To identify the quality of shoes, we need to focus on both appearance and internal indicators. Since the internal indicators often need to rely on testing instruments, for a consumer, it is more practical to identify the quality of shoes from the appearance.
From the insole
Usually men's shoes use the rear half of the insole pad or the heel pad. Women's shoes with full padding covering the insole. The insole has the function of keeping the insole clean and covering the unevenness of the insole to improve the foot feeling. Therefore, the insole should have good absorption and moisture removal. In terms of workmanship, the insole should be flatly adhered to the inner sole, and there should be no hanging folds.
