Nike Air Zoom Mercurial Superfly X Academy AG - Black - UK 8.5

These boots are specifically designed and optimized for Artificial Ground (AG) surfaces, such as 3G and 4G artificial turf pitches. The unique stud configuration provides optimal grip and stability on these surfaces.

Yes, like most performance football boots, a short break-in period is recommended. Wear them for a few light training sessions to allow the NIKESKIN upper and Dynamic Fit collar to conform to your foot and ankle shape for maximum comfort.

The Zoom Air unit is a responsive cushioning technology integrated into the sole. It provides springy, low-profile cushioning that 'snaps back' upon impact, generating increased energy return to help you feel faster and more explosive on the pitch.

After each use, brush off loose dirt. Wipe the upper with a damp cloth and mild soap if necessary. Allow them to air dry naturally at room temperature, away from direct heat or sunlight. Do not machine wash or tumble dry.

NIKESKIN is a lightweight, pliable synthetic material used for the boot's upper. It's engineered to provide a close, comfortable fit that wraps the foot, enhancing ball feel and control while keeping the boot lightweight.

These boots are not recommended for natural grass fields (Firm Ground or Soft Ground). The AG-specific studs are designed for artificial turf and may not provide adequate grip or could be damaged on natural grass, potentially leading to injury or reduced boot longevity.

The Dynamic Fit collar provides a seamless, sock-like connection between your lower leg and foot. It offers a secure, locked-in feel around the ankle, enhancing stability and support during quick movements and directional changes on the field.

Football boots, especially new ones, often require a break-in period. Wear them for shorter periods during light training sessions or warm-ups to allow the NIKESKIN upper to mold to your foot. This will improve comfort over time.

Ensure you are playing on an Artificial Ground (AG) surface. These boots are optimized for AG. If on an AG pitch, check if the surface is excessively wet or dry, which can affect grip. Also, ensure your boots are clean, as mud or debris on the soleplate can reduce traction.

While the NIKESKIN upper is lightweight, some players may experience heat build-up. Ensure you are wearing appropriate moisture-wicking football socks. After play, air out your boots thoroughly and remove insoles to help dry them out.

The Zoom Air unit is designed for durability, but consistent heavy use can eventually lead to a slight reduction in its initial 'springy' feel over a very long period. Ensure your boots are clean and stored properly. If the issue persists with a relatively new pair, consider contacting customer support.
