The Nike Mercurial Vapor XV Elite FG boots are designed for straightforward use. To set up, simply loosen the refined central lacing system, slide your foot in, and tighten for a secure, adaptive fit. The lacing system accommodates a wider range of foot shapes, ensuring comfortable entry.These boots are specifically engineered for Firm Ground (FG) surfaces. They are compatible with natural grass pitches that are dry or slightly damp. Using them on artificial turf (AG) or soft ground (SG) may damage the studs and compromise performance.For care, regularly clean your boots after each use. Remove excess mud and dirt with a soft brush or cloth. Wipe down the Vaporposite+ upper with a damp cloth. Allow them to air dry naturally, away from direct heat sources, to maintain material integrity. Do not machine wash or tumble dry. Remove insoles for airing to prevent odor buildup.
