Engineered for serious resort days, the Function X delivers the performance snow socks demand. This midweight merino wool construction balances breathability with insulation, keeping your feet comfortable from first run through afternoon laps. Strategic terry cushioning along the shin and across the foot's arch maximizes warmth without bulk, while reinforced heel construction withstands the repetitive impact of back-to-back runs. The over-the-calf design ensures consistent coverage and support, making these the technical choice for skiers and riders who refuse to compromise on comfort.
