Nike Mercurial Superfly 9 Club KM Football Boots - Brown - Green - 2.5

These are primarily designed for firm ground (FG) natural grass. While they may work on some artificial surfaces, FG boots can lead to increased stud pressure on certain turf types.

The boots follow standard UK children's sizing. It is recommended to leave about half an inch of space at the toe for comfort during rapid movement.

No, machine washing can damage the adhesive and material structure. Always clean them by hand.

The stretch-knit collar is designed to be form-fitting and does not have laces or straps to adjust the tension; it relies on the elasticity of the knit material.

No, the Nike Mercurial Superfly 9 Club KM is designed as a unisex model for all young players.

Ensure the knit collar is fully stretched before putting your foot in; if it remains uncomfortable, wear thinner sports socks.

Use a specialized boot brush or a dull plastic scraper to clear debris after every session to maintain grip.

Wipe away dirt immediately after play. While scuffs are common, cleaning prevents dirt from grinding into the material over time.
