Description

Technical Field

[0001] This utility model relates to the field of footwear technology, and in particular to a breathable sole structure and shoe. Background Technology

[0002] Sweaty feet are caused by excessive secretion of sweat glands in the feet, especially in the hot summer when sweaty feet easily produce large amounts of sweat. If shoes are not breathable, the sweat cannot evaporate in time, which can easily lead to problems such as foot odor.

[0003] To address the breathability issue in shoes, some researchers have implemented techniques such as incorporating air cushions or valves into the sole to enhance ventilation. However, this has resulted in complex structures for breathable soles, requiring ample installation space and a certain thickness. These breathable structures are typically only suitable for athletic shoes with thicker soles, and are not applicable to thinner soles, such as those found in leather shoes. Utility Model Content

[0004] The purpose of this utility model is to address the deficiencies in the above-mentioned technology by providing a breathable sole structure and shoe. The breathable structure is simple, occupies little space, and is applicable to a wide range of shoe types.

[0005] The purpose of this utility model is achieved as follows:

[0006] This application provides a breathable shoe sole structure, including a shoe sole, wherein the shoe sole has a first air hole that penetrates the upper surface of the shoe sole and extends into the interior of the shoe sole, and a second air hole that penetrates the side of the shoe sole; wherein the first air hole and the second air hole are connected.

[0007] In the above design, the interconnected first and second air vents constitute the breathable structure of the sole. This structure is simple, requires minimal sole thickness, and is suitable for various footwear types, including leather shoes and boots. When the wearer is in motion, the airflow velocity at the outlet of the second air vent on the side of the sole is greater than the airflow velocity inside the sole. At this time, the internal pressure of the shoe is greater than the pressure at the outlet, creating a pressure difference. Under this pressure difference, the gas inside the shoe flows sequentially through the first and second air vents to the outside of the sole, enhancing breathability. Even when stationary, heat can still be dissipated from inside the shoe through the first and second air vents, facilitating perspiration and preventing sweaty feet.

[0008] In one possible implementation, the axis of the second vent is a straight line, a curve, a broken line, or a combination of one or more of these.

[0009] In one possible implementation, the axis of the second air hole is parallel to or at an angle to the width direction of the sole.

[0010] In one possible implementation, a shoe insole disposed above the sole is also included;

[0011] The insole is attached to the sole, and the insole is provided with a third air hole that communicates with the first air hole and the third air hole extends through the thickness direction of the insole.

[0012] In one possible implementation, the insole has a groove on the side away from the sole, and the third air hole is placed in the groove.

[0013] In one possible implementation, the groove includes a plurality of first grooves with lengths along a first direction and second grooves with lengths along a second direction;

[0014] The first groove intersects with the second groove to form a mesh structure;

[0015] The third pore is placed at a node of the grid structure.

[0016] In one possible implementation, a breathable fabric layer is provided over the groove.

[0017] A second aspect of this application provides a shoe comprising the breathable sole structure described in any of the preceding claims. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0027] To facilitate understanding of the breathable sole structure and shoe provided in this application embodiment, its application scenario will first be described. Due to work and daily life reasons, some people still need to wear leather shoes, sneakers, and other types of shoes in the hot summer. However, many shoe types have poor breathability, especially for people with sweaty feet. Poor breathability prevents sweat from being released, leading to problems such as stuffy and smelly feet. This application aims to improve the breathability of the sole, facilitating sweat wicking and heat dissipation from the feet.

[0028] Reference Figures 1-8 This application provides a breathable shoe sole structure, including a shoe sole 1, wherein the shoe sole 1 is provided with a first air hole 11 that penetrates the upper surface of the shoe sole 1 and extends into the interior of the shoe sole 1, and a second air hole 12 that penetrates the side surface 13 of the shoe sole; wherein the first air hole 11 and the second air hole 12 are connected.

[0029] It should be noted that, in this application, the upper surface of the sole 1 refers to the side of the sole 1 closest to the foot, and the side surface 13 of the sole refers to the surface that covers the thickness of the sole 1, that is, the surface between the upper and lower surfaces of the sole 1. The lower surface of the sole 1 refers to the surface in contact with the ground.

[0030] Specific reference Figure 5 , Figure 5 The first vent 11 and the second vent 12 are connected. The first vent 11 can be set perpendicular to the second vent 12 or at a certain angle.

[0031] Furthermore, the cross-sectional shape of the first vent 11 and the second vent 12 in this application can be various geometric shapes such as circular, square, oblong, and pentagonal. When applied to different types of shoes, the specific combination can be determined by referring to the shoe's shape, pattern, and applicable scenarios.

[0032] In this application, the second vent 12 penetrates the side 13 of the sole 1, wherein, as shown in the image... Figures 1-3 As shown, the second vent 12 is a through hole, penetrating both opposite or non-opposite sides of the sole 1. It can also be as follows... Figure 4 As shown, the second vent 12 penetrates one side of the sole 1. This is designed to connect the first vent 11 and the second vent 12 to form an air channel, allowing air inside the shoe to flow to the outside, thus ensuring good breathability. The specific location of the vent where the second vent 12 intersects with the side 13 of the sole 1 can be determined according to the style and type of the shoe, ensuring good breathability while maintaining an attractive appearance.

