THORLO'S sokken Thorlo Extreme Cold Max Cushion Crew 43-47 navy

When winter bites hard, ordinary socks surrender—these Thorlo Extreme Cold Max Cushion Crew socks are built to hold the line. The Zeķes line pairs Thorlo's legendary Thorlon® acrylic with a dense, zone-specific cushioning system that keeps feet warm, dry, and blister-free in the most brutal conditions. Unlike generic thermal socks that flatten and chill, this crew delivers maximum cushioning at the ball, heel, arch, and instep, with ventilation channels that actively move moisture away from the skin.

Highlights

• Extreme cold thermal rating for winter sports, hiking, and mountaineering
• Maximum cushioning in ball, heel, arch, and instep zones
• Thorlon® acrylic fiber technology for superior warmth, softness, and durability
• Moisture-wicking ventilation channels keep feet dry and comfortable
• Low-profile flat toe seam prevents irritation and blisters
• Cushioned instep and arch provide targeted support and a secure fit
• Unisex sizing EU 43-47 (US Men's 9-12.5, Thorlo Large)

In daily use

Pull these on before a dawn patrol ski tour or a long day on frozen trails, and feel the difference: the dense cushioning absorbs impact, the arch support reduces fatigue, and the flat toe seam stays smooth inside your boot. The high Thorlon® acrylic content (87%) means they retain warmth even when damp, while the 11% nylon and 2% spandex add stretch and shape retention. Machine wash warm and tumble dry low—they come back ready for the next cold snap.
