These boots feature a traditional lace closure system. To set up, simply thread the laces through the eyelets and tie them securely to your preferred tightness, ensuring the foldover tongue is positioned comfortably. Compatibility: The adidas Copa Gloro FG boots are specifically designed for Firm Ground (FG) surfaces. This means they are best used on natural grass pitches that are firm and dry. They are not recommended for use on artificial grass (AG) or soft ground (SG) surfaces, as this can affect performance, traction, and potentially damage the boots or increase injury risk. Care: To maintain the quality and longevity of your leather boots, follow these care instructions: 1. After each use, wipe off excess dirt with a damp cloth. 2. Allow them to air dry naturally at room temperature, away from direct heat or sunlight. 3. Avoid machine washing or using harsh detergents. 4. Regularly apply a leather conditioner to keep the leather supple and prevent cracking. Always refer to the specific care instructions provided with the product. Important Sizing Note: If you have not purchased this specific product before, it is recommended to go up half a size from your usual shoe size to achieve the perfect fit.
