Narrowly speaking, it only refers to the outsole. Generally, the common characteristics of sole materials should include 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 should cooperate with the midsole to have a braking effect when walking and changing feet so as not to slip and be easy to stop. There are many types of sole materials, which can be divided into two categories: natural sole materials and synthetic sole materials. Natural sole materials include natural sole leather, bamboo, wood, etc., and synthetic sole materials include rubber, plastic, rubber-plastic composite materials, regenerated leather, elastic cardboard, etc.;

[0003] During the production process of the sole, it is necessary to conduct abrasion experiments on the sole, and at this time, an abrasion testing machine is required.

Then, since the fixing clamps are installed on both sides of the base, there are certain limitations. It cannot be adjusted according to the size and placement position of the sole sample, so it cannot clamp and fix sole samples of different sizes. Therefore, it cannot meet the fixing requirements of different sole samples, which is not conducive to the abrasion test of sole samples, thus reducing the applicability of the equipment.
