Our newest model of ultra-insulating winter socks, designed with a wool-blend fabric and reinforced with even more protection from the cold where it matters most. Warm, breathable and ultra-soft: maximum comfort even in the harshest winter conditions. The Ultraz FUGU cite the warmest and most protective winter gear line in ASSOS history, a perfect name for our most thermoregulating sock pattern ever. The wool blend creates micro-bubbles of warm air under the protective layer of the shoe cover, increasing thermal insulation at the toe and front of the sock. The ultra-high 31 cm border extends the protection to eliminate transition zones between the FUGUs and the winter sock.
