- World record holder will wear Alphafly Next%s on Sunday
- Critics of shoe should ‘open their hearts and move on’
Eliud Kipchoge has rejected suggestions that the next generation of game-changing Nike shoes violate the spirit of sport, even though he has conceded that they could give him a major advantage in Sunday’s London Marathon.
The world record holder confirmed that he would wear the Alphafly Next%s, which resemble platform shoes and are claimed to improve running economy by between 5-8%, for the first time in an official race.
