In the wardrobe of each person you can find a pair of sneakers. They are used both for sports and in everyday life. They are practical, comfortable and aesthetically pleasing.
The general concept of creating sneakers
What is the top made of?
The upper provides protection for the foot and its retention on the sole. For its production, both natural and artificial materials are used.
Materials for the upper sneakers:
genuine leather is durable and elastic, perfectly retains its shape and allows air to pass through;
- artificial leather has a light and strong structure, retains its shape under any operating conditions;
- Textiles are nylon and polyester, lightweight, good air permeability.
These are the basic materials for making sneakers. Each manufacturer is constantly improving tailoring technology. A large amount of raw materials is presented, which performs certain functions.
They also use polyurethane, which is durable and hard. Often used a combination of filon and rubber - filite. It is used in conjunction with outsole, which increases flexibility and makes running shoes easier.
Important! Polyurethane is increasingly being replaced by lighter materials not only in the sole, but also in the upper part.
The cheapest option is EVA. It is light in weight and has good elasticity, as it consists of foam. Gradually, air is squeezed out of the granules, and the sole is no longer able to return to its previous shape.
Materials for the main sole:
- BRS 1000 - a complex complex of rubber with carbon, designed for running;
- combination of natural and artificial rubber - a universal material for any sports shoes;
- DRC mixture - regular rubber with additives, used for tennis and walking;
- Duralon - a type of artificial rubber, provides high cushioning, is used for running.
