Shoes have a long history of development. About 5000 years ago, during the period of Yangshao culture, the most primitive shoes made of animal skin appeared. Shoes are a tool for people to protect their feet from injury. In order to overcome the special situation, people invented fur shoes at first. The development of shoes to the present, has formed the present appearance. Shoes of various styles and functions can be seen everywhere.
In the primitive age of gathering and hunting, the role of wild animals was not limited to eating. Intelligent human beings would peel off the skin of animals with simple stone tools and use it as clothes and shoes. People wrap the animal skin on their feet, cut part of the animal skin into pimps, and tie the whole piece of animal skin on their feet. In winter, the shoes are covered with animal hair, while in summer, the animal hair is outside, forming the most primitive "leather shoes".
