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.
Insoles
Generally, men's shoes use the back half of the insole or the heel pad. Women's shoes use the full pad covering the insole. The insole has the function of keeping the insole clean and covering the unevenness of the insole to improve the foot feel. Therefore, the insole should have good moisture absorption and moisture-wicking properties. In terms of workmanship, the insole should be flatly adhered to the insole, and there should be no suspended wrinkles.
