To identify the quality of shoes, we need to look at both the appearance and internal indicators. Since internal indicators often require the help of testing instruments, it is more practical for a consumer to identify the quality of shoes from the appearance. From the appearance, the quality of shoes is mainly identified by the quality of the materials (including uppers, soles, and linings) and the workmanship. The size can be measured, and the craftsmanship is mainly based on visual inspection, hand touch, pinching, and pushing.
Insole
On the one hand, the material of the insole should be leather. On the other hand, the waist should be pressed hard by hand, which is equivalent to the part of the instep when wearing shoes. It is better if it does not move at all. Under the action of this force, if the edge of the shoe is deformed, it means that the quality of the shoe is problematic.
