THE SCIENCE OF SPEEDFITDeveloped around the idea of a racecar fit, the Superfly V features a new V16 last, which is designed to engage the major metatarsal by shaping the outsole to the natural contours of your foot. This allows the metatarsals to sit lower in the boot while the big toe is slightly raised, increasing flex across the joint and allowing you to generate maximum power when sprinting off the mark.Constructed with a Flyknit and NikeSkin upper, the Superfly features an upgraded tongue less construction, while the Flywire cables within the upper are independently able to react to how the foot is engaging with the ground for optimal lockdown. To reduce the loss of elasticity over time, the Dynamic Fit collar has a tighter knit construction to enhance your proprioception with the ground, while its internal anti-skid top cloth eliminates any foot movement within the boot.TOUCHTo enhance your touch and feel, the Superfly V features a new 3-D textured Speed Rib construction, which is knitted into the boot’s Flyknit upper to create increased friction on the ball for high-speed control. Applied with Nike’s All Conditions Control (ACC) Technology, the Superfly provides consistent levels of grip on the ball in wet and dry weather conditions.TRACTIONRedesigned to improve your acceleration, the Superfly’s chassis is made from compressed Nylon, which is 40% lighter than the Carbon Fibre plate used for the Superfly IV. More responsive and shaped to the anatomical V-16 last, the soleplate features a mix of chevron shaped and metal screw-in studs for quick ground penetration, release and braking on soft natural grass surfaces.Features Include:Please note that these are football boots designed and constructed for the sport of football.
