Getting started with your Nike Mercurial Superfly 10 Pro FG boots is straightforward. Simply use the lace closure to secure them to your foot, adjusting for a snug yet comfortable fit that optimizes the locked-in feel provided by the speed-cage and Dynamic Fit collar. These boots are specifically designed and optimized for Firm Ground (FG) surfaces, which typically include natural grass pitches that are not excessively wet or muddy. Using them on other surfaces, such as artificial turf (AG) or very soft ground (SG), may reduce their performance, cause premature wear, or even void warranties. For proper care and to maximize the lifespan of your boots, always refer to the specific care instructions on the product label. Generally, after each use, wipe off excess dirt with a soft, damp cloth. Avoid using harsh chemicals or machine washing. Allow them to air dry naturally, away from direct heat sources or sunlight, and avoid storing them in damp conditions. Regularly check the studs for wear and tear.
