In the field of shoe manufacturing, the durability of finished shoes (including bending resistance, wear resistance, upper surface pulling resistance and the like) is an important index for detecting the quality of the finished shoes. In the prior art, the fatigue test of the finished shoes is usually realized by real person fitting, the method has the problems of long fitting period, difficult guarantee of timeliness and influence on product marketing, and in addition, the problem of larger difference of test results caused by different fitting personnel exists.

Therefore, the industry standard for testing the durability of the shoes by adopting the testing equipment appears at home and abroad, however, the existing testing equipment, whether domestic or foreign, has the following defects: firstly, a shoe tree for wearing shoes is made of hard PVC materials, the surface of the shoe tree is hard, so that good bending and extruding effects cannot be formed, and the simulation effect on walking or running and other behaviors of a human body is not good enough; secondly, in order to realize bending, shoe trees used by the existing testing equipment have the condition that a larger groove needs to be formed on the instep, so that the plumpness of the whole shoe tree is not enough and the whole shoe tree does not have a complete toe part and an ankle part, therefore, the phenomena of extrusion and pulling of different positions of the upper surface under the actions of walking or running and the like of a person cannot be accurately simulated during testing, and the durability testing structure of the shoe cannot be accurately obtained; third, when the existing test equipment is used for testing, the toe cap is usually pressed, the heel is free, and the degree of freedom of the shoe corresponding to the half sole part of the foot of a human body is insufficient, so that the stress condition of the shoe when being trampled can not be well reflected.
