Why Do Soccer Players Use Trusox? The Grip Sock Explained

Have you spotted those socks dotted with tiny rubber bumps peeking above footballers' boots? They're called Trusox, and they've quietly revolutionised how players move on the pitch. TL;DR: Soccer players use Trusox because their grip-dot technology stops the foot from sliding inside the boot, improving control and reducing blisters.

What Are Trusox?

Trusox (pronounced “true socks”) are performance grip socks worn by footballers under their boots. Each sock carries small TPU (thermoplastic polyurethane) nubs on both faces — the inside grips your foot, while the outside grips the boot's interior.

The brand was launched in 2016 by British entrepreneurs Billy McNeill and Andy Rossiter, who adapted grip technology used in other sports and made it football-specific.

Why the Grip Matters

A foot that slides inside a boot loses power and precision. Trusox keep everything locked in place so touches stay sharp, turns stay clean, and shots land sweetly.

Not Just Comfort — Performance

Players report three key benefits:

• More control — the foot stays planted, so first touches and dribbling feel more reliable
• Fewer blisters — less friction means less skin damage during long matches
• Better stability — especially in wet or muddy conditions where sliding is common

Many top professionals now wear them, including Cristiano Ronaldo, Harry Kane and Erling Haaland. They became a common sight in the Premier League after FIFA approval. Learn more about the technology.

Are They Just for Pros?

No — Trusox and similar grip socks are available to everyday players at every level. Whether you play Sunday league or five-a-side, the same anti-slip benefits apply. Most football equipment retailers now stock them. See how far the grip-sock trend has spread.
