The day after winning the gold medal in the men’s 100m race at the Paris Games, Noah Lyles set his sights not on more titles and records but on a more fashion-oriented goal; having a pair of trainers named after himself. “I want my own shoe. I want my own trainer. Dead serious,” he told reporters. Not a trainer for fellow athletes to run in, he emphasised, but a shoe with the same legendary potential as an Adidas Stan Smith (named after the former US tennis champion) or Nike’s Air Jordan (the namesake of basketball player Michael Jordan).
