[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments.

[0025] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0026] As shown in Figure 1 - Figure 3 The present application provides a shoe structure with a composite sole 1, which comprises an insole layer 10, a cushion layer 20, a support layer 30 and an anti-skid layer 40 stacked in order from top to bottom. A plurality of first air holes 11 are formed in the insole layer 10, and the first air holes 11 are arranged in a curved manner. A plurality of second air holes 21 are formed in the cushion layer 20, and the second air holes 21 are arranged in a curved manner. When the insole layer 10 is connected to the cushion layer 20, the first air holes 11 communicate with the second air holes 21 to form air channels, and the air channels are arranged in a serpentine manner.

[0027] A plurality of air channels arranged in a serpentine manner are arranged between the upper and the cushion layer 20. These air channels are made of a flexible and air-permeable silicone material. The serpentine design greatly increases the length of the air channels and prolongs the residence time of air in the channels, allowing the air inside the shoe to exchange heat with the outside air more fully.

[0028] The serpentine air channels prolong the air flow path and increase the heat exchange time between the air inside the shoe and the outside air, effectively improving the air permeability of the shoe. When the user walks, the deformation of the sole promotes air flow, and fresh air from the outside can continuously enter the shoe, expelling moisture and heat, improving the hot and humid environment inside the shoe and improving the comfort of wearing.

[0029] The buffer layer 20 is made of a mixture of thermoplastic polyurethane (TPU) and silica gel, which improves elasticity and air permeability. The second air permeable hole 21 extends in a three-dimensional spiral curve, which not only bends in the plane but also undulates in the vertical direction, increasing the residence and exchange time of air in the buffer layer 20. When the insole layer 10 is connected with the buffer layer 20, the first air permeable hole 11 and the second air permeable hole 21 are connected through a special mortise and tenon structure, ensuring that the connection is tight and does not affect air circulation, so that the air permeable channel as a whole presents a complex serpentine spatial curve, greatly prolonging the air circulation path and enhancing the heat exchange effect.

[0030] Further, the inner wall of the air permeable channel is provided with a plurality of protrusions 13.

[0031] The inner wall of the channel is provided with a plurality of small protrusions 13, which further disturb the airflow, enhance the air mixing effect, and improve the ventilation efficiency. Air collides with the protrusions 13 during flow, changes the flow direction, so that the air in different areas of the shoe can be more fully exchanged, making the air permeation effect more uniform and reducing the local hot and humid conditions.

[0032] The protrusions 13 on the inner wall of the air permeable channel are divided into two types. One is a hemispherical protrusion 13 with a diameter of 0.2-0.3 mm, uniformly distributed on the inner wall of the channel, mainly used to disturb the airflow direction and enhance air mixing. The other is a prismatic protrusion 13 with a height of 0.3-0.4 mm, arranged in groups along specific areas of the channel (such as turning places and areas with weaker airflow), each group containing 3-5 prismatic protrusions 13. The sharp edges of the prismatic protrusions 13 can more strongly cut the airflow, generating local turbulence, further improving the ventilation efficiency, and making the air in different areas of the shoe more fully mixed and exchanged.

[0033] Further, the insole layer 10 is provided with a mesh fabric corresponding to the surface of the opening of the first air permeable hole 11.

[0034] The mesh fabric can block dust, sand and other foreign matter from entering the shoe, while not affecting the air circulation efficiency. It ensures the cleanliness of the shoe, avoids the entry of foreign matter into the foot, causes discomfort or damage, maintains the air permeability, and improves the practicality and hygiene of the shoe.

[0035] The insole layer 10 is provided with three layers of composite mesh fabric corresponding to the surface of the opening of the first air permeable hole 11. The outermost layer is a high-strength nylon mesh with a mesh diameter of 0.5-0.8 mm, which is used to block larger foreign matter; the middle layer is an activated carbon fiber mesh, which can adsorb odors and some harmful gases, purifying the air entering the shoe; the innermost layer is a hydrophilic polyester fiber mesh with a mesh diameter of 0.3-0.5 mm, which can prevent small particles from entering while also assisting in absorbing foot sweat, ensuring smooth air circulation while maintaining cleanliness and hygiene in the shoe.

[0036] Further, as shown in Figure 4 , Figure 5 , the support layer 30 is provided with a plurality of third air vents 31, one end of the third air vents 31 is communicated with the second air vents 21, and the other end is communicated with the edge of the support layer 30, and the third air vents 31 are arranged in a spiral shape.

[0037] The spiral third air vents 31 increase the channel surface area, and when the sole is deformed under force, the space change of the spiral structure can produce a pumping effect, accelerating air flow, and discharging the moisture in the shoe through the edge of the support layer 30, further enhancing the overall air permeability effect.

