The famous "magic shoes" in World War I
On the tree-lined path of the Vienna Park, Kipchoge ran 42 kilometers with a time of 1 hour 59 minutes and 40 seconds, winning the first race and putting his running shoes in the spotlight of the world. Is it because of these shoes that you ran into the 2-hour mark for the first time in human history?
The IAAF has made its attitude clear before the Kipchoge Challenge. The challenge was carried out in an environment comparable to that of a laboratory. The weather conditions and road conditions were carefully selected, and the super "rabbit" team took turns to assist, and the electric car cleared the way to indicate its speed. Therefore, the IAAF cannot recognize 1 hour 59 minutes and 40 seconds as the new world record for men's marathon.
However, IAAF did not notice the "special edition" shoes worn by Kip George, nor did it emphasize that running shoes were unqualified factors.
The next day, Kenya's Kosky put on the same series of running shoes, which improved the world record of women's marathon, which had been dusty for 16 years, by 8 1 second. Careful media statistics show that the top 10 runners in this competition are all wearing this series of running shoes.
The IAAF launched an investigation.
Although the ingredients are doubtful, the curative effect has been remarkable. According to The Times, about 20 athletes, including Italian marathon champion Gianni Demadonna, wrote to IAAF a few months ago complaining about Nike's marathon sports shoes technology. Track and field researchers are also discussing whether the carbon fiber plates used for running shoes have spring effect.
After receiving the complaint, IAAF has organized an expert group to investigate the matter. The IAAF said it would report the situation after two months' investigation. Up to now, IAAF has not questioned the compliance of this series of running shoes. Kipchogg also wore this series of running shoes when he set a world record of 2 hours 1 minute and 39 seconds last year.
For athletes' competition shoes, IAAF stipulates in the rules manual that the purpose of wearing shoes during competition is to protect their feet, make them stable and firmly grasp the ground, and the design of competition shoes "cannot give athletes any unfair help or advantage".
Will it be the "shark skin" in track and field?
The controversy about super running shoes now reminds people of the "shark skin" swimsuit of that year. At that time, this kind of fast swimsuit simulated the design of shark skin, and made the world record fragile with dense high-tech materials covering the whole body.
Obviously, the fast swimsuit has brought the progress of swimming technology and new understanding. The same is true for running shoes. Nike executives said that carbon fiber soles have long been used in the production of running shoes. They make sure to help athletes within the rules set by IAAF, and don't use any illegal springs or similar things.
Running shoe manufacturers including Sokoni and Adidas have also become suitors. Both companies have announced the launch of their new running shoes, hoping to continue to break through the limits of human marathon.
Those who wear magic shoes are not necessarily gods.
The demonstration benefit of breaking 2 has shown that more and more runners wear the same running shoes in domestic marathon venues. However, experts also warned that running shoes suitable for professional marathoners may not be suitable for ordinary runners.
Matt Powell, vice president and industry analyst of NPD Group, a market research company, pointed out that it is difficult to know exactly whether these shoes have affected Kipchogg's running speed. He believes that it is necessary to count the achievements of other players who wear these shoes to participate in the competition and see if there are similar findings.
Kris chris hart, the boss of Naperville Running Company, also believes that anyone who wears a pair of running shoes that can effectively rebound will run faster. "But unless there is an engine inside, this pair of shoes will not make ordinary runners a' great god' who breaks 2."
In fact, although this running shoe has been popular all over the world in the past year, many runners have mixed comments after using it. Some runners praised it, claiming that it made running easier and faster, and it really deserved its reputation; Some runners also reported that the carbon board made their forefoot feel hard, which affected the toe scraping action and made them obviously uncomfortable to wear.
There are also research papers about runners wearing these running shoes. Through the analysis of the data of landing force, pace frequency and landing time, it is considered that sometimes the pace frequency of runners will be slightly reduced and the landing time will be slightly extended. This may indicate that the "magic shoes" may be suitable for higher-level runners, such as runners who have been running for less than 4 hours. A slower runner may wear magic shoes, and he will not be a "great god".
