The injection shoe factory feels that the quality of the shoes needs to be judged from two aspects: 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.

　　1. Upper (Shoe Upper)

　　The injection shoe factory believes that the upper is one of the main components of the shoe.

　　2. insole

　　The injection shoe factory found that the usual men's shoes use the insole back half 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.

　　3. outsole

　　The injection shoe factory feels that from the outside, the joint state of the outer sole 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.

　　5. Insole

　　The injection shoe factory believes that on the one hand, looking at the material of the insole, it is best to be genuine leather. On the other hand, it is better to press the waist with your hand, which is equivalent to the part of the instep when wearing shoes.

　　6. stability

　　The injection shoe factory reminds that when the shoes are placed on a flat surface, the shoes should be stationary immediately. Such shoes have good stability, which is also one of the basic conditions for high-quality shoes.
