The origin of liberation shoes?

In the early 1950s, with the start of china rubber industry, our army changed from wearing cloth shoes to wearing liberation shoes. Jiefang shoes have become the main shoes of our army and have been worn for more than 50 years. For more than 50 years, it has played an important role in military operations, training, productive labor and daily life.

Because liberation shoes are made of pure cotton and the uppers and soles are not strong, soldiers often "wear out five or six pairs of liberation shoes a year". In addition, the air permeability and moisture permeability of liberation shoes are poor, which is easy to breed bacteria and often emits an unpleasant smell. Some soldiers even suffer from beriberi infection, which affects their training.

In order to solve this problem, the vast number of researchers began to tackle key problems for 20 years. 1997 The Military Supplies Department of the General Logistics Department set up a research group on new training shoes. After hundreds of experiments, the new training shoes finally made a major breakthrough in the key technology of 10. In order to enhance the wear resistance of new training shoes, they developed new applied chemical fiber materials; In order to solve the antibacterial and deodorizing problems of new training shoes, they added antibacterial and deodorizing agents to the fabrics; In order to reduce the weight of shoes, they developed a new material of short fiber reinforced foam rubber, and adopted the world-advanced new shoe-making technology to make the new training shoes comfortable and beautiful. Last year, after the appearance of new training shoes with high-tech crystallization, they won 6 national patents and the first prize of military scientific and technological progress achievements 1 item.
