Ultra-thin Merino ski socks designed for tight-fitting boots, zero bulk, and all-day breathability on the mountain. The Smartwool Ski Zero Cushion Over the Calf Socks are built for skiers who demand precision, comfort, and minimal bulk inside performance ski boots. With a non-cushioned, slim profile, these socks create a breathable barrier between your foot and boot while maximizing control and feel. Constructed with a Merino wool blend, they regulate temperature naturally, wick moisture efficiently, and resist odor during long days on snow. Body-mapped mesh zones increase breathability where heat builds up most, helping keep feet dry and focused from first chair to last run. Smartwool’s 4 Degree™ elite fit system ensures a secure, performance-oriented fit that eliminates bunching and hot spots. Indestructawool™ technology reinforces high-wear areas for long-term durability, while Shred Shield™ reduces toe wear from repeated friction inside rigid ski boots. A wider welt at the top keeps the sock comfortably in place over the calf without cutting off circulation. Made in the USA with imported yarn, the Ski Zero Cushion Over the Calf Socks are ideal for resort skiing, backcountry laps, and any scenario where boot fit and precision matter more than padding.
