Nike Phantom GT Academy DF Junior FG Football Boots These Phantom GT Academy Football Boots have been developed with a Dynamic Fit collar which wraps your ankle for a comfortable and secure fit, while the textured synthetic leather upper helps improve control and durability and the open arch stud plate reduces weight to help keep you fast. The boots texturing on the upper is thicker and denser at the instep and toe for better grip and touch where you need it most, while the Nike Swoosh branding completes the look.