[0038] The support layer 30 is made of carbon fiber reinforced polyurethane foam material to improve the support strength and stability. The third air vents 31 are designed as a double helix structure, and the inner helix and the outer helix are connected by a plurality of transverse communication holes.

[0039] Further, the anti-skid layer 40 is provided with a plurality of fourth air vents 41, one end of the fourth air vents 41 is communicated with the third air vents 31, and the other end is communicated with the edge of the support layer 30, and the fourth air vents 41 are arranged in a spiral shape.

[0040] The fourth air vents 41 cooperate with the third air vents 31 to form a continuous air permeation path, allowing the moisture in the shoe to be discharged from the insole layer 10 through the buffer layer 20, the support layer 30, and finally through the anti-skid layer 40. Further improve the air permeation system of the entire sole, ensure the integrity and efficiency of the air permeation effect.

[0041] The anti-skid layer 40 is made of a composite material of nitrile rubber and natural rubber, which improves the wear resistance while ensuring the anti-skid performance. The fourth air vents 41 are combined with the anti-skid lines on the surface of the anti-skid layer 40, and part of the anti-skid lines are designed as a hollow structure and are communicated with the fourth air vents 41.

[0042] Further, the hole wall of the third air vent 31 is coated with a catalyst coating.

[0043] The catalyst coating can decompose odor molecules in the shoe, improve the air quality in the shoe, and remove odors while discharging moisture and heat, providing a more comfortable wearing environment for the user and improving the use experience of the shoe.

[0044] The catalyst coating coated on the hole wall of the third air vent 31 is a mixed coating of nano titanium dioxide and activated carbon. Nano titanium dioxide can decompose organic odor molecules and harmful bacteria in the shoe under light conditions, playing a role in air purification and antibacterial; activated carbon uses its rich pore structure to adsorb odors and moisture, improving the adsorption capacity of the catalyst coating.

[0045] Further, the material of the insole layer 10 is polyester fiber.

[0046] The insole layer 10 directly contacts the foot and is made of a fiber material with strong hydrophilicity and air permeability, such as specially treated polyester fiber, which has a surface covered with tiny pores that can quickly absorb foot sweat and transfer the sweat to the lower layer.

[0047] The insole layer 10 is made of polyester fiber modified by nano-silver ions. The nano-silver ions are uniformly distributed inside the polyester fiber, not only enhancing the antibacterial properties of the polyester fiber, effectively inhibiting bacterial growth and preventing foot odor, but also improving the hydrophilicity and air permeability of the fiber.

[0048] Further, the material of the insole layer 10 is polyester fiber.

[0049] The insole layer 10 directly contacts the foot and is made of a fiber material with strong hydrophilicity and air permeability, such as specially treated polyester fiber, which has a surface covered with tiny pores that can quickly absorb foot sweat and transfer the sweat to the lower layer.

[0050] The support layer 30 is made of high-density polyurethane foam material and is designed according to the curve of the human foot, providing good support for the foot, distributing the pressure on the sole and reducing the impact on the joints during walking.

[0051] The insole layer 10 directly contacts the foot and is made of a fiber material with strong hydrophilicity and air permeability, such as specially treated polyester fiber, which has a surface covered with tiny pores that can quickly absorb foot sweat and transfer the sweat to the lower layer.

[0052] Further, the material of the insole layer 10 is polyester fiber.

[0053] The insole layer 10 directly contacts the foot and is made of a fiber material with strong hydrophilicity and air permeability, such as specially treated polyester fiber, which has a surface covered with tiny pores that can quickly absorb foot sweat and transfer the sweat to the lower layer.

[0054] The anti-skid layer 40 is made of rubber composite material containing microcapsule repairing agent. The microcapsule repairing agent is evenly dispersed in the rubber. When the surface of the anti-skid layer 40 appears micro cracks due to abrasion, the microcapsule breaks to release the repairing agent to fill the cracks and restore the integrity and anti-skid performance of the anti-skid layer 40. The anti-skid lines are designed in a bionic way to imitate the sucker structure of gecko's footpads, and a plurality of micro convexes 13 are arranged on the surface of the lines. The top of each convex 13 is hemispherical, and the diameter is 0.1-0.2 mm to increase the friction with the ground. Meanwhile, glass fiber reinforcing material is added in the anti-skid layer 40 to enhance the wear resistance and tear resistance of the rubber, so that the anti-skid layer 40 can maintain good anti-skid and wear resistance effect for a long time while ensuring air permeability.
