The Nike Mercurial Superfly 9 Pro is the second-tier Pro model in the Mercurial speed lineup, positioned below Elite but above Academy and Club. The Mercurial Superfly 9 Pro delivers near-top performance for ambitious amateurs and semi-pro players who want match-ready speed without stepping into the highest tier of soccer cleats.
The Superfly 9 Pro FG configuration is built specifically for firm natural grass. These firm ground cleats are optimized for short, dry natural grass pitches and are not designed for artificial grass or turf.
The Mercurial Superfly 9 pro prioritizes speed, controlled responsiveness, and practical durability. Compared to Elite, it features an all-new Zoom Air unit in the heel. This air zoom configuration provides an additional level of springy underfoot feel that helps you move and create separation when it matters the most - whether you're scoring goals or chasing down a defender.
The structure is made of a thin but strong material that secures the foot. The speed cage inside of the structure is made of a thin internal frame. This strong material that secures the foot to the outsole without adding bulk helps transfer energy underfoot. The result is a more contoured toe box and better lockdown for quick directional changes.
Compared to the Academy, the Pro tier offers more advanced materials and a more responsive plate. It is built for players who train regularly and compete in organized soccer matches, not occasional sessions.
The Nike Zoom Mercurial Superfly 9 pro firm-ground is a strong choice for:
Speed wingers and forwards who rely on acceleration
Full-backs who need to move faster on the field
Players who want a collar that provides an additional level of ankle containment
Athletes playing primarily on firm natural grass
For match and training use, this cleat is versatile. It handles frequent weekly sessions and competitive soccer game demands on firm grass. Rotating pairs can extend longevity if you train on harder surfaces, but this model is built to manage consistent use across a full season.
On dry or moderately moist natural grass, the FG configuration provides optimal bite for sprints, cuts, and braking. It is not intended for soft, muddy pitches and should not be used on rubber-crumb artificial grass.
On firm natural grass, the mercurial superfly 9 pro firm-ground feels responsive and stable. The articulated plastic plate works with the heel Zoom Air unit to provide a level of springy underfoot feel that helps you move fast during toe-off without feeling overly rigid.
The Tri-Star stud pattern mirrors the traction layout used across higher tiers. On firm, dry grass, these studs grip cleanly during acceleration and help create separation when it matters. Braking feels predictable when stopping or cutting back toward goal.
Over repeated sessions on firm ground, the structure holds up well. The synthetic upper and plate are durable enough for a full recreational or competitive soccer season. It generally outperforms Academy in long-term consistency while trailing Elite slightly in refinement.
The FG studs are shaped and spaced for natural grass penetration. They are too aggressive for artificial grass. Using them on AG surfaces can feel unstable and may increase stud pressure on harder fields.
The Pro tier uses a Vaporposite+ synthetic mesh upper with textured chevrons for grip on the ball. The speed cage inside supports the foot and helps provide a secure feel during sharp cuts.
Ball contact feels direct and controlled. Passing and shooting feel clean without excessive padding. The pliable upper helps create a close-fitting feel without stiffness. Compared to Elite, the Pro upper is slightly more flexible, but performance remains high for competitive soccer cleats.
The collar is made of soft, stretchy fabric that wraps the ankle comfortably. This design helps reduce stiffness out of the box and improves lockdown during high-speed movement.
On firm grass, the stable platform enhances touch during high-speed dribbling. Because FG provides solid ground penetration, the upper can perform as intended without slippage underfoot. The Nike Mercurial Superfly 9 Pro FG soccer cleats are built to dominate fast-paced moments and help you move faster on the field and create separation.
All Superfly 9 tiers share the same speed-focused DNA within the Mercurial line. The model emphasizes acceleration and agility in the modern soccer game.
The Superfly Pro adds collar support compared to Vapor for players who prefer added ankle structure and a more secure feel.
Compared to Elite, Pro feels slightly less responsive underfoot due to the heel-only Zoom Air unit and a more streamlined plate. However, it still provides excellent air responsiveness for its tier.
Compared to Academy, Pro offers better structure, traction, precision, and durability for frequent training and matches.
Compared to MG, FG is more specialized for firm natural grass. MG models are built to handle both natural and artificial surfaces.
Compared to Turf or Indoor options, FG soccer cleats are built for outdoor natural grass fields.
FG Tri-Star studs provide strong bite and rotational freedom on firm grass. They are not suitable for soft, wet ground.
Choose this cleat if you:
Train multiple times per week on firm natural grass
Play competitive soccer matches
Want a fast, responsive feel underfoot
Need near-Elite performance without the top-tier price
This model is built for the attacking player who wants to dominate wide areas, beat a defender, and focus on scoring goals.
If you mainly play on artificial grass, an AG or MG version will provide better traction. If you want the most responsive Nike Mercurial available, Elite remains the top option.
More spacious and flexible than Elite
Stretchy fabric collar suits normal to slightly wide feet
True to size for most players
Synthetic upper softens after one to two sessions
Low blister risk after short break-in
The Pro version provides a slightly roomier feel while maintaining lockdown and structure.
Surface-specific traction matters. Stud shape and length directly affect grip, stability, and comfort.
FG stands for Firm Ground. It is intended for short, dry natural grass pitches and stable fields. The studs penetrate natural grass to provide optimal multidirectional traction.
Do not use FG on artificial grass, soft muddy fields, or carpet turf. On harder synthetic surfaces, the studs may feel aggressive and uncomfortable.
Within available FG soccer cleats, this configuration is specialized for natural grass only.
