Nike Mercurial - Green - UK 11

These are FG/MG (Firm Ground/Multi-Ground) boots, designed for optimal performance on natural firm grass pitches and modern artificial grass (AG) surfaces.

After each use, brush off loose dirt. Use a soft cloth or sponge with lukewarm water (and mild soap if needed) to wipe down the upper and soleplate. Avoid harsh chemicals or machine washing. Allow them to air dry naturally away from direct heat.

The NIKESKIN upper is pliable and may offer some adaptability. However, the Mercurial line is generally designed for a snug fit optimized for speed. If you have particularly wide feet, it's recommended to try them on to ensure comfort, as individual fit can vary.

The Zoom Air unit in the forefoot provides responsive cushioning. It compresses on impact and then springs back, generating energy return that helps propel you forward and enhances your explosive speed and responsiveness on the pitch.

'Academy' refers to a tier in Nike's football boot range. It signifies that these boots offer excellent performance and key technologies inspired by top-tier models, but at a more accessible price point, making them ideal for aspiring players and regular use.

These boots are not recommended for traditional flat indoor court surfaces or older 'astroturf' (often resembling carpet). They are specifically designed for natural firm ground and newer artificial grass (AG) pitches. Using them on unsuitable surfaces can damage the boots and may affect performance or safety.

The Dynamic Fit collar is designed to provide a snug, secure fit. During the break-in period, it will adapt to your ankle. Ensure you are pulling it up correctly and that your socks are smooth underneath. If it still feels too tight after a few wears, ensure your sock choice isn't adding unnecessary bulk.

This is common with new synthetic boots. Wear them for several shorter, low-intensity training sessions (e.g., 30-60 minutes) to allow the NIKESKIN upper to mold to your foot shape. Consider wearing thicker socks initially.

Ensure you are using the boots on appropriate surfaces (Firm Ground or Multi-Ground artificial grass). Using FG/MG boots on extremely hard ground, older artificial turf (2G), or abrasive surfaces like concrete will accelerate stud wear. Clean the soleplate regularly to prevent mud buildup from affecting traction.

Moisture and bacteria cause odours. After each use, allow the boots to air dry completely. Remove insoles if possible to aid drying. You can also use shoe deodorizers, baking soda, or place activated charcoal packets inside the boots when not in use.
