To begin using your adidas Predator League Football Boots, simply lace them up to achieve a snug and secure fit. These boots are specifically designed for use on artificial turf surfaces. Using them on natural grass or other surfaces may compromise performance and durability. For care, wipe down the boots with a damp cloth after each use to remove dirt and debris. Avoid harsh chemicals or machine washing, as this can damage the synthetic materials and rubber sole. Always refer to the care label inside the boot for specific instructions to maintain their condition and extend their lifespan. The composition is 100% Synthetic for both upper and lining, with a 100% Rubber sole.
