1. Leather shoes. The leather surface of cowhide shoes has fine grain, dense and small pores, thin skin, fine fibers, tight weaving and firmness.
2. Pigskin shoes. Pig leather has good air permeability and abrasion resistance, but the surface is rough and not smooth, there are obvious “product” shaped hairs, elasticity and water resistance are poor, and it is easy to swell and deform after absorbing water.
3. Sheepskin shoes. The upper leather of sheepskin shoes is mostly made of goat leather. Because goat leather has a thin surface and large elongation, it is soft and comfortable after being formed, with smooth and fine grain, and it is easy to dye bright colors, so it is mostly used in the production of women’s leather shoes and children’s leather shoes.
4. Artificial leather shoes. Artificial leather shoes are made of vinyl chloride foam artificial leather as the top leather, rubber-like products as the bottom, and viscose. Artificial leather shoes are light, beautiful, and inexpensive. But the disadvantages are: poor air permeability, not too strong, and easy to harden at low temperatures.
