Technical Field

[0001] The utility model relates to the field of shoe soles, in particular to a lightweight, wear-resistant PU low-density shoe sole. Background Art

[0002] The structure of the sole is quite complex. In a broad sense, it can include all the materials that make up the sole, such as the outsole, midsole and heel. In a narrow sense, it only refers to the outsole. The common characteristics of general sole materials should be wear resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, good elasticity, easy to fit the foot shape, not easy to deform after shaping, heat preservation, easy to absorb moisture, etc. At the same time, it must be matched with the midsole to have a braking effect when changing feet while walking so as not to slip and easy to stop. There are many types of sole materials, which can be divided into two types: natural sole materials and synthetic sole materials.

[0003] However, the existing soles still have some shortcomings and areas for improvement during actual use. The existing soles are often light but have poor anti-slip properties when worn, or are anti-slip but have a certain weight, and are not comfortable enough. At the same time, the existing soles are easily reduced in friction and anti-slip properties due to friction during long-term wear, which affects the subsequent wearing effect and reduces the service life of the entire shoe. Therefore, technicians in this field provide a lightweight, wear-resistant PU low-density sole to solve the problems raised in the above background technology. Utility Model Content