[0033] In the above design, the interconnected first vent 11 and second vent 12 constitute the breathable structure of the sole 1. This structure is simple, requires minimal thickness of the sole 1, and is suitable for various types of footwear, including leather shoes and boots. When the wearer is in motion, the airflow velocity at the outlet of the second vent 12 on the side 13 of the sole 1 is greater than the airflow velocity inside the sole 1. At this time, the internal pressure of the shoe is greater than the pressure at the outlet, creating a pressure difference. Under this pressure difference, the gas inside the shoe flows sequentially through the first vent 11 and the second vent 12 to the outside of the sole 1, enhancing breathability. Even when stationary, heat inside the shoe can still be dissipated through the first vent 11 and the second vent 12, facilitating sweat evaporation and preventing sweaty feet.

[0034] In addition to providing good breathability to the sole 1, the second vent 12 can also improve the elasticity of the sole 1, making it softer and thus enhancing the comfort of the shoe.

[0035] In one optional embodiment, the axis of the second vent 12 is a straight line, a curve, or a broken line, or a combination of one or more of these. (Refer to...) Figure 1 , Figure 3 The axis of the second vent 12 shown is a straight line; Figure 2 , Figure 4 The axis of the second air hole 12 is a broken line. That is to say, the direction of the second air hole 12 can be specifically set according to the shape and type of the shoe.

[0036] The axis of the second air hole 12 is parallel to or at a certain angle to the width direction of the sole 1. The width direction of the sole 1 is referenced... Figure 1 As shown, Figure 1 The axis of the second air hole 12 is parallel to the width direction of the sole 1. (Refer to...) Figure 3 , Figure 3 The axis of the second air vent 12 is at a certain angle to the width direction of the sole 1. Since the movement path of the shoe is generally perpendicular to the width direction of the sole 1 in most cases during walking, setting the axis of the second air vent 12 at a certain angle to the width direction of the sole 1 allows for better airflow during walking. The phrase "the axis of the second air vent 12 is at a certain angle to the width direction of the sole 1" in this application includes cases where the axis of the second air vent 12 is perpendicular or approximately perpendicular to the width direction of the sole 1.

[0037] In one alternative implementation, refer to Figures 6-8The shoe also includes an insole 2 disposed above the sole 1, the insole 2 being fitted to the sole 1. The insole 2 can float above the sole 1, or it can be fixed above the sole 1 by sewing, gluing, or other methods. The area above the sole 1 in this application refers to the side of the sole 1 that is away from the ground when worn. The insole 2 has a third air hole 21 communicating with the first air hole 11, the third air hole 21 extending through the thickness direction of the insole 2.

[0038] In this application, an insole 2 is provided above the sole 1. When the first air hole 11 is connected to the third air hole 21, and since the other side of the first air hole 11 is also connected to the second air hole 12, the third air hole 21, the first air hole 11, and the second air hole 12 are connected to each other, forming an air channel between the sole and the outside of the sole 1, thereby enhancing the breathability and heat dissipation of the sole.

[0039] In one optional embodiment, to further enhance the breathability of the sole 1, the insole 2 has a groove 22 on the side away from the sole 1, and the third air hole 21 is placed in the groove 22. At this time, the sole of the foot is in contact with the insole 2, and a gap is formed between the groove 22 and the sole, which facilitates the flow of gas in the groove 22 and improves the breathability of the shoe.

[0040] In one optional embodiment, the groove 22 includes multiple first grooves with lengths along a first direction and second grooves with lengths along a second direction. The first and second grooves intersect to form a grid structure, and the third air hole 21 is placed at a node of the grid structure. The first and second directions refer to any two directions that can intersect. Multiple grooves 22 with different directions form a grid structure on the surface of the insole 2, and the third air hole 21 is provided at the grid nodes, creating airflow between multiple areas of the sole, enhancing gas flow, and facilitating gas exit from the third air hole 21.

[0041] In one alternative embodiment, to enhance the aesthetics of the insole 2 and prevent dust accumulation in the groove 22 that is difficult to clean, a fabric layer is provided over the groove 22. The fabric layer is breathable to ensure the flow of gas and facilitate the evaporation and removal of sweat.

[0042] A second aspect of this application provides a shoe including the breathable sole 1 structure described in any of the preceding claims. Because the breathable sole 1 structure in this application is simple, the diameter of the second air hole 12 can be large or small, allowing the technical solution of this application to be applied to various shoe types without being affected by the thickness of the sole 1. If applied to athletic shoes with a relatively thick sole 1, the pore diameters of the first air hole 11 and the second air hole 12 can be appropriately increased to enhance gas flow. If the sole 1 is relatively thin, such as in leather shoes, the pore diameter of the second air hole 12 can be appropriately decreased.
