Before your first game, ensure a proper fit. Loosen the `off-centre lace fastenings`, slide your foot in, and then tighten the laces progressively from bottom to top, ensuring a snug but comfortable fit around your foot and the `Dynamic Fit collar`. These boots are specifically designed and compatible with Firm Ground (FG) pitches, which are natural grass surfaces that are usually dry or slightly damp. Avoid using them on artificial grass, soft ground, or indoor courts to prevent damage to the boots and ensure optimal performance. For care, always refer to the specific instructions on the product label. Generally, after each use, wipe off any mud or dirt with a damp cloth and allow them to air dry away from direct heat. Do not machine wash or tumble dry, as this can damage the materials and technologies.
