Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of casual shoes, in particular to a microfiber leather fold-resistant non-deformable casual shoe. BACKGROUND

[0002] Most casual shoes on the market currently use natural leather or synthetic leather as the upper material. Natural leather has good breathability and softness, but due to high cost and limited resources, it is difficult to popularize on a large scale. Synthetic leather, although relatively low in price, has obvious shortcomings in durability and environmental performance. In recent years, with the development of high polymer material science, microfiber leather as a new type of upper material has gradually attracted attention. Microfiber leather not only has an appearance and touch close to natural leather, but also has better wear resistance and tear resistance, so it has been widely used in the high-end shoe market.

[0003] In order to improve the durability and comfort of casual shoes, the existing technical means mainly include: using multi-layer composite materials to enhance the strength of the upper, such as coating a layer of PU film on the surface of synthetic leather to increase its wear resistance, adding shock-absorbing materials such as EVA foam material to the sole to improve wearing comfort, and improving the sewing process to reduce thread exposure and reduce the risk of wear. These means can improve the performance of casual shoes to some extent, but still have some obvious shortcomings. First, multi-layer composite materials increase the weight of the shoe, affecting portability. Second, the shock-absorbing effect of EVA foam material is limited and cannot meet the needs of high-intensity sports. Finally, although improving the sewing process can reduce thread exposure, it cannot completely avoid wear and tear.

[0004] In summary, the main defects of the existing technology are:

[0005] Multi-layer composite materials increase the weight of the shoe, reducing the overall portability of the shoe. The shock-absorbing effect of EVA foam material is limited and cannot meet the needs of high-intensity sports. Although improving the sewing process can reduce thread exposure, it cannot completely solve the problem of wear and tear. CONTENT OF THE INVENTION
