Setup: To prepare your Nike Mercurial Vapor 16 Elite FG boots for play, simply put them on and adjust the lacing system. Start by loosening the laces completely, then tighten them from the toe upwards, ensuring a snug but comfortable fit that secures your foot without creating pressure points. Double-knot the laces to prevent them from coming undone during play. Compatibility: These boots are designed exclusively for Firm Ground (FG) natural grass pitches. They are not suitable for use on artificial turf (AG), soft ground (SG), or indoor surfaces, as this can lead to accelerated wear, poor traction, and potential injury. Care: To maintain your boots, wipe off all dirt and debris with a damp cloth immediately after each use. Do not use harsh detergents or put them in a washing machine or dryer. Allow them to air dry naturally at room temperature, away from direct sunlight or heat sources. Remove insoles if they are damp to allow for better air circulation inside the boot. Store them in a cool, dry place.
