Nike Mercurial Vapor 16 Pro FG - Black - UK 4

These boots are specifically engineered for Firm Ground (FG), meaning natural grass pitches that are dry or slightly damp. They are not recommended for artificial grass or other surfaces.

The Zoom Air unit, engaged by the cascading wave traction, provides responsive cushioning and increased energy return. This means more spring in your step, helping you maintain speed and agility for longer periods on the pitch.

Yes, the Flyknit upper is designed to mold and adapt to your foot's shape over a short break-in period, offering a personalized and supportive fit. However, for significantly wider feet, the initial fit may be very snug.

After each use, brush off loose dirt. Use a damp cloth with mild soap for more stubborn grime, then wipe clean. Air dry them away from direct heat or sunlight. Avoid machine washing, as it can damage the materials.

No, these FG boots are not recommended for artificial grass. The stud configuration designed for natural grass can lead to excessive stud pressure on AG, potentially causing discomfort, premature wear to the boots, or increasing the risk of injury.

The tacky skin finish is applied to the Flyknit upper to enhance your ball control. It provides a better grip on the ball, allowing for more precise dribbling, passing, and shooting, even at high speeds.

Ensure you have chosen the correct size. The Flyknit upper needs a break-in period; wear them for shorter periods during practice. Try different football socks, which can impact fit and friction. If discomfort persists, consider a half-size larger.

Verify that you are playing on a suitable firm ground surface. Clean the soleplate and studs thoroughly after each use to prevent mud and debris buildup, which can hinder traction. Check for excessive wear on the studs; heavily worn studs may indicate it's time for a new pair.

Always clean your boots properly after use and allow them to air dry away from direct heat. Ensure you are only using them on appropriate firm ground surfaces. Playing on artificial turf or hard ground can cause excessive abrasion and accelerate wear on the upper.
