPE (Chlorinated Polyethylene). When the user accidentally kicks his foot, the rubber protective edge 14 has a certain buffering effect on the toes, thereby reducing the degree of damage to the toes. Preferably, the protective edge 14 is integrally formed with the sole 11, thereby improving the firmness of the connection between the protective edge 14 and the sole 11, reducing the processing steps, and reducing the processing cost.

[0034] In order to improve the comfort of use, in an optional embodiment, as Figure 3 As shown, the insole 16 includes an insole body 161 and a support pad 162. The insole body 161 is arranged on the sole 11. The insole body 161 includes a main support area and an auxiliary support area. The auxiliary support area is located in the middle of the insole body 161. The support pad 162 is arranged in the auxiliary support area. A plurality of drainage holes 16a are formed on the main support area.

[0035] Specifically, the area where the insole body 161 corresponds to the arch of the foot is the auxiliary support area, and a support pad 162 is provided on the auxiliary support area to support the arch of the user's foot and improve comfort. It can be understood that the support pad 162 protrudes from the surface of the insole body 161, and is not easy to accumulate water. The drainage hole 16a corresponding to the drainage groove 11a is not provided at the support pad 162.

[0036] Alternatively, if Figure 3 and Figure 5 As shown, each drainage groove 11a located at the toe portion 111 and the heel portion 113 is communicated with at least two drainage holes 16a, and each drainage groove 11a located at the middle portion 112 is communicated with at least one drainage hole 16a.

[0037] Since the width of the area corresponding to the toe portion 111 and the heel portion 113 of the insole body 161 is generally greater than the width of the area corresponding to the middle portion 112 of the sole 11, the number of drainage holes 16a provided in the area corresponding to the toe portion 111 and the heel portion 113 of the insole body 161 is greater than the number of drainage holes 16a provided in the area corresponding to the middle portion 112 of the insole body 161. Since the number of drainage holes 16a provided in the area corresponding to the toe portion 111 and the heel portion 113 of the insole body 161 is greater than the number of drainage holes 16a provided in the area corresponding to the middle portion 112 of the sole 11. In order to ensure the drainage effect, along the length direction of the drainage groove 11a, at least two drainage holes 16a are provided in the area corresponding to the toe portion 111 and the heel portion 113 of the insole body 161, and at least one drainage hole 16a is provided in the area corresponding to the middle portion 112. That is, each drainage groove 11a of the toe portion 111 and the heel portion 113 is communicated with at least two drainage holes 16a, and the drainage groove 11a of the middle portion 112 is communicated with at least one drainage hole 16a.

[0038] In order to prevent sewage from flowing into the space between the insole 16 and the sole 11, in an optional embodiment, as Figure 4 As shown, the dimension of the drainage hole 16a along the width direction of the drainage groove 11a is less than or equal to the width of the drainage groove 11a.

[0039] By setting the size of the drainage hole 16a along the width direction of the drainage groove 11a to be less than or equal to the width of the drainage groove 11a, water in the shoe is prevented from flowing into the space between the insole 16 and the sole 11 when flowing out through the drainage hole 16a, thereby reducing the growth of bacteria caused by sewage remaining between the insole 16 and the sole 11.

[0040] Alternatively, if Figure 1 As shown, the upper 12 includes a connecting portion, a first fixing portion 121, a second fixing portion (not shown in the figure) and an inner heel strap 13. The connecting portion is arranged between the first fixing portion 121 and the second fixing portion, one end of the first fixing portion 121 away from the connecting portion is connected to the first side of the sole 11, and one end of the second fixing portion away from the connecting portion is connected to the second side of the sole 11, the first side and the second side are opposite, and the first fixing portion 121 and the second fixing portion are both formed with a plurality of ventilation holes 12a. The connecting portion is connected to a side of the toe portion 111 away from the heel portion 113. The inner heel strap 13 is connected between the first fixing portion 121 and the second fixing portion, and the inner heel strap 13, the first fixing portion 121, the second fixing portion and the connecting portion enclose a top opening of the sandal.

[0041] Among them, ventilation holes 12a are provided in the first fixing part 121 and the second fixing part to increase the cool feeling of wearing shoes. At the same time, the ventilation holes 12a can also be used as quick drainage holes. For example, when stepping on a deeper puddle, most of the sewage in the shoes can be quickly discharged through the ventilation holes 12a.

[0042] In an alternative embodiment, if Figure 1 As shown, the connection part includes a connection part body 122 and a shoe tongue 123. The connection part body 122 is arranged between the first fixing part 121 and the second fixing part. One end of the connection part body 122 is connected to the side of the toe part 111 away from the heel part 113, and the other end of the connection part body 122 is connected to the shoe tongue 123. The sandal also includes a shoelace 17. The shoelace 17 and the shoe tongue 123 are located at the same end of the connection part body 122. The shoelace 17 is used to connect between the first fixing part 121 and the second fixing part.

[0043] Through the cooperation of the tongue 123, the first fixing part 121, the second fixing part and the shoelace 17, when the user needs to put on the shoes, the shoelace 17 is untied, and the first fixing part 121, the second fixing part and the tongue 123 are relatively unfolded, so that the top opening of the sandal is enlarged, making it easier for the user to put on the shoes and reducing damage to the upper 12 and the inner heel strap 13.

[0044] Optionally, the sandals further include Velcro 18, which is connected between the first fixing portion 121 and the second fixing portion, thereby reducing the possibility of the sandals being separated from the foot after the user puts on the sandals.

[0045] In order to improve the protection effect, optionally, the sandal further includes an outer heel strap 15 , both ends of which are connected to the protection edge 14 , and the outer heel strap 15 is used to fit with the outer surface of the inner heel strap 13 .

[0046] By arranging the outer heel strap 15 at the heel portion 113 of the sole 11, both ends of the outer heel strap 15 are connected to the protective edge 14, which plays a certain supporting and protective role for the user's heel. Preferably, the material of the outer heel strap 15 is rubber.

[0047] In an optional embodiment, the outer heel strap 15 includes an outer heel strap body 151 and a third fixing portion 152, the two ends of the outer heel strap body 151 are respectively connected to the two ends of the third fixing portion 152, the third fixing portion 152 is connected to the outer surface of the protective edge 14 located at the heel portion 113 of the shoe, and the outer heel strap body 151 is used to fit with the outer surface of the inner heel strap 13.

[0048] Specifically, the third fixing portion 152 and the outer heel strap body 151 are integrally formed, and the outer heel strap body 151 is connected to the protective edge 14 via the third fixing portion 152. Since the connection area between the outer heel strap body 151 and the protective edge 14 is increased, the connection firmness between the outer heel strap body 151 and the protective edge 14 is improved.

[0049] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments.
