Abstract
Description
Technical Field
[0001] This utility model relates to the field of casual shoe technology, and in particular to a highly durable and breathable casual shoe. Background Technology
[0002] Shoes are an indispensable necessity in daily life. Due to different functions and styles, there are all kinds of shoes on the market. However, no matter how the appearance of shoes changes, the most important thing is to wear them comfortably and provide enough protection for the feet.
[0003] For example, the authorized announcement number "CN220631222U" is named "Breathable Adjustable Casual Shoes". When the windproof cloth is normally laid out, it can effectively block the airflow between the inside and outside of the shoe, improving the warmth of the casual shoes for the feet. By controlling the components, the windproof cloth is rolled up, exposing the breathable channels of the composite mesh fabric that were originally covered by the windproof cloth, so that the breathability of the casual shoes gradually increases, thereby achieving the adjustment of the breathability of the casual shoes.
[0004] The above-mentioned and existing technologies have the following defects: the entire sole of the casual shoe is solid, resulting in poor breathability of the entire sole; at the same time, the sole of the casual shoe does not take wear-resistant and flexural-resistant measures, resulting in poor wear resistance and flexural-resistant properties. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly durable and breathable casual shoe.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A highly durable and breathable casual shoe is designed, comprising a sole and an upper. The sole is composed of a first sole and a second sole bonded together. An insole assembly is provided on the upper surface of the second sole. An installation groove is formed on the upper surface of the first sole, and the second sole is disposed inside the installation groove. Multiple positioning grooves are formed circumferentially on the inner side wall of the installation groove. Multiple positioning blocks, corresponding one-to-one with the positioning grooves, are formed circumferentially on the circumferential surface of the second sole. The positioning blocks extend into the positioning grooves. An insertion groove is formed on the lower inner wall of the installation groove. An insertion block, matching the insertion groove, is integrally formed on the lower surface of the second sole and extends into the insertion groove. Multiple first ventilation holes are formed on the front and rear parts of the lower surface of the first sole. The lower cross-section of the first ventilation hole is frustoconical. A second ventilation hole is formed on the surface of the second sole and the insertion block, and the second ventilation hole communicates with the first ventilation hole. A flexural and abrasion-resistant device is provided on the front and rear parts of the lower surface of the first sole.
[0008] Preferably, the flexural and abrasion-resistant device includes multiple abrasion-resistant rings, all of which are disposed outside the first ventilation hole. The multiple second ventilation holes are provided with longitudinal abrasion-resistant strips on both the left and right sides, and transverse abrasion-resistant strips on both the front and rear sides of the second ventilation holes. Multiple TPU elements embedded in the first sole are provided between two adjacent transverse abrasion-resistant strips.
[0009] Preferably, the lower surface of the first shoe sole is provided with a plurality of V-shaped anti-slip blocks, and the openings of the plurality of V-shaped anti-slip blocks all face backward.
[0010] Preferably, the inner wall of the first vent hole is provided with a protective mesh.
[0011] Preferably, a waterproof and breathable membrane is adhesively bonded between the lower surface of the insertion block and the lower inner wall of the insertion groove.
[0012] Preferably, the insole assembly includes an insole body made of sponge material. The surface of the insole body has a plurality of third ventilation holes that correspond one-to-one with the second ventilation holes. The upper surface of the second sole has a plurality of snap-fit grooves, and the lower surface of the insole body has a plurality of snap-fit blocks that correspond one-to-one with the snap-fit grooves. The snap-fit blocks extend into the snap-fit grooves.
[0013] Preferably, the second vent hole is arranged at an angle.
[0014] The present invention proposes a highly durable and breathable casual shoe with the following advantages: The durable and abrasion-resistant device, through multiple longitudinal and transverse abrasion-resistant strips, increases the shoe's abrasion resistance. Simultaneously, the abrasion-resistant ring prevents wear on the edges of the first ventilation hole. The TPU element further enhances the shoe's tensile and flexural strength. In summary, the sole of this casual shoe exhibits excellent abrasion and flexural resistance. Furthermore, the sole is not solid, being glued together from a first and second sole. The first and second ventilation holes ensure good breathability of the second sole, preventing sweat from evaporating easily and improving the shoe's comfort. Attached Figure Description
