Ultraz Winter Socks EVO

The Assos Ultraz Winter Socks EVO is their warmest winter sock, updated with triple the insulation across the toes and arch.

The key to maintaining warm feet while riding in winter is to combine insulation with the ability to stay dry from the inside and the outside. These socks combine the stretch and moisture-management of synthetics with the superior insulation properties of wool. Compared to its predecessor, the insulation has then been tripled across the toe and up the blue panel beyond the arch, providing extreme warmth for the coldest days.


  • Blend of synthetic fibers and wool that maintains the best qualities of both for a breathable textile with stretch-and-return properties, odor resistance, warmth while wet, and extreme insulation.
  • Seamless construction provides a frictionless fit that wraps the foot in light, compressive support without slumping or restriction at the cuff.
  • Toe and midfoot feature extreme insulation.

Comfortable, good for temps in the 40�s

Look cool, very comfortable, great for temps into the 40�s. But nothing beats merino wool for temps that dip into the 30�s.
