Evolution Of Sports Shoes

We're back in the middle of Olympic fever. Our athletes at the highest level of competition and fighting for top honors in their field.

Most will remember the old rubber-soled plimsolls that were traditionally worn in physical education in most schools in Europe. These are available in any color you want as long as it's black or white.

They have been mitigated by air, gel filled capsules were replaced by superior technical performance. They come in a variety of colors, shapes and forms and so much to buy for their appearance than their performance.

The advanced manufacturing technology, the development of vulcanisation Plimsoll which today is open. This process uses heat of rubber and fabric merge. Sulfur is used during the process.

Plimsolls were revolutionary at the time they were mounted easily and allows the user to move quietly. Took the name of sport shoes and plimsolls were widely sold in America 1917th

During the four years since the last Olympics in Athens technology has moved a few movements and certainly since the time Plimsoll.

Trainers and clothing has become lighter and stronger. But that was part of the technology has to play in improving the performance [http://nike-trainers.com/index.php?option=com_content&task=view&id=21&Itemid=2] of our Olympians?

developed casual shoes and sports shoes, we have different shoes for each event and each pair of shoes is made from a variety of materials, because many manufactured chosen by their individual characteristics, implementation, and flexibility, where it is needed most. Materials such as Kevlar, which is ten times stronger than leather, leather or canvas that is both thin, stable and blew a low density polyurethane foam, shoe cushioning and thermoplastic polyurethane, which is to a strong and flexible shoe.

As technology has developed, scientists have new composite materials that work together to produce a better performance than the two or three separate documents.

Different materials have different properties, such as stability, resistance to twisting and warping. When the weight is, a material is applied over a longer period Creep (flatten and spread).

Certain materials are used for their elastic properties, the ability to bend and flex when force is applied and then retain their original shape when the force is removed. Finally, some materials are known for their density, which can be explained as the amount of matter in an object is selected for each measurement of space, these materials are typically used for shock absorption.

Polyurethane is a unique material that the elasticity of rubber with the strength and sustainability of supply of metal combined. The flexible nature of polyurethane padding is used to make, mattresses, earplugs, coatings resistant to chemicals, specialty adhesives and sealants, and packaging. It also comes with rigid forms of building insulation, water heaters, refrigerated transport and commercial refrigeration and residential. It is used in the manufacture of sports shoes because of its light absorption properties and the flexibility and high torsional and bending rigidity. Kevlar is one of the most important manmade organic fibers ever developed. The fiber possesses a remarkable combination of properties that allowed its use in a variety of commercial products since its invention in the 1970s. The Kevlar fibers are affiliated with long molecular chains produced from poly - terephthalamide paraphenylene. Kevlar has a high tensile strength with low weight, structural rigidity, low electrical conductivity, high chemical resistance, low thermal shrinkage, good dimensional stability, high cut resistance, flame retardant and self-extinguishing. Pretty versatile really!

Running shoes spike was created for it 100 years ago by the British company Reebok in the 1890s. The stiletto shoe was developed by necessity. The founder of the company enjoyed running and I wanted a shoe that would develop its speed increased.

In 1925 a company called Adidas Adi Dassler now known created a series of spikes forged by hand. They offered a range of shoes for different distances. The company has used lighter materials and boxes available at the time of making the sneakers. Adi Dassler's brother then found that the company Puma sneakers.

The integration of science and technology in the 1970s, manufacturers of sports footwear for expert research staff, wonder how people walk. They also studied the effect of shock on the body by the collision between the feet and the ground has caused. Your research has helped to develop new and improved athletic shoes.
Their research revealed three types of operation styles:

Neutral

This is the heel of the wheel touching the ground and travel on foot in a straight line, does as it moves forward.

Pronation:

This is where the heel touches the ground, but this time the foot moves to the side as it moves further. It refers to the role of the foot.

SUPEN:

This is the heel on the ground and the foot rolls outward meets.

In modern materials such as foam, silicon, air or gel were added to the trainers, they were creating damping in modern running shoes.

In the 1970s, a plastic called ethylene-vinyl acetate (EVA) was developed. This material is revolutionizing the construction of sports shoes. He was of small air bubbles that cushion and absorb shock shocks. This material is injected into molds, which are formed as supports heel.

The Nike Air technology, a bag filled with air gas inserted in the sole of the shoe, which serves to cushion the impact of current, was published in 1979. The pair of athletic shoes has been appointed; Tailwind and these high-tech air-plant had become a good basis for further developments Nike provided on the base. Since then, the sport has become increasingly specialized and prices of various athletic shoes rose in line with advances in technology and its value-added features. The shoes in the 1980s, even sold a pump valve included so you can vent the blow or the heel of the shoe, as if they were bicycle tires.

After the introduction of Nike shoes] http://nike-trainers.com/index.php [, a technical breakthrough in 1972, Bill Bowerman, while studying the pattern on a waffle iron, came with a brilliant idea - soles waffle. Bowerman then some rubber in his waffle cooked on the floor and stuck a pair of shoes, which he later admitted to test the athletes. The athletes came back with good reviews and the sneakers were welcomed on the market. The patented outsole revolutionized running by better traction in a lighter, more durable shoe.

In 2003, the average American spent 50 USD (EUR 28) on a pair of sneakers.
Companies that sponsor the most elite athletes. This means they pay a fortune to carry the company's products during a sporting event.

The Olympics are the biggest sporting event in the world, attracting viewers worldwide. This provides an ideal opportunity for sports companies the opportunity to see their products. In addition to being fine-tuned athletes and athletes, athletes are now fantastic marketing tools for businesses of sneakers.

Would not it interesting that all athletes should wear plimsolls in the Olympic Games this year, the only choice that could make the color would be black or white?

We see the true Olympic champion then.

I try to convey my thoughts on life and experiences in a way that people find interesting to read.
