Setup: To prepare your new F50 Sparkfusion Elite boots, simply slide your foot in, appreciating the adaptive `Midcut Primeknit collar` which offers a snug, supportive fit. Then, tighten the traditional lace closure to your desired level of lockdown, ensuring a secure and comfortable feel across your foot. Compatibility: These boots are designed for use on `Firm Ground (FG)` and `Artificial Ground (AG)` pitches. Using them on other surfaces, such as indoor courts or street, may compromise performance and durability. Care: To maintain the condition of your boots, clean them after each use. Remove loose dirt with a soft brush, then wipe the upper with a damp cloth. For the soleplate, use a brush to clear any mud or debris from between the studs. Allow the boots to air dry naturally at room temperature, away from direct heat sources. Avoid machine washing or drying. Please note that the lacquer finish on the bottom of the boot is designed to wear off during play and this will not affect the product's performance.
