Assos Ultraz FUGU Winter Socks - black series

An all-new, ultra-insulated winter sock platform, engineered with a wool textile blend and reinforced with increased insulation in critical areas. Breathable, ultrasoft, and warm – total comfort for winter’s harshest conditions.

The Ultraz FUGU hearkens back to the warmest, most protective line of winter equipment in ASSOS history, so it’s fitting to bring back for our most thermoregulating socks. The wool blend creates micropockets of warm air beneath the protective layer of your booties, with increased insulation across the toe and the front of the sock. The ultra-high 31cm (16in) cuff extends that protection to eliminate gaps between the FUGU and winter tights.

Features of the Assos Ultraz FUGU winter socks

• The breathable, thermoregulating wool blend textile combines high elasticity with proven insulation that stays warm, even when wet.
• 160 needle construction eliminates seams and wraps in lightly compressive support, preventing slumping or restrictive pinching. Increased insulation on critical areas and an extended cuff height add warmth for winter’s harshest conditions.
