Setup: These boots require `zero break-in time`. Simply lace them up to achieve a secure and comfortable fit tailored to your foot. Compatibility: Designed as `unisex` adult football boots, they are suitable for players of all genders. The `mixed ground (MG)` soleplate makes them compatible with both `firm natural grass (FG)` and `artificial grass (AG)` surfaces. Care: To maintain the performance and longevity of your Nike Tiempo Legend X Academy boots, clean them after every use. Wipe off mud and dirt with a damp cloth. For persistent stains, use a mild soap solution and a soft brush, then wipe clean. Allow the boots to air dry naturally, away from direct sunlight or heat sources, as extreme heat can damage the `FlyTouch Lite` material. Do not machine wash or tumble dry. Proper storage in a cool, dry place will help them retain their shape and feel.
