Building on the 360-degree Flyknit innovation of the 12, the Nike Mercurial Vapor 13 Elite FG adds a Nike Aerowtrac zone to the forefoot and a slightly stiffer chassis to help supercharge traction. Inside, an insole with NikeGrip technology provides maximum interior traction underfoot and lightweight cushioning. High-Tenacity Fit 360-degree Flyknit construction wraps your foot for a second-skin fit. New high-tenacity yarn and a one-piece lining create a close, secure feel on the pitch. All-Weather Touch A new ultra-thin NIKESKIN overlay gets you closer to the ball for a precise touch at high speeds. The All Conditions Control (ACC) finish means you get reliable touch in wet and dry conditions. Explosive Acceleration The lightweight forefoot plate features a Nike Aerowtrac zone with micro grooves. The angular studs combine with a new stiffer chassis for explosive acceleration with every step.
