Nike Mercurial Superfly - Green - UK 5.5

FG/MG stands for Firm Ground / Multi-Ground. This means the soleplate and stud configuration are designed to perform optimally on both natural grass pitches (firm ground) and artificial grass surfaces.

After use, wipe off loose dirt and mud with a soft brush or damp cloth. For a deeper clean, use a mild soap solution and a sponge. Do not machine wash or tumble dry. Allow them to air dry naturally at room temperature, away from direct heat.

The Zoom Air unit is Nike's responsive cushioning technology. In these boots, it's strategically placed in the forefoot with a unique wave traction pattern. When your foot hits the ground, it compresses and then quickly springs back, providing energy return that propels you forward and helps maintain speed.

The NIKESKIN upper is designed to offer a close, adaptive fit. While it will mold to your foot over time, players with particularly wide feet may find the fit snug. It's always recommended to try them on to ensure a comfortable fit.

NIKESKIN is a proprietary synthetic material used in the upper of these boots. It's engineered to be lightweight, pliable, and durable, providing a comfortable, supportive fit that brings your foot closer to the ball for enhanced touch and control.

No, these boots are specifically designed for outdoor firm ground and artificial grass surfaces. The stud configuration is not suitable for indoor courts or hard street surfaces and can cause damage to the boots and potentially lead to injury.

Yes, a short break-in period is recommended. Wear them for a few lighter training sessions before full-intensity matches to allow the materials to soften and mold to the unique shape of your foot, ensuring maximum comfort and performance.

Ensure you have the correct size. Try wearing thinner socks initially. The NIKESKIN upper is designed to mold, so allow a break-in period during light use. If discomfort persists, consider resizing.

Verify the playing surface is compatible with FG/MG studs (natural grass or artificial turf). Clean the soleplate thoroughly, as mud or debris can reduce traction. If playing on very soft or wet natural grass, SG (soft ground) specific boots might be more suitable.

This is common with new boots. Ensure your socks are appropriate (moisture-wicking, not too thick). Allow for a proper break-in period. Use athletic tape or blister prevention products on prone areas until the boots are fully molded to your feet.

Always air dry boots naturally, away from direct heat. Stuffing them with newspaper after cleaning can help absorb moisture and retain their original shape. Avoid leaving them in hot cars or direct sunlight for extended periods.

The collar is designed for a secure, adaptive fit. Ensure you are pulling it up correctly. If it feels too tight, it may loosen slightly with wear. If it feels too loose, your foot might not be properly seated or the boot size could be incorrect.
