Analysis Of The Depth Of The Bottom Of Key Parts Of Football Shoes

The sole part of the shoe is the key part that determines the stability of the shoes.

For a good sneaker, the middle sole is equivalent to the suspension system of the car. The middle position is between the upper and the outsole, which is the most important part of the shoe, because the midsole can provide the best stability and shockproof effect for the sneakers, and has the function of absorbing impact. Besides, the major brands in the midsole will also combine their own excellent cushioning technology to support them. As we know most, it is also the most visible and visible NikeAIR professional air cushion, as well as the adidas bounce system, as well as the early Reebok honeycomb mitigation and DMX technology. Of course, it also includes the early CONVERSE's exclusive oil cushion technology of CONVERSE. These advanced technologies have brought a lot of lasting classics to the configuration and design of the midstream, greatly enhancing stability and protection. But if we throw away the advanced technology, what material should support and cooperate in a good midsole is the significance of our topic.

　　 Analysis of commonly used materials in midsole

EVA material

EVA material is soft, light weight, agile and sports shoes are also economical and practical materials, so it is commonly used in middle and low price shoes. This kind of midsole is usually made of steel die cutting, instead of PU or PHYLON, so there is a lot of savings in the cost of work, but such savings are by no means a result of abandoning the effect. EVA midsole, as a commonly used midsole material, is still unquestionable in supporting and slow motion. The only defect is the endurance. The EVA midsole will become flat when the air is discharged after being used for a long time. Once it is pressed, it will not restore the original shape, and it will lose the function of shock absorption indirectly. So it is a kind of material that is easier to be compressed. When you choose these sneakers, you should not buy too expensive styles, and do not recommend friends with stronger stamina.

PHYLON material

The PHYLON midsole material is similar to the EVA material. It belongs to the medium and low quality material with low price. Its advantages are light weight and easy fabrication. Compared with EVA material, PHYLON is more sensitive to external force. If we start from the production, PHYLON is the evolution of EVA material, which is heated and foamed by EVA plastic particles, then injected into the model to compress and compress material. The PHYLON material has excellent changeability. It can shape different shapes according to the needs of each pair of shoes, but this material has its outstanding shortcoming, that is, it is not easy to corrode and is environmentally friendly.

PU material

The material is made of PU foam, which is made into a jelly, and then heated into foam. The PU surface has a smooth rubber feeling. Therefore, it brings excellent stability and toughness, and the abrasion resistance is greatly enhanced. However, this material has caused a lot of headache for many of our shoe collectors, because the PU midsole will be yellowed after frequent exposure to air, and many classic shoes choose PU material as a part of the middle sole. Therefore, it is very troublesome to maintain, and only by sealing. However, from the development process of the shoes, PU is indeed the most important material in the middle of the floor, and it is also the most suitable medium for sneakers. PU mid sole material is the medium density, the most wearable and stable middle sole of all kinds of materials.
