Description

Technical Field

[0001] The utility model relates to the technical field of breathable shoes, in particular to a breathable device and a sole and a shoe applied thereto. Background Art

[0002] Shoes consist of an upper and a sole, protecting the foot from sharp objects while walking. Traditional shoes utilize an upper for improved breathability, while the sole is made of insulating materials. This lacks breathability, hindering the drainage of sweat from the soles of the feet, fostering the growth of fungi and mold, and leading to athlete's foot, which harms the wearer's foot health.

[0003] In order to enhance the air permeability, shoes on the market have been provided with air vents on the side of the soles, so that air can be sucked in or discharged through the soles, thereby enhancing the air circulation efficiency between the shoes and the outside world. For example, with reference to the Chinese utility model patent CN219939844U, a kind of air-permeable sole and shoes including the sole are disclosed, comprising a sole body, a shoe groove with an upper opening is provided on the sole body, a shoe groove bottom wall is provided with a supporting edge and a supporting beam, the supporting edge outer wall is connected to the shoe groove inner wall, a body is further provided with a plurality of air vents running through the supporting edge, and an insole adopts a breathable insole, which can ensure its good air permeability while achieving a certain waterproof effect. However, the waterproof and dustproof performance of such shoes is very poor. After walking on a road with more dust on the bottom for a period of time, the small air vents are easily blocked by accumulated dust, the air permeability of the sole is greatly reduced, and water on the road surface easily enters the sole through the air vents, resulting in poor waterproof effect and poor wearing experience.
