Light travels fast. REALLY fast, 299,792,458 meters per second to be precise!
Nike have added that number to the swoosh on their new Mercurial Dream Speed 2 football boot!
These boots even LOOK fast – the transition of colours have been picked to represent the various frequencies of light!
We think Nike are trying to tell us: these boots will help you move FAST!
They will be on the feet of Cristiano Ronaldo, Kylian Mbappe and Sam Kerr – so look out defenders!
