Abstract
Description
Technical Field
[0001] This application relates to the field of sports shoe equipment, specifically a hollow-soled sports shoe. Background Technology
[0002] Shoes are a necessity in people's daily lives. Especially during running, the various performance characteristics of shoes can affect the wearer's experience and even the effect of the exercise. As people's living standards improve, they are paying more and more attention to leisure, fitness and sports, and sportswear is also widely favored. For sports enthusiasts, especially young people, running shoes are often worn.
[0003] A shock-absorbing sports shoe is disclosed in utility model patent CN218960162U. Its structure includes an upper with an opening at the top and a breathable component at the bottom. The breathable component includes a sole with a groove at the top. A perforated pad is fixed to the bottom of the inner wall of the groove, forming an annular groove between the perforated pad and the groove. A cover layer is fixed to the outer edge of the top of the sole and adhered to the outside of the upper. An air channel is formed between the upper and the cover layer, connecting the annular groove and the outside of the upper. This utility model has the following advantages: by applying the sole component, when the user steps on the perforated pad, the air inside the upper and the perforated pad is compressed into the annular groove. The air then passes through the cover layer attached to the outside of the upper and is expelled upwards along the upper through the air channel, raising the air outlet position and thus increasing the possibility of water entering the shoe. Furthermore, the cover layer reconnects to the upper for improved stability, resulting in good overall breathability and comfort.
[0004] The athletic shoe features an upper with a sole at the bottom and a perforated padding layer at the top. During exercise, the perforated padding layer on the sole provides shock absorption and cushioning. However, relying solely on the perforated padding layer for cushioning can lead to collapse during prolonged wear, resulting in poor cushioning and reduced shock absorption. Utility Model Content
[0005] In view of the problem of poor cushioning effect in the existing technology, this utility model provides a hollow-out sole sports shoe.
[0006] Therefore, the specific technical solution adopted by this utility model is as follows:
[0007] This utility model provides a hollow-out sole sports shoe, including a sole, an upper fixedly mounted on the top of the sole, ventilation holes provided on the upper, and a hollow groove penetrating the sole on the back side of the sole. An elastic component is provided in the hollow groove, the elastic component including an air bladder and a spring. The upper and lower ends of the air bladder abut against the inner wall of the hollow groove, and an inflation chamber is provided in the air bladder. The spring is vertically mounted in the inflation chamber, and the two ends of the spring are respectively connected to the top and bottom of the inflation chamber.
[0008] Preferably, the shoe upper has a protective pad on the inside of the opening. The protective pad at the opening of the shoe upper protects the heel and prevents the heel from directly contacting and squeezing the rear of the shoe upper during prolonged strenuous exercise, thus ensuring the wearer's comfort and safety.
[0009] Preferably, the protective pad is connected and fixed to the shoe upper by Velcro, which allows the wearer to easily remove the protective pad and install a new one when it is damaged.

[0012] Preferably, it also includes an insole, which is set at the bottom of the sole and has a protrusion at the top of the front end. By setting an insole with a protrusion on the sole, the stability of the wearer is increased and the foot is reduced from sliding on the insole.
[0013] Preferably, the front side of the top of the shoe sole is provided with multiple sets of airflow channels. The airflow channels can guide the airflow generated at the contact surface between the foot and the shoe sole during exercise, so that the airflow at the bottom can be transferred to the top and discharged, thereby improving the wearer's comfort.
[0014] The advantages of adopting the above technical solution are:
[0015] This invention features a sole with an upper fixedly mounted on top. The upper has ventilation holes, and the back of the sole has a through-hole groove. An elastic component, including an air bladder and a spring, is installed within the groove. The air bladder's upper and lower ends abut against the inner wall of the groove. An inflation chamber is located within the air bladder, and the spring is vertically positioned within it, with its two ends connected to the top and bottom of the chamber, respectively. By incorporating the through-hole groove, air bladder, and spring in the sole, this device allows for shock absorption during exercise, ensuring the wearer's comfort. Furthermore, the air bladder and spring provide support and compression to the sole during deformation, extending the lifespan of the athletic shoe. Attached Figure Description

[0031] When the wearer exercises, the ventilation holes 201 on the upper 2 allow external airflow to circulate and exchange with the air inside the shoe, keeping the air inside the shoe clean and ensuring foot comfort. Furthermore, during walking, the hollowed-out groove 101 located below the heel on the sole 1 and the airbag 3 within the hollowed-out groove 101 allow the airbag 3 to cushion deformation caused by compression of the sole 1, thus providing shock absorption for the wearer. The elasticity of the airbag 3 further helps to reduce the impact of the deformation. It can promote the sole 1 to return to its original shape after deformation, thus improving the service life of the sports shoe. The air bladder 3 is also equipped with a spring 4 inside the inflation chamber. The spring 4 is vertically set in the inflation chamber. By setting the spring 4, the sole 1 is further supported, ensuring that the sole 1 recovers quickly after deformation. The dual shock absorption of the air bladder 3 and spring 4 improves the wearer's comfort and shock absorption effect. The spring 4 is set in the inflation chamber, which also prevents external rainwater from entering the hollow groove 101 and contacting the spring 4 in rainy weather, thus ensuring the service life of the spring 4.
