To set up your F50 League SG boots, simply thread the laces through the eyelets and tie them securely. The lace-up design, combined with the stretchy tunnel tongue, allows for a customizable, locked-down fit. Ensure the laces are snug but not overly tight to maintain comfort and prevent restriction of movement. These boots are specifically designed for `soft ground` (SG) surfaces, meaning muddy or damp natural grass pitches. They are *not* recommended for firm ground (FG) or artificial grass (AG) surfaces, as the metal-tipped studs can cause damage to the pitch and the boots, and compromise player safety. Please note that for smaller sizes (UK Child 2.5 and below), the soleplate comes with six metal-tipped studs only, while larger sizes (UK Child 3 and above) feature additional, moulded plastic studs as pictured. After each use, clean mud and debris from the `Sprintplate 360` outsole and studs using a soft brush and water. Wipe the `Fiberskin` upper with a damp cloth. Allow the boots to air dry naturally at room temperature, away from direct heat sources, which can damage the synthetic and textile materials. Regularly check the condition of the studs for wear and tear, especially the metal-tipped ones, to ensure optimal performance and safety.
