What is
OPTI-STUD®?
Superior grip. Moves with you. Patented by us.
No matter what’s underfoot, our OPTI-STUD® technology gets to grips with it.
OPTI-STUD® matches your movements to press the ground, giving you maximum grip.
Larger studs take the force of impact, acting as brakes. Smaller studs push into the ground for extra support. That keeps you sure and steady – even when it’s sloshy underfoot.
Just like car tyres, the OPTI-STUD® design allows you to stay sure-footed no matter what. And it’s anti-clogging. So mud, soil or rocks won’t get stuck in your soles – your shoes stay grippy.
