Development of sports shoes
We will find again the fever of the Olympic Games. Our top racers compete at the highest level and strive for the highest honors in their chosen territory.
Most of the older ones will remember rubber tire gloves that traditionally wear in PE-watches at most European schools. These colors were of any color as long as they were black or white.
These were replaced by honeycomb, gel-filled capsules that provide excellent technical performance. They come in different colors, shapes and shapes, and are so much available for their appearance as their performance.
The pioneering manufacturing technique that allows the development of plimellol has been called vulcanization, which is still used today. This process uses heat to mix rubber and clothing. The rock is used during the process.
Plimsolls were revolutionary at the time because they were comfortable, light and made it easy for the user to move quietly. The Plimsolls are recognized as shoes and sold in America in 1917.
For four years after the last Olympics in Athens, technology has moved slightly and has been moving since the days of Plimsoll.
Trainers and clothing became lighter and stronger. But which part does technology need to increase Olympians' performance [http://nike-trainers.com/index.php?option=com_content&task=view&id=21&Itemid=2]?
There are trainers and sports shoes, we have different shoes for each event, and each pair of shoes is made of a variety of materials because of their individual qualities, placing strength and flexibility where they are most needed. Materials such as Kevlar, which are ten times stronger on the skin, skin, or canvas, both thin, stable and low density foamed polyurethane, which provides extra padding and thermoplastic polyurethane, which makes a shoe more robust and flexible  In the development of technology, scientists have developed new complex materials that together produce better performance than two or three separate materials.
Different materials offer different properties than stability; which is resistant to twisting and twisting. When a substance is fed to a substance over a certain period of time, it creeps (settles and spreads).
Some materials are used for their elastic properties, they tend to bend and bend when force is applied and retain their original shape when the force is removed. Finally, certain materials are selected to explain their density because the amount of objects in space can be measured, these materials are usually used for shock absorption.
Polyurethane is a unique material that offers the elasticity of the tire combined with the rigidity and durability of the metal. The flexible polyurethane type can be used for upholstery, mattresses, earplugs, chemically resistant coatings, special adhesives and sealants, and packaging. It also comes in the cool form of buildings, water heaters, cooling water, and commercial and residential cooling. They are used for the production of sporty shoes due to their light shock absorbing properties and are flexible and have a high torsion and bending force. Kevlar is one of the most important man-made organic fibers ever developed. The fiber has properties that, since the 1970s, have resulted in a wide variety of products according to the invention. Kevlar fibers consist of long chain molecular chains derived from polypeptylene terephthalamide. Kevlar offers high tensile strength, low weight, structural stiffness, low electrical conductivity, high chemical resistance, low thermal shrinkage, high dimensional strength, high cutting resistance, flame retardancy and self-extinguishing. Very versatile is true!
Thin running shoes have been in existence for more than 100 years by the British company Reebok in the 1890s. Thin shoes have necessarily evolved. The founder of the company enjoyed running and wanted to develop shoes that would increase his speed.  In 1925, a company known as Adi Dassler, known as Adidas, forged pincushion. They offered different shoes for different distances. The company used the strongest and richest materials to produce running shoes. Adi Dassler's brother continued the Puma sports shoes company.
The involvement of science and technology in the 1970's sports shoes manufacturers led experts to carry out research on people's operations. The effect of shock and shock between the body and the legs was also studied. Their finding helped to develop new, more advanced sports shoes.
This is where the runner's heel comes into contact with the ground and the foot moves in a straight line as it advances
This is where the runner's heel is in contact with the ground and the foot moves in a straight line as it advances
where the corner reaches the ground, but this time the foot moves to the side as it moves forward. This refers to the inward coil of the foot
This is the place where the heel reaches the ground and the foot moves outward.
In modern times, materials such as foam, silicon, air or gel were added to the instructors to create a modern running shoe cushioning system.
In the 1970s, the "ethylene vinyl acetate (EVA)" plastic was developed. This material has revolutionized the construction of sports shoes. It consists of small air bubbles that provide cushioning and absorb shock. These molds are molded in shape and serve as a corner holder.
Nike Air Technology, using the gas-filled airbag on the foot of the shoe to kick off the run, first appeared in 1979. some shoes were called; The rear wind and these technically advanced air pumps have provided a good foundation for further Nike developments. Since then, athletic shoes have become increasingly specialized and the prices of different shoes have increased according to technological advances and value-added features. Some of the shoes sold in the 1980's also contained a pump valve to inflame or lower the shoe's shoes as if it were a bicycle tire.
A technical breakthrough occurred in 1972 when Bill Bowerman, studying the pattern of gofri iron, came up with a great idea – the waffle sole. Bowerman then cooked gas in the waffle iron and glued it to the bottom of a shoe he later tested for athletes. The athletes came back with great feedback and the shoes were well received on the market. The patented base revolutionized the running, as it offered better adhesion in lighter, more durable shoes.
In 2003, the US spent on average $ 50 (£ 28) on a sports shoe.
Companies sponsor most athletes. This means they are lucky enough to wear the company's products during a sports event.
The Olympics is the world's largest sporting event that attracts worldwide television viewers. This is an ideal opportunity for sports companies to get acquainted with their products. Athletes are not just athletes but athletes as well, they are fantastic marketing tools.
It would not be interesting if this year's Olympic athletes had to wear plummeters, the only choice they knew would be black or white
We'll see the real Olympic champions.
