Nike Zoom Mercurial Superfly 9 Elite CR7 FG - Blue - UK 6.5

FG stands for 'Firm Ground', indicating that these boots are designed for use on natural grass pitches that are relatively dry and firm.

Clean the pattern gently with a soft brush or a slightly damp cloth. Avoid abrasive cleaners or excessive scrubbing to preserve the design.

The Zoom Air unit is integrated into the sole of the boot and is not designed to be removed.

While technically possible, FG boots are not ideal for artificial turf. The studs can be too aggressive, leading to discomfort, reduced performance, and accelerated wear on both the studs and the artificial surface.

VaporPosite+ is a material used in the upper of the boot that combines mesh and a high-quality synthetic to provide an exceptional touch and grip on the ball, especially at high speeds.

The Flyknit ankle sleeve offers a flexible yet supportive fit around the ankle, creating a sock-like feel that enhances comfort and provides a secure lockdown.

The 'Azulejo' design is inspired by traditional Portuguese tiles, reflecting Cristiano Ronaldo's heritage and paying homage to his cleat history.

Allow for a break-in period. Wearing them for short durations initially can help them mold to your feet. If still too tight, consider if this model is suitable for your foot width.

FG studs are optimized for firm ground. Very wet or muddy conditions may require alternative stud options. Ensure the studs are clean and free of debris.

The VaporPosite+ material is designed for structure and touch. Continued use will soften the material. Apply a leather conditioner specifically designed for football boots if needed, following product instructions.

These boots are not recommended for hard ground or artificial turf due to the FG stud configuration. Using them on such surfaces can lead to discomfort and premature wear.
