The upper of the new Black Purple Nike Mercurial Superfly IV boot will feature NIKESKIN which is also seen on the Hypervenom Phantom boot. Along with NIKESKIN a new Dynamic Fit Collar first seen on the Magista Obra will be used offering enhanced comfort, fit and feel. FlyWire has been implemented for the first time in three years designed to maximise support and fit for an overall enhanced performance. A full length carbon fibre soleplate is added to work naturally with the foot offering super lightweight comfort and traction. The Superfly IV is designed for enhanced ball touch and control at high speeds as well as explosive acceleration and speed from the surface. The Vapor X also be available and will not feature FlyWire or the Dynamic Fit Collar seen on the Superfly IV boot.
Nike have equipped the New Black Nike Mercurial Superfly with an upper made of the lush and flexible Flyknit material. The material, which is also found on the Magista Obra, provides an unforeseen comfort and fit. As soon as you stick your foot into the Superfly, you will feel your foot become one with the boot, as if you were pulling on a pair of socks. But it is not just the Flyknit upper that provides a sock-like fit. Nike have also removed the tongue and instead equipped the boot with their Dynamic Fit Collar. It continues up the ankle, so the boot is not just a part of your foot, but actually both you foot, ankle and calf.
In order to generate even more touch and ball grip, the Flyknit upper has a Nike Skin cover, as well as a 0,1 mm thin ACC silicone layer. This results in a 3D-like texture that creates friction between boot and ball, which you will benefit from when dribbling at high speed, but also in connection with your passes and strikes.
To ensure that the upper of new Safari Black Purple Nike Mercurial Superfly Boots does not collapse and also to provide good stability in the boot, Nike have woven the brio-cables into the upper. The Brio-cables serve to keep your foot in place inside the boot and help provide the unique fit that you get from the Superfly. Furthermore, the Brio-cables will react to even the smallest movement, which results in a more optimal use of your speed.
