Essential Thermo Long Socks
Our warmest knee-high socks feature a functional fabric blend and strategic thermal zoning for durable daily wear.
Made for cozy warmth during cool to cold outdoor activities, these knee-high socks have an optimized blend of three yarns designed with technical zoning, minimal bulk, and reinforced areas for added durability.
Using merino wool and synthetic yarns, these socks use zoned construction to achieve a perfect balance of warmth, breathability, moisture wicking and durability. A double-layer, lofty sole offers protection from the cold, while the open upper foot zone promotes breathability. High-wear areas are reinforced with nylon, and support bands on the arch and toes create a snug, comfortable fit.
