Adidas X Copy? Real Madrid Superstars Show Off Next-Gen Nike Mercurial Vapor 2018 World Cup Boots

Real Madrid midfielders Casemiro and Isco have been spotted wearing blackout prototypes in training recently.

Casemiro and Isco Train in Next-Gen Nike Mercurial Vapor 12 Cleats

Both Isco and Casemiro trained in the upcoming Mercurial generation.

Totally blackout to hide the final design, the boots worn by Isco and Casemiro would be extremely hard to identify as Mercurials if both players would be no regulars of the Nike Mercurial Vapor football shoes since several years.

If we look at the visual appearance and tech of the boot, the next-gen Nike Mercurial football boots are totally different to the previous generation, and, visually, remarkably similar to the Adidas X football boot. They ditch the traditional synthetic upper of the Nike Mercurial Vapor in favor of Nike's Flyknit while also featuring a low-ankle collar.
