The Mercurial Vapor is a football boot manufactured by Nike. The boot is known for being lightweight. Because of this, the boot is endorsed by many players for whom speed is a very important part of their game, notably wingers or strikers, such as Cristiano Ronaldo, Franck Ribéry, Zlatan IbrahimoviÄ‡, Didier Drogba, Jesús Navas, Eden Hazard, Xherdan Shaqiri, Raheem Sterling, Stephan El Shaarawy, Alexis Sanchez and others.
In 1998 Nike launched the first Mercurial football boot — a shoe inspired by and designed for Brazilian star Ronaldo, which he debuted at the 1998 World Cup. The boot is in its tenth version the Nike Mercurial Vapor X.
The boot is available in either Soft Ground (SG) (now Soft Ground Pro; SG-Pro) or Firm Ground (FG) versions. The SG version's sole plate is fitted with six NikeSnap removable studs,(now with molded plastic studs) which can be purchased in different lengths, for the first and second models, and traditional screw-in aluminium studs for versions 3 to 8; the FG version has seven moulded blades
