Summary Description:
Rubber soles are made from rubber, and the materials used can generally be categorized as either natural rubber or synthetic rubber.
The advantage of natural rubber is its exceptional softness and excellent elasticity, making it well-suited for a wide range of sports and providing effective shock absorption. However, its major drawback is its poor wear resistance, which is why indoor athletic shoes often use natural rubber.
Synthetic rubbers are further classified into wear-resistant rubber, environmentally friendly rubber, air‑filled rubber, adhesive rubber, hard rubber, and carbon‑reinforced rubber. Below, we will provide a detailed introduction to each type.
Wear‑resistant rubber: This material boasts excellent abrasion resistance and toughness, making it highly durable. It is commonly used for the outsoles of tennis shoes.
Eco-friendly rubber: Also known as recycled rubber, this type of rubber outsole contains up to 10% recycled rubber, primarily for environmental sustainability.
Air rubber: Rubber containing air, offering some shock-absorbing properties but with limited abrasion resistance, so its applications are not very extensive.
Adhesive rubber: Adhesive rubber is characterized by its excellent flexibility and superior slip resistance, and it is commonly used in indoor athletic shoes.
Hard rubber: Among outsole rubber compounds, hard rubber is the most versatile—tough, slip‑resistant, and highly wear‑resistant—making it suitable for a wide range of applications. Most multi‑purpose shoes and basketball shoes use this type of rubber for their outsoles.
Carbon‑infused rubber: Carbon is added to standard rubber compounds, enhancing their toughness and abrasion resistance. Most running shoes use this type of rubber, and the outsole of the heel area often bears the “BRS” marking to indicate that carbon‑infused rubber has been used in the midsole.
