Setup: The adidas Predator Elite Tongue FG boots feature a classic `lace closure` system. To ensure an optimal fit, loosen the laces thoroughly before putting the boots on. Once your foot is comfortably seated within the `Primeknit collar`, tighten the laces evenly from the toe upwards, securing them with a firm knot. The foldover tongue, complete with a strap, should be adjusted to lie flat over the laces for an integrated feel and clean strike zone. Compatibility: These boots are specifically designed for `firm ground (FG)` surfaces. This means they are best suited for natural grass pitches that are dry or slightly damp. Using them on artificial turf (AG), soft ground (SG), or indoor surfaces may compromise performance, traction, and the longevity of the soleplate studs. Care: To ensure your Predator Elite Tongue FG boots maintain their performance and appearance: - Cleaning: After each use, wipe down the `HybridTouch upper` with a damp cloth to remove dirt and debris. For stubborn mud, a soft brush can be used gently. Avoid harsh chemicals or abrasive cleaners. - Drying: Allow the boots to air dry naturally at room temperature. Do not expose them to direct heat sources like radiators or sunlight, as this can damage the materials. - Storage: Store the boots in a cool, dry place away from direct sunlight. Consider using boot trees or stuffing them with newspaper to help maintain their shape. - Soleplate: While the lacquer finish on the soleplate may wear off during play, this is normal and will not affect the boot's performance. Regular cleaning of the studs will help maintain traction.
