Usain Bolt believes he would have run the 100 metres in under 9.5 seconds if he wore shoes with the new wave of super spikes.
The spikes feature a lighter energy-returning foam and are said to be worth at least a tenth of a second over the distance.

“How can I argue if World Athletics decide that it’s legal? I can’t do anything about it.

Bolt, 34, also pledged his support to British sprinter Adam Gemili who said he would take a knee on the podium at this month's Tokyo Olympics.
The International Olympic Committee recently reiterated that protests on the field of play and the podium are banned.
