Lightweight Trail Performance Inspired by Vermont’s Alpine Lakes

The Darn Tough Willoughby Micro Crew Lightweight with Cushion is a high-performance hiking sock engineered for summer mountain adventures and fast-moving trail days. Named after Vermont’s iconic Lake Willoughby, this sock is designed to handle long miles in warm conditions, offering a perfect balance of lightweight breathability and durable support. The micro crew height sits just above the collar of a standard hiking boot, providing protection against trail debris without the extra heat and bulk of a traditional full-crew sock.

Technical comfort is built into the knit. Using True Seamless™ Toe technology, the Willoughby provides an ultra-smooth, irritation-free fit that eliminates the chafing and pressure points often found in high-mileage footwear. To manage moisture, thermoregulating Merino wool wicks perspiration away from the skin and dries rapidly, helping to prevent blisters and "swamp-foot." Soft terry loops underfoot provide targeted cushioning for shock absorption, while a reinforced Achilles area enhances durability in high-friction zones. Like all Darn Tough socks, it is made in Vermont and Unconditionally Guaranteed for Life.
