Cristiano Ronaldo is known for his strong work ethic and his attention to personal health.
While many will consider that to be the reason for his success, Max Blau, the global vice-president for Nike Football Footwear, says Ronaldo‘s boot is the reason for his success.
According to Blau, the Real Madrid star shuns any boots that are black because it feels they do not make him fast.
He told Goal: “It all starts with him.
“I think he’s amazing, but he’s the first to say ‘I can improve’. He says he can get better and will do his part, but he needs us to do ours too.
"That puts a lot of pressure on us. We have to come up with something to help him.
"That's how we came up with the new Mercurial Superfly [the boots Ronaldo currently wears].
"Every player has their favourite colour, and it's been scientifically proven that the colour of the boots activates chemicals in the player's mind.
"When you feel better, you play better. The main reason of the colour is to give confidence.
"For example, Cristiano Ronaldo doesn't like to wear black boots because he says black looks slow and he wants to feel fast.
Could dodging black be the reason for Ronaldo's greatness or something else.
