Ultraz Winter Socks - Black

The Ultraz Winter Socks in Black sit near the cold end of ASSOS's endurance sock ladder — a step below the standard Winter Socks in temperature rating, and one rung above the wool-heavy Ultraz FUGU. They are built as an insulated, moisture-wicking winter sock with a compression fit, seamless construction and reflective detailing: the pick for cold training days when a race-tier sock is not enough.
