Your young striker will feel the difference the moment they lace up (well, pull on) the Nike Mercurial Superfly 10 Academy KM in the Mbappé Pack colorway. Built for the players who live for that explosive first step and the breakaway moment, these youth soccer cleats blend speed-first design with the kind of ball control that keeps attackers dangerous in the box. The NikeSkin upper with embedded chevrons gives that barefoot touch without sacrificing durability, while the responsive heel Air Zoom pushes them forward through every transition. On synthetic surfaces and shorter grass, they'll feel locked in and ready to create.
- NikeSkin upper with embedded chevrons for enhanced ball control and barefoot-feel touch.
- Improved heel Air Zoom unit delivers a propulsive sensation for explosive acceleration.
- Dynamic Fit collar wraps the heel with soft, stretchy fabric for a secure, locked-in feel.
- Laceless design with pull tabs and strap closure for a quick, seamless fit.
- Adaptive stretch mesh provides flexibility and support while keeping the foot close to the ball.
- Rubber outsole designed for traction on synthetic surfaces and shorter grass.
- Cushioned insole for comfort during extended play.
- Inspired by Kylian Mbappé's fearless attacking style, in a bold Grand Purple and Pale Ivory colorway.
