Ultraz Winter Socks P1

What Our Gearhead® Experts Are Saying:

"In freezing temps, these socks are a game-changer. They insulate well, breathe when I start pushing, and the compressive fit keeps my feet feeling strong. They’re durable too—I’ve put them through tough winter miles without any wear issues."

The Assos Ultraz Winter Socks P1 are engineered to perform when conditions are at their harshest, offering uncompromising comfort and thermal control for dedicated cold-weather cyclists. A carefully tuned merino wool and synthetic fiber blend provides warmth while actively managing moisture, ensuring dry feet that stay comfortable across varying levels of exertion.

Construction details enhance both comfort and durability. A seamless knit eliminates irritation and hotspots during long days in the saddle, while reinforced heel and toe zones extend the lifespan of the socks through repeated winter use. The compressive fit not only improves blood circulation but also provides targeted support, keeping feet stable and reducing fatigue during extended training blocks.

Designed with Assos’ precision-driven approach, the Ultraz Winter Socks P1 balance insulation, breathability, and fit in a package that stands up to the demands of extreme winter riding. For cyclists unwilling to compromise on comfort or performance in the cold, these socks deliver the technical edge to keep pushing forward.
