The World Athletics task force investigating the Nike shoes that revolutionized marathons is still deliberating what limits should be placed on carbon plate and foam technology and is unlikely to put put in place a wholesale ban.
The Guardian understands the group met again on Wednesday and intends to announce its findings by the end of the month. But sources suggest that, contrary to the headlines about the shoe ban, the issue remains up for debate.
As it stands, the group’s focus seems to be more on limiting future incarnations of the technology, which was first introduced in 2016, rather than restricting Vaporfly shoes altogether.
One option being considered is to limit the size of foam midsoles in all shoes, which would make the next-generation AlphaFly shoes worn by Eliud Kipchoge during his sub-two-hour marathon in Vienna illegal.
Kipchoge insists it’s wrong to focus on his Nike shoes. “They are fair,” he told the Telegraph. “I trained hard. Technology is growing and we can’t deny it – we have to keep up with technology.
It’s also been suggested that similar shoe technology was used to power Laura Muir’s spikes on the track last year. However, sources close to her say that is “categorically” not the case.
