The history of shoes has long developed, and the production of shoes is an important industry in the light industry of China and is a component of the clothing industry. There are many methods for classifying shoes according to wearing objects, manufacturing processes, uses, and the like. Wherein, sports shoes refer to shoes that people wore when carrying out sports, and its generalized concept specifically is: training processes for fitness, leisure, recreational and professional competitive sports and shoe types for formal competitive sports.

The support, rebound, and stability provided to the body when wearing a pair of high performance athletic shoes is determined in large part by the sole of the shoe. The sole structure of most athletic shoes is broadly divided into: an outsole (or outsole, or ground contact layer) for engaging the ground and primarily providing wear resistance, and a midsole disposed between the outsole and the insole. In order to pursue high performance athletic footwear, it is desirable that the sole be neither too hard nor too soft, and that there be sufficient support protection and rapid energy feedback. The too hard sole easily causes the wearer to feel uncomfortable against the foot when wearing, and if the sole is too soft, the wearing comfort is good, but the sole is not good in shock absorption due to the too soft sole and provides insufficient support force to the human body, so that the wearer easily sprags the foot and it is difficult to provide support force when walking or running for a long time. If the rebound of the sole is not enough, the energy consumption of the wearer is high after long-time movement, and the fatigue feeling is easy to generate.

Therefore, how to ensure that the sole has both the supporting and shock-absorbing function and the rapid rebound function is an important technical research and development project.
