Aluminium SG Football Studs 8 × 17 mm 4 × 19 mm – New Balance / Mizuno / Umbro / Diadora / Under Armour

When conditions get extreme, millimeters matter

8 × 17 mm in the forefoot and 4 × 19 mm in the heel is not a standard configuration. These lengths are designed for soft, professionally prepared natural grass and intense rain conditions where maximum traction is essential.

On soaked or loose turf, shorter studs often lose effectiveness. The 19 mm rear studs anchor the heel deeper into the ground, delivering stability during braking and sharp directional changes. The 17 mm forefoot studs allow explosive acceleration without sacrificing balance.

Why 17 mm + 19 mm?

• Deep penetration into soft natural grass
• Confident first step in heavy rain
• Stable braking during aggressive turns
• Improved balance in physical duels
• Professional Soft Ground (SG) specification

Details that win matches

Picture the 85th minute. Wet pitch. Sprint toward the ball. With the correct stud length, your movement stays stable and controlled. Your opponent slips slightly — and that fraction of a second can change everything.

Matches are often decided by small technical details: stud length, heel stability, traction during braking. When you are prepared for extreme conditions, you gain an advantage before the duel even starts.

Q&A

Are 19 mm studs considered very long?
Yes. 19 mm is designed specifically for soft, wet natural grass and extreme weather conditions.

Are they suitable for hard ground or artificial turf?
No. These are Soft Ground (SG) studs intended exclusively for natural grass surfaces.

Will I really feel the difference?
Absolutely. The difference is most noticeable during acceleration, braking and sharp turns in wet conditions.

Why does stud length matter so much?
In extreme conditions, even a few millimeters determine grip depth, stability and control — especially in decisive match moments.
