What material is good for leather shoe soles

In life, many people like to wear leather shoes, because leather shoes are not only comfortable to wear, but also have good breathability. If you walk too much, sweating on your feet will make you feel uncomfortable, and the breathable function of leather shoes can perfectly cover this defect. In addition, the selection of leather soles is also relatively strict. So what material is better for leather shoes? Let me introduce to you

Business leather shoes:

1. Outsole

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

(1) Natural rubber: The advantage of natural rubber is that it is very soft and elastic, and can be suitable for various sports, but its disadvantage is also obvious, that is, it is not very wear-resistant. Indoor sports shoes are mostly made of natural rubber.

2. Artificial synthetic rubber is divided into wear-resistant rubber, environmentally friendly rubber, air rubber, sticky rubber, hard rubber and carbon-added rubber.

(1) Wear-resistant rubber: Wear-resistant rubber has excellent wear resistance and toughness, so it is very durable. This rubber material is generally used on the outsole of tennis shoes.

(2) Environmentally friendly rubber: also known as recycled rubber, this type of rubber outsole contains up to 10% recycled rubber, the main purpose of which is environmental protection.

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

(4) Sticky rubber: Sticky rubber is characterized by good flexibility and is very non-slip. It is generally used in indoor sports shoes.

(5) Hard rubber: Hard rubber is the most comprehensive rubber in the outsole rubber material. It is tough, non-slip and wear-resistant, so it is naturally widely used. Multi-functional shoes and basketball shoes mostly use this kind of rubber as the outsole.

(6) Carbon-reinforced rubber: Carbon is added to ordinary rubber materials to make the rubber tougher and more wear-resistant. Most running shoes use this type of rubber, and the letters BRS are marked on the back of the sole of the running shoe to indicate that the outsole uses carbon-reinforced rubber.

3. Glue outsole: This type of outsole is not common. The raw material of this outsole is industrial glue, which is stirred in a blender and then poured into a mold and heated into shape. It is soft and very non-slip.

2. Midsole

1. I think many people know the midsoles of sneakers nowadays even if I don’t say it. PHYLON midsoles and EVA midsoles are the most common. In fact, both midsoles belong to the same property category (engineering plastics), but why are they called differently? PHYLON originated in the United States. The earliest shoe midsoles were all called PHYLON, and there was no distinction between EVA midsoles and PHYLON midsoles. Later, with the continuous development of footwear products, some major brand footwear product research and development factories in Taiwan and South Korea were the source, and the names of the midsoles were divided more systematically, and we have what we now call EVA midsoles. Now I will talk about the differences between EVA midsoles and PHYLON midsoles in a simple way.

The most commonly used midsole for shoes now is PHYLON midsole. The biggest feature of PHYLON is that it is light, elastic, and has excellent shock-absorbing performance. PHYLON is called secondary foaming. The EVA midsole is also very light, but its cushioning performance and elasticity are far inferior to the PHYLON midsole, and its cost is much lower than that of PHYLON. The EVA midsole is called a single foaming. The reason why they have the same properties but different names and performances is that PHYLON is a secondary foaming material, while EVA is a primary foaming material.

(1) One-time foaming: The shoe midsole that is formed in one step after the material is injected into the mold and heated at high temperature is called a one-time foaming midsole, that is, EVA shoe midsole.

(2) Secondary foaming: After the material is injected into the mold, it is heated twice at high temperatures and then fired into a shoe midsole, which is called a secondary foaming midsole, which is what we often call a PHYLON midsole. The hardness of PHYLON is also controlled by temperature. During the firing process of the PHYLON midsole, the higher the temperature, the greater the density of the fired PHYLON, and the harder it is.
