Nike’s Mercurial football boot franchise was first launched for Brazilian striker Ronaldo in 1998.
The Mercurial was created for speed and explosive attacking movement. Its lightweight construction and bright, attention-grabbing designs helped distinguish it from more traditional leather football boots of the period.
Ronaldo wore the boot during the 1998 FIFA World Cup, giving the new franchise immediate global visibility. Nike subsequently developed many Mercurial generations for fast forwards and wingers, including versions associated with Cristiano Ronaldo.
The Mercurial is often confused with Nike’s Tiempo line. Tiempo emphasizes a classic, leather-influenced control heritage, while Mercurial has consistently been marketed around speed, lightness and acceleration.
