Setup: To prepare your new adidas F50 SPARKFUSION boots for play, simply lace them up securely. Ensure the laces are tightened evenly across your foot to provide a snug yet comfortable fit without being too restrictive. A good lacing technique helps to prevent discomfort and provides optimal support. Compatibility: These boots are specifically designed for Firm Ground (FG) natural grass pitches and Artificial Ground (AG) synthetic turf. They are NOT recommended for use on soft ground (SG) or indoor surfaces, as this can damage the soleplate and compromise performance and safety. Care: Proper care extends the lifespan of your boots. After each use, remove any mud, dirt, or artificial grass pellets from the upper and soleplate using a damp cloth or a soft brush. If very muddy, rinse lightly with water. Avoid using harsh detergents, washing machines, or submerging them in water, as this can damage the materials. Always allow your boots to air dry naturally at room temperature, away from direct sunlight or heat sources like radiators, which can cause materials to crack or shrink. Removing insoles to dry separately can help prevent odor buildup. Stuffing with newspaper can help absorb excess moisture and maintain shape.
