Built around a single idea: stop slipping.
Most golf socks were never designed for the golf swing. They were designed for feet. Inertia started with a different question — what would a sock look like if it was engineered for the moment your driver meets the ball?
The answer was Premgripp®. Medical-grade silicone, mapped to the pressure points that fire through your downswing, knit into a cotton-poly blend that breathes for eighteen holes and washes like any other sock you own.
The result is a quieter foot, a tighter shoe, and the kind of grounded swing you used to chase on the range. We don't need to tell you that's where speed comes from.
The four systems.
Premgripp® silicone
Strategically placed grip pads lock the foot to the shoe through impact.
Offset footbed
Targets calf nerve endings to support circulation and fight fatigue.
Anti-blister knit
Fully elasticated footbed contours to the arch — no friction, no breakdown.
Lab-tested
Independently tested for sensitive skin. Zero irritation reported.
