Nike Air Zoom Mercurial Superfly IX Elite Firm Ground 。Nike Mercurial Superfly 9 Elite Firm-Ground Soccer Cleat. With the eye-catching design of the Superfly 9 Elite, you immediately dominate the playing field. We\'ve added a Zoom Air element designed specifically for football, plus a grippy structure on top for a great feel to the ball so you can dominate in the replay minutes – just when it matters. The 3/4-length Air Zoom unit sits in the outsole and provides another level of springy underfoot feel that helps you move fast on the field. It creates separation when it matters the most—whether you\'re scoring goals, being first to the ball or going by defenders. Tri-star studs provide multidirectional traction with every step, so you can change directions quickly and confidently. Heel studs provide traction and stability when braking. Toe-off center studs give you traction during quick starts. A redone design improves the fit, so that it better simulates the foot. We did this by conducting multiple wear tests on hundreds of athletes. The result is a more contoured toe box and better fit in the heel. The upper is made of Vaporposite+, which combines a grippy, grid mesh with a premium lining for optimal ball control at high speeds. The lining provides a tactile feel across the surface of the upper. It’s soft, but stable and wraps tightly around your foot.
