Pay attention to the following points when buying shoes:
1, check the adhesion of shoes. Especially between the sole and the shoe surface. There are generally three ways to bond soles and uppers: one is to sew them together with thread; The second is to stick together with super glue. Third, sewing and gluing are used together. No matter what method is used, the sole and the upper should be aligned. Also carefully observe the position and state of the heel, toe and foot curves of shoes, as well as the relationship between these parts.
2. Check the processing quality of the inner pad and insole in direct contact with the sole by hand. If there are wrinkles and bulges on the inside of the shoes, it means that the shoes are definitely uncomfortable. If the joints and interfaces are rough, the knots will rub the feet; Nailing shoes is not good, sometimes the insole will be pushed up, and the shoes will be uncomfortable to wear.
3. Press the toe with your fingers to check its elasticity and leather thickness. If it is too thin, it will collapse immediately. This kind of shoes is not good. Choose shoes with certain elasticity.
4. Check the bending state of the sole, especially the bending state of the corresponding part of the toe root. This is the life of shoes, so be careful.
