Nike Mercurial Superfly X Academy FG MG - Green - UK 9

These boots feature a Multi-Ground (FG/MG) soleplate, making them suitable for both firm natural grass pitches and artificial grass surfaces.

Zoom Air cushioning is an integrated technology in the forefoot. It features a unique 'wave' stud pattern that maximizes the engagement of the Zoom Air unit when your foot meets the ground, generating increased energy return and a responsive, propulsive feel for enhanced speed.

The NIKESKIN upper is a lightweight, pliable synthetic material engineered to wrap your foot securely and bring you closer to the ball. Its textured surface enhances ball touch and control, aiding in precise dribbling and passing.

The Dynamic Fit collar provides a secure, sock-like fit around the ankle, enhancing stability and comfort. While designed to be comfortable, its snug nature might feel tight for some users initially and may require a short break-in period to conform to your foot shape.

After each use, remove excess mud and debris with a soft brush. For deeper cleaning, use a mild soap and lukewarm water, then wipe clean with a damp cloth. Allow them to air dry naturally at room temperature, away from direct heat. Store them in a cool, dry place.

Yes, the Mercurial range is endorsed by several top professional players, including Kylian Mbappe, Vinicius Jr, Cristiano Ronaldo, Sam Kerr, and Ada Hegerberg, highlighting its performance credentials at the elite level.

The Dynamic Fit collar and NIKESKIN upper are designed for a snug, sock-like fit. This is normal. Allow for a break-in period of a few training sessions to let the materials mold to your foot. Ensure you are wearing appropriate football socks. If discomfort persists after several wears, re-evaluate sizing.

First, ensure the pitch type is suitable for Multi-Ground (FG/MG) boots (firm natural grass or artificial turf). Check if the studs are clean and free from excessive mud or debris, which can hinder traction. If playing on extremely wet or soft natural ground, dedicated Soft Ground (SG) boots might offer better grip.

Utilize the finger loops located at the front and back of the collar. Pull them firmly to stretch the collar opening, allowing your foot to slide in and out more easily. Over time, the material may soften slightly with use, making it easier.
