Nike’s Air Zoom Alphafly NEXT%, a version of the prototype that Kipchoge wore when he ran a marathon at 1:59:40 in Vienna last October, is said to provide a 4% boost in running economy, the amount of work to be done by a runner. do at a certain speed, compared to other top racing shoes

Kichoge’s run in Vienna was endorsed by the petrochemical company Ineos in an attempt called the 1:59 Challenge, although the milestone did not count as a world record.

During the race, Kipchoge followed behind a car, a condition not allowed by IAAF sanctions, and was assisted by an army of 30 pacemakers.

Some critics have argued that the advancement in technology is akin to doping, although Kipchoge defended the shoe before Sunday’s race.
“We live in the 21st century and we must embrace change,” Kipchoge told reporters. “Second, development goes hand in hand with technology. The shoe is good. We are virtually holding a press conference, isn’t that technology? We should embrace technology and marry technology.

“It’s good for Nike. On the other hand, it’s a business. It’s good for Nike to be much higher than other companies when it comes to technology,” he responded when asked if it provided an unfair advantage over other athletes.

Nike was not immediately available for comment, but on its website the clothing manufacturer describes Kipchoge’s time of 1:59:40 in Vienna as an “extraordinary achievement – that was” years in the making. “

“Our premier racing shoe is loaded with new technology and innovation including two ultra-responsive Zoom Air pods in the forefoot and additional ZoomX foam in the heel.”

‘Electric shock’

Long distance times have fallen since Nike’s Vaporfly range was introduced in 2016, including Brigid Kosgei’s 2:14:04 marathon in Chicago last year, beating Paula Radcliffe’s previous record that had been held by one minute. for 16 years.

Following a review of leading running shoes earlier this year, World Athletics approved Nike’s Vaporfly range, but banned shoes with soles larger than 40mm or with more than one plate to enhance their spring.

As of April 30, it also banned from competition any footwear that had not been on public sale for four months. The new rules meant that the latest Alphafly shoes, believed to have a 39.5mm thick sole, are acceptable.

However, not all elite athletes sponsored by Nike are fans of the Alphafly shoe. Ethiopian Kenenisa Bekele, who is widely seen as Kipchoge’s main rival at the London marathon, told reporters that he had suffered a series of nasty injuries and will instead wear an older version this weekend.

The Air Zoom Alphafly NEXT% will be commercially available later this year.
“It’s really difficult to fit into these shoes, especially with sprint training,” said Bekele, 38, in quotes published by The Guardian.

“Several times I had some minor injuries, like a muscle strain, because the shoe is not stable underfoot. It is really deformed, it is very soft. The muscle needs to adapt to the movement under it. It is really difficult. No one can wear the shoe. . “

Bekele, a three-time Olympic gold medalist, posted a time of 2:01:41 at the Berlin Marathon in September 2019, just two seconds off Kipchoge’s world record.

However, both Kipchoge and Bekele said their training regimens had been affected by the coronavirus pandemic.

“It was really difficult when I had to train alone because for 17 years I have been training with six, 10 or 20 people all year long. So it was like an electric shock when I had to train alone,” he said. Kipchoge.

“It was difficult to get in shape and reach a high level of training. But lately we have consolidated a bigger team around me and the training has been good.”

Ethiopian Kenenisa Bekele trains ahead of the London Marathon on Sunday.  The 40th race will take place on a closed circuit around St James's Park in central London.

Bekele added: “My preparation was good, but due to Covid-19 it was sometimes not as perfect as I had planned.

“It was very difficult in Africa, so it affected us a lot. We did everything we could to prepare well and more or less I have prepared well.”
