To prepare your Nike Mercurial Vapor 16 Elite FG boots for play, first loosen the laces completely. Slide your foot into the boot, ensuring your heel is comfortably seated. Then, starting from the toe, gradually tighten the laces, working your way up to the ankle, until you achieve a snug, secure, and comfortable fit without any pressure points. Double-knotting the laces is recommended to prevent them from coming undone during play. These boots are exclusively compatible with Firm Ground (FG) natural grass pitches. Using them on Artificial Grass (AG), soft ground (SG), or indoor surfaces is not recommended as it can damage the soleplate, affect your stability, and potentially void any warranty. For care, after each use, wipe down the boots with a damp cloth to remove dirt and grass. Use a soft brush to clear any mud from the studs and soleplate. Allow the boots to air dry naturally in a well-ventilated area, away from direct sunlight or heat sources like radiators, which can damage the materials. Do not machine wash or tumble dry. Storing them with boot trees can help maintain their shape and prevent creasing.
