Nike has launched a new running shoe that complies with limits
set by World Athletics after the governing body imposed a landmark ban
on a version of the sportswear giant’s Vaporfly shoes that was used to
run the first sub-two hour marathon.
The first-ever
shoe ban by World Athletics (WA) last week addressed concerns that
technology advances are giving athletes an unfair and unnatural
advantage, described by some critics as “technological doping”.
New
rules state road shoes must have soles no thicker than 40mm and not
contain more than one rigid, embedded carbon fibre plate, and limit the
use of some track spikes on the Vaporfly models, but permit the
continued use of most of the range.
Nike has now duly
launched the latest incarnation of the shoe—the Air Zoom Alphafly
Next%—with one carbon plate and a sole thickness of 39.5mm, as well as
newly added air pockets.
“We are pleased the Nike Zoom Vaporfly series and Nike Zoom Alphafly NEXT% remain legal,” said the US company.
“We will continue our dialogue with World Athletics and the industry on new standards.”
The Vaporfly controversy has ignited a wider sporting debate:
where should the line be drawn between advances in sports technology and
equipment giving competitors an unfair advantage, be it running shoes,
soccer boots or tennis rackets?
Nike has always said it operates within the rules, while exploring the possibilities provided by new technology.
Its
Vaporfly shoes have led to a slew of world records since their
introduction in 2016 but WA ruled last week that most of the versions
used for those records, and by thousands of amateur runners, would
remain legal.
Kenyan runner Eliud Kipchoge used a
version of the Vaporfly now deemed illegal for his unofficial sub-two
hour marathon in October, a model reportedly with extra-thick soles and
three carbon plates.
He is expected to use the Alphafly
in his London marathon showdown with Ethiopian rival Kenenisa Bekele in
April’s London Marathon.
After launching the new shoe on Wednesday, Nike CEO John Donahoe said it did not give athletes a “mechanical advantage”.
“It’s
simply using the same materials that go into a shoe and putting them
together in an innovative way that allows the athlete to do their very
best in a safe way,” Donahoe said in an interview with CNBC.
A Wall Street Journal
report said limited numbers of the new Alphafly shoes will be made
available to the public online this month, thereby meeting one of WA’s
eligibility requirements for the shoe to be used at this year’s Tokyo
Olympics.
