Shoe Sole Classification

< p > 1, big bottom: < /p >

< p > the material of the 1. bottom is simply the use of natural rubber or synthetic rubber.

< /p >

< p > (1) natural rubber: the advantage of natural rubber is that it is very soft, elastic and suitable for all kinds of sports, but the drawback is also obvious, that is, it is very non wearable.

Indoor sports < a target= "_blank" href= "http://www.91se91.com/" > shoes < /a > use of natural rubber.

< /p >

< p > 2. the synthetic rubber is further divided into wear-resistant rubber, environment-friendly rubber, air rubber, sticky rubber, hard rubber and carbon rubber. < /p >

< p > (1) wear resistant rubber: wear resistance and toughness of wear resistant rubber are very good, so it is very durable. This rubber material is generally used in the outsole of < a href= "http://www.91se91.com/news/" > tennis shoes < /a >.

< /p >

< p > (2) environment-friendly rubber: also known as recycled rubber, this rubber outsole contains up to 10% of the recycled rubber, the main purpose is to protect the environment.

< /p >

< p > (3) air rubber: Rubber contains air, which has a certain damping function, but it is not very wearable, and its use is not very extensive.

< /p >

< p > (4) viscous rubber: sticky rubber is characterized by good flexibility, and very skid resistant, generally used in indoor sports shoes.

< /p >

< p > (5) hard rubber: hard rubber is the most comprehensive rubber in the material of the rubber, which is tough, skid resistant and wearable.

Multifunctional shoes and < a href= "http://www.91se91.com/news/index_c.asp" > basketball shoes < /a > mostly use this rubber to make the sole.

< /p >

< p > (6) adding carbon rubber: adding carbon to ordinary rubber material, making rubber more tough and wearable, most of the rubber used in running shoes, and the letter marks on the back of the sole of the running shoes will be left with BRS letters to indicate the use of carbon rubber at the outsole.

< /p >

< p > 3. glue sole: this kind of sole is not common. The raw material of this kind of bottom is industrial glue, which is made by mixing the mixer and heating into the mold. The feature is soft and very slippery.

< /p >

< p > two, middle bottom: < /p >

< p > 1. now < a href= "http://www.91se91.com" > sneakers < /a > bottom. I don't think many people will know that PHYLON is the middle and EVA bottom is the most common.

In fact, the two midsole belong to the same attribute category (namely engineering plastics), but why is there a difference in calling? PHYLON originated in the United States, the earliest shoe bottom is called PHYLON, and there is no difference between EVA midsole and PHYLON middle bottom. Later, with the continuous development of footwear products, the brand name products of Taiwan and Korea are being systematized, and we have what we call EVA middle end.

Next I will introduce the difference between EVA midsole and PHYLON bottom.

< /p >

"P" now the most of the bottom of the shoe is the bottom of the PHYLON, the largest feature of PHYLON is light, good elasticity, good shock resistance, PHYLON is called two foams.

EVA midsole is also very light, but the cushioning performance and elasticity are far less than the PHYLON midsole, and the cost is much lower than that of PHYLON. The EVA midsole is called a foaming.

The reason for their different attributes is that the PHYLON is the two time and the EVA is a foaming.

< /p >

< p > (1) one time foaming: when the material is injected into the mold and heated by high temperature, the sole of the shoe is called a foaming middle sole, that is, the middle sole of the EVA shoe.

< /p >

< p > (2) two times foaming: after the material is injected into the mold, the middle sole of the shoe is molded by the two high temperature heating. It is called the two foaming middle sole, which is what we often call the PHYLON middle sole.

The hardness of PHYLON is also controlled by temperature. In the process of firing PHYLON, the higher the temperature, the greater the density of PHYLON and the harder it is.

The smaller the temperature is, the lighter and softer the PHYLON will naturally burn. So the evaluation of the middle sole of the shoe can not be measured by the weight or the degree of hardness.

< /p >

< p > (3) the middle of the cloth is covered with cloth: the middle sole of the cloth is also the middle sole of the PHYLON, but only a target= "_blank" href= "http://www.91se91.com/". < < /a > > a kind of shoe making technology used in pursuit of the overall sense of design. The best example is that the middle sole and shoe body of the shoe are of the same kind of a target= "_blank", "a" and "cloth", so that the combination of the shoe body and the sole is a highlight of the shoe making process.

To achieve this process is to use the selected cloth to wrap the already formed PHYLON middle sole, and to burn it in the mold at high temperature will become the sole of the shoe that we see in LB1.

< p > 2.PU midsole: in addition to PHYLON midsole and EVA midsole, PU midsole is also very common. The biggest advantage of PU is elasticity and toughness.

< /p >

< p > 3. medium bottoms: now many sneakers are built with a built-in bottom structure, also called the bottom of the bag.

Like the T-MAC series that you are familiar with, the Feng style series of Nike belong to the bottom structure of the package. The bottom of the package consists of two parts, the outsole and the vamp, from the outside. But the structure is composed of three parts: the bottom, the middle sole and the upper part.

< /p >

< p > three, insole and integral sole: < /p >

< p > 1. insole: the insole can also be considered as a form of the bottom of the package, which is different from the bottom of the package. The bottom structure is wrapped in the bottom of the shoe sole, for example, FORCE1, even the inner bottom structure, rather than the overall rubber outsole as seen by the exterior. Actually, the inside of the rubber outsole is covered with the sole of the shoe, which is also called the MD midsole, which belongs to the EVA foaming.

< /p >

< p > 2. integral sole: < /p >

< p > (1) the integral sole is the most commonly used EVA foam sole. The sole is at the bottom of the cost, and the skid resistance is poor. When the sole is stained with water, it is like wearing roller skates.

The 3D soles of REEBOK are the best spokesmen for this EVA foam sole.

< /p >

< p > (3) PU whole soles: ADI and NIKE are not very popular when using this kind of soles, PU soles are low temperature molded soles.

The bottom of PU is characterized by portability, but it is not suitable to touch water. After encountering water, it will react with chemicals and corrode layer by layer.

< /p >

< p > (4) pure rubber soles: pure rubber soles are mostly used for outdoor mountaineering shoes, or work shoes, electrician shoes.

The whole sole is made of rubber. The advantages are abrasion resistance and skid resistance. The disadvantage is that the weight is too large.

Working shoes usually use this soles, also known as insulating soles.
