Providing insight and feedback to the design team, Messi was integral to the development of the Messi15 and as such the boot has been designed to suit the Gambeta – the uniquely Argentinian playing style adopted not only by Messi, but also past Argentinian greats. The Gambeta style is all about keeping the ball close to your feet, using shoulder drops and feints to fool your opponent, particular skills that have long been associated with Messi.The messiTOUCH material which makes up the upper has an x-ray surface for lethal grip, stability and foot-fitting comfort. The unique messiFRAME provides a locked-in fit, stability and maximum traction. The messiPRINT offers round forefoot studs, which alongside the messiGAMBETRAX combine to provide a dynamic stud configuration and outsole that delivers explosive movement for the dynamic player.
