Nike Mercurial Superfly 9 Academy

Drive Your Speed
The speed cage inside of the structure is made of a thin but strong material that secures the foot to the outsole without adding additional weight for optimal lockdown.
Dig In, Take Off
Based on Nike Sports Research Lab analysis of player movements, the rubber outsole is designed to provide multidirectional traction on street, court and indoor surfaces.
Improved Fit
Flyknit wraps your ankle in soft, stretchy fabric for a secure feel. A redone design improves the fit, so that it better simulates the foot. We did this by conducting multiple wear tests on hundreds of athletes. The result is a more contoured toe box and better lockdown in the heel.
Barefoot Feel
The upper has NikeSkin, a soft and flexible mesh material linked together by a thin coating. It helps provide ball control and truly gives you a feeling of barefoot soccer.
