How to distinguish real leather shoes?

Real leather refers to natural leather, which is processed from animal skin. Fake leather refers to synthetic leather or other leather like products, which are actually synthesized from basic chemical raw materials. The structure of natural leather is very complex. It is very difficult or even impossible to make it by hand. Sometimes fake leather can be confused with the real leather. It is difficult to distinguish the real leather from the fake leather by the following methods: for leather finished products, it is difficult to distinguish the real leather from the fake leather, especially for leather products with small area, compact structure and invisible inside. The identification method for this kind of products is as follows: first look at the appearance, the leather with uniform texture, no damage, no coarse grain and no defect may be artificial leather;

There are some differences in the texture of leather, especially in the joint between the main part and the secondary part of leather products. The distribution and shape of pores were observed carefully; The natural leather has many deep holes, which is not suitable for bottoming and slightly inclined; However, the leather with vertical pores may be the synthetic leather. In addition, from the view of cross section, the cross section fiber of natural leather has its own characteristics, and the fiber thickness of each layer varies. The fiber layers of synthetic leather are basically uniform, with a plastic film on the surface. Natural leather is irregular in shape and uneven in thickness. Its surface is often more or less, light or heavy with some natural imperfections. Its surface is smooth with different degrees of fineness. Generally, the edges and abdomen are loose. Full face leather has obvious pores and patterns, and there are pile in the leather. The synthetic leather has uniform thickness, smooth surface, no natural defects, uniform pores and patterns, and no pile in the leather. Dripping test: the natural leather with strong water absorption is obvious, otherwise it may be artificial leather.
