What are the types of shoe soles? What are the different kinds?

Types of shoe soles I. Outsole

The material of outsole is simply natural rubber or synthetic rubber.

(1) Natural rubber: the advantage of natural rubber is that it is very soft, elastic and good, and can be adapted to a variety of sports, but the disadvantage is also very obvious that it is not wear-resistant. Indoor sports shoes are mostly made of natural rubber.

Sole type 2, synthetic rubber is divided into wear-resistant rubber, environmental protection rubber, air rubber, sticky rubber, hard rubber, carbonised rubber.

(1) Wear-resistant rubber: wear-resistant rubber is very good abrasion resistance and toughness, so very durable, this rubber material is generally used in the outsole of tennis shoes.

(2) Eco-friendly rubber: also known as recycled material rubber, this rubber outsole contains Z more than 10% recycled rubber, the main purpose is for environmental protection.

(3) Air rubber: rubber contains air, has a certain shock-absorbing function, but not very wear-resistant, not very widely used.

(4) Viscous rubber: viscous rubber is characterised by better flexibility and is very non-slip, generally used in indoor sports shoes.

(5) Hard rubber: Hard rubber is the most comprehensive rubber in the outsole material, which is tough, non-slip and wear-resistant, and naturally has a wide range of uses. Multi-functional shoes and basketball shoes are mostly made of this kind of rubber.

(6) Carbonised rubber: Carbon is added to the ordinary rubber material, which makes the rubber tougher and more wear-resistant. Running shoes are mostly made of this kind of rubber, and there is a BRS letter marking on the rear palm of the sole of the running shoes to indicate that the outsole is made of carbonised rubber.

Sole type 3, glue to hit the outsole: this kind of outsole is not common, the raw material of this kind of sole is industrial glue, through the mixer's stirring, and then canned into the mould heating and shaping, which is characterized by soft and very non-slip.

Shoes sole type two, midsole

Now I don't think many people will know the midsole of sneakers, which is PHYLON midsole, and EVA midsole Z common. In fact, the two types of soles belong to the same attribute category that is (engineering plastics), but why there will be called on the different it PHYLON originated in the United States, Z early shoes are called PHYLON midsole, and there is no EVA midsole and PHYLON midsole points, and later with the continuous development of footwear products to Taiwan and South Korea's major brands of footwear R & D factories as a source of the name of the sole of more systematic. The name is divided into more systematic, there is what we now call the EVA midsole. Below I'll talk about the difference between EVA midsole and PHYLON midsole.

Now the shoe midsole with Z is PHYLON midsole, PHYLONZ big feature is lightweight, elasticity, good cushioning performance, PHYLON is known as the second foam, EVA midsole is also very light, but cushioning performance and elasticity is far less than the PHYLON midsole, the cost is also lower than the PHYLON is much lower than the EVA midsole is known as the first foaming. The reason why they have the same properties, but called different, different performance is because PHYLON is a secondary foam, while EVA is a foam.

(1) Primary Foaming: A shoe midsole that is shaped once after the material is injected into the mould and heated at a high temperature is called primary foaming midsole, which is also called EVA shoe midsole.

(2) Secondary Foaming: After injecting the material into the mould, the shoe midsole which is formed through two times of high-temperature heating is called secondary foaming midsole, which is also commonly known as PHYLON midsole.The softness and hardness of PHYLON is also controlled by the temperature. In the process of firing PHYLON midsole, the higher the temperature is, the higher the density of the PHYLON will be, and the harder the PHYLON will be. The smaller the fire, the lighter and softer the PHYLON will be, so the evaluation of the midsole cannot be measured by the weight or the degree of softness.

(3) Wrapped cloth burnt midsole: wrapped cloth burnt midsole is also PHYLON midsole, only that the designer uses a kind of shoe-making technology in order to pursue the overall design feeling, and a good example is that the midsole and the body of the shoe use the same kind of fabric, which makes the overall combination of the body and the sole, and it is also one of the highlights of the production process of this shoe. To achieve this process is to use the selected fabric to wrap the PHYLON midsole that has been shaped, and burn it at high temperature in the mould, which turns it into a shoe midsole with the same fabric texture that we see in LB1.

Sole type 2, PU midsole: In addition to PHYLON midsole and EVA midsole, PU midsole is also very common, and the Z big advantage of PU midsole is that it is more flexible and tough.
