1. Upper
The upper is one of the main components of the shoe. For smooth shoes, it depends on whether they are soft and plump, and whether there is a loose surface phenomenon after pressing the vamp with your hand. For the upper suede shoes, attention should be paid to checking whether the fluff is short and uniform, and its color tone should be consistent.
2. 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 have flatly adhered to the inner sole, and there should be no hanging folds.
3. Outsole
From the appearance, the joint state of the periphery of the outsole should be closely bonded without gaps, and the bottom surface should be flat.
4. Heel
Whether it is a low heel or a high heel, the first thing to look at is whether it fits naturally with the shoe. For women's shoes with a half high heel or above, the following two points are more important: First, the heel should be firmly installed on the inner sole. Swing back and forth and left and right should not be shaken; the second is that the palm surface should not be smaller than the bottom surface of the heel.
