UPPER: The Superfly II soccer shoes
have an ultra-thin Teijin upper that's lined with Flywire
filaments in a soccer-specific cabling pattern to deliver a precise fit and optimal support. Asymmetrical lacing enlarges the contact zone.
INSOLE: The Nike Superfly II has a contoured sockliner with a Superfly EVA insole.
OUTSOLE: Carbon fiber composite plate is the lightest and strongest outsole Nike has to offer. It has a pressure-activated adaptive traction system for speed in all conditions. The difference between a soft and firm ground stud is 3mm. So Nike has developed a new stud that extends 3 mm when ground is soft for increased toe-off acceleration and traction. These two longer studs in the forefoot also prevent slippage and create the most comfortable feeling Mercurial ever.
