Problems solved by technology

[0006] 1. The wear resistance is poor. When used as a climbing shoe sole material, it is easy to wear and tear, resulting in damage and poor durability;
[0007] 2. After foaming, the tensile strength is greatly reduced, the mechanical properties are poor, and the comprehensive performance is poor; or the degree of foaming is low, and it does not have good portability;
[0008] 3. Poor anti-slip effect
