Ultraz Winter Socks - Black

ASSOS socks span the full performance and lifestyle range. Poker Socks 0-9 in Holy White are the signature 10-number lifestyle line, designed to be mixed for lucky-number combinations. Race-tier socks (RSR Speed, RSR Bolide, RS Superleger, RSR Thermo Rain) sit on the race chassis. Endurance-line socks (Spring-Fall, Winter, Ultraz, Ultraz FUGU) run the temperature ladder. P1 is the refreshed platform. Collabs include the BOSS x ASSOS Stripe and Monogram socks, and the EQUIPE R Socks EF (2026 EF Pro Cycling replica).
