Definition and characteristics of sneakers

Definition
Rubber soled sports shoes refer to sports shoes with soles made of rubber or synthetic rubber and similar materials. This footwear design is designed to provide excellent wear resistance, slip resistance and good cushioning to meet the needs of various sports. The material of rubber or synthetic rubber not only gives the sole a strong and durable character, but also ensures its stability and grip in a variety of ground conditions.
Peculiarity
Wear resistance: The sole material of the rubber soled sports shoes has been specially treated to have excellent wear resistance. This means that even after a long time of use, the sole can maintain better shape and performance, extending the service life of the shoe.
Anti-slip: Rubber and synthetic rubber and other materials have excellent anti-slip properties. Whether on dry or slippery ground, rubber sneakers provide a stable grip, reduce the risk of slipping and ensure the safety of the athlete.
Cushioning: The sole design of sneakers usually contains cushioning technology, such as air cushion, foam, etc. These techniques can effectively absorb the impact force during sports, protect the joints and ligaments of the foot from damage, and improve the comfort and health of sports.
Adaptability: The sole design of the sneakers is flexible and changeable, and can adapt to different sports needs. Whether it is running, basketball, football or other sports, there are special sneakers styles to choose from to meet the characteristics and requirements of different sports.
Stability: The sole structure of the sneakers is carefully designed to provide stable support. This helps the athlete maintain correct posture and balance during exercise, reducing sports injuries caused by improper posture.
Comfort: In addition to the above functional features, sneakers also focus on comfort. The upper material is usually a breathable, soft material to ensure that the feet are dry and comfortable. At the same time, shoe sizes and shapes have been carefully designed to fit the needs of different foot types.

Sneakers material and classification

Material
The material of sneakers is mainly concentrated in the sole part, usually made of rubber or synthetic rubber and other similar materials. These materials have the following characteristics:
Rubber:
Natural rubber: Latex from rubber trees and other plants, with excellent elasticity, wear resistance and skid resistance. However, due to the high price and limited resources, the use of natural rubber in sports shoes is limited.
Synthetic rubber: Through artificial synthesis of high molecular compounds, with similar properties to natural rubber, but lower cost, greater yield. Synthetic rubber can be formulated according to different use needs to meet the specific requirements of sports shoes.
Other materials:
In addition to rubber and synthetic rubber, some sports shoes may also use other materials as part of the sole, such as EVA (ethylene-vinyl acetate copolymer), TPU (thermoplastic polyurethane elastomer) and so on. These materials have the characteristics of lightweight, good elasticity, wear resistance, etc., can be used in combination with rubber to improve the overall performance of sports shoes.

sort

There are many ways to classify sneakers, and the following are some common classification methods:
By sport:
Running shoes: Designed for running, with a focus on lightweight, cushioning and breathability. The sole is usually made of wear-resistant rubber or synthetic rubber to provide good grip and stability.
Basketball shoes: According to the characteristics of basketball, emphasis on support, stability and cushioning. The sole is usually made of high wear-resistant rubber or specially formulated synthetic rubber to cope with high intensity direction changing and jumping action.
Football shoes: According to the different football field (such as grass, artificial grass, indoor field, etc.), the sole design of football shoes is also different. Generally, lightweight, wear-resistant rubber or synthetic rubber materials are used to ensure that the player can maintain a stable grip when running fast and changing directions.
Other sports shoes: such as tennis shoes, badminton shoes, table tennis shoes, etc., also have their own unique design characteristics and material requirements.
Classification by functional features:
Cushioned sports shoes: pay attention to cushioning effect, suitable for people with large weight or who need to stand and walk for a long time. The sole usually uses special cushioning materials and technology to reduce the impact force of the foot during exercise.
Support sports shoes: emphasize the support of the feet, suitable for people with arch collapse, flat feet and other problems. The sole and upper design is usually more closely fitted to the foot shape to provide stable support.
Lightweight sports shoes: The pursuit of light and flexibility, suitable for sports that need to move quickly and change direction. The sole material is usually light and has some flexibility to reduce the burden during exercise.
Classified by material combination:
Rubber +EVA combination: This combination combines the wear resistance of rubber and the lightness of EVA, making the sneakers have both good durability and a certain degree of comfort.
Rubber +TPU combination: TPU material has excellent
