What Is The Merit Of Sports Shoes?

Different football shoes and running shoes.

The torsion system of sports shoes can correct the foot shape and movement, and the upper support to the ankles, through the "breathing" function of the stoma, can make the shoes breathe and absorb moisture.

Almost all sports have their own special shoes.

It is also the volume of a monograph to describe briefly.

But football shoes are particularly worth mentioning separately.

Football is all about one foot, and the foot is counting on a pair of shoes.

Every game, footballers run about ten thousand meters, and the speed of 100 meter sprint should be reached.

More importantly, sports shoes are football players' racket and bat.

The power of catching, dribbling, passing and shooting must be issued by sneakers. The delicate footwork of pushing, dialing, picking, dragging, and buckles should be completed through sneakers.

The precise sense of foot and the combination of shoes and feet are very important.

Inspired by the small particles on the table tennis racket, with the rubber imitation toe on the edge of the football shoes, the Falcon sneakers on Zidane's and Beckham's feet can kick out 8 circles of banana balls per second.

The 100 meter sprint of a century ago increased by an average of 0.015 seconds per year, and now it has slowed to 0.006 seconds a year.

People are paying more and more attention to the potential of running shoes.

According to the test, the weight of each running shoe increases by 100 grams, and the athlete's physical energy consumption will increase by one percent. In the 1991 Tokyo track and field world championships, the American sprinter Lewis broke the world record of 100 meters with only 115 grams of weight. At the 2000 Sydney Olympics, the "golden hamstring shoes" of the "field Agam" Michael Johnson weighed only 116 grams, while Marian Jones's "crystal shoes" only had 99 grams; the Canadian "black leopard" Bailey's running shoes were described as "socks with spikes".

People can't help wondering why some athletes can wear heavy gold necklaces around their necks, but they are so heavy on the weight of shoes.

Looking at those fast flying feet on the 100 meter runway, it is found that each athlete's heels almost touch his hip. Folding the calf can shorten the radius of rotation of the hip joint, thus reducing the rotational inertia and increasing the angular speed of rotation.

And the feet are at the far end of the knee around the knee and the rotation radius of the hip joint, so a slight reduction in the weight of the shoes will bring a significant reduction in leg inertia.

This is undoubtedly a great "burden reduction" for the two feet alternately marking the arc at the speed of 20 meters per second.

Poland holds an annual "KUSO Shinseki international track and field competition" to commemorate the excellent Poland athlete Janusz Kusosinski who was killed by German Nazis in the World War II prison camp.

In 1932 Losangeles Olympic Games, when Shinseki won the gold medal of 10000 meters, his feet were so bloody that he could not take off his shoes.

"Shoes are uncomfortable and only toes know," it is no wonder that in sports circles, a famous saying goes, "wearing the wrong shoes is a disaster."

Before the 1968 Mexico Olympic Games, FOSS Berri, the inventor of the back style high jump, received Adidas's sneakers from Europe. But he only tried it and returned it.

The courteous businessmen persisted in revising the shoes until they were sent to Fos Berri for the fourth time.

Today's sports stars are blessed. Many manufacturers compete to customize their "unique" sneakers for them.

The expert group spent several years in advance to track and study the characteristics of athletes, and get accurate foot models.

The data of three dimensional motion capture, pressure sensing, infrared imaging and laser scanning are input into the computer.

Then discuss with athletes and try again and again to achieve perfection.

This "symbiotic relationship" between sports stars and big name manufacturers has promoted the improvement of athletic performance and the development of shoemaking industry after all.
