Today I understand (and have seen explained) that the new spikes (which are apparently allowed) are still clearly faster. I can understand how that is unfair towards older athletes who were not allowed to renew their material.Yes, thankfully the turbocharged Nike 100m spikes were not approved, so I don't expect Bolt's record will be broken but it's a matter of time something equivalent to be approved in the future.
Still, just as Jesse Owens, it will be extremely difficult to "break" his legacy.
