40 Below II

The Wigwam 40 Below II socks are a staple for anyone who spends serious time outdoors when temperatures drop. These aren't your lightweight trail runners; they're built for substantial warmth and comfort in truly cold conditions. Wigwam typically constructs these with a significant percentage of wool, often merino or a blend, which is crucial for insulation, moisture management, and odor resistance – all non-negotiables when you're layered up and moving in the cold. The high-density cushioning throughout is noticeable, providing a plush feel that not only adds warmth but also helps prevent pressure points when worn with stiffer winter boots. They maintain their loft and cushioning well over time, even after repeated washes, which speaks to their robust construction.

In the field, these socks perform reliably. While the exact blend can vary, the wool content ensures they pull moisture away from the skin, a critical factor in preventing cold feet. Even when damp from perspiration or a little snow ingress, they retain much of their insulating properties, a characteristic synthetic fibers struggle to match. The fit is generally snug and supportive, preventing bunching that can lead to blisters, especially important when you're covering significant distances. Their thickness means you might need to size up your boots slightly if your typical hiking socks are much thinner, but the warmth payoff is worth it.

Compared to lighter or more performance-oriented merino blends, the 40 Below II prioritize sheer warmth and durability. They're thicker, heavier, and less compressible than a pure merino ultralight sock, but they're also designed for a different purpose entirely. For dedicated winter hikers, snowshoers, ice fishers, or anyone working in frigid environments, these socks stand out as a dependable, long-lasting option that delivers on its promise of keeping your feet warm when it truly matters. They're a classic for a reason, offering honest performance without overcomplicating things.
