Bridgedale Socks: Men's Endurance Summit Knee Socks

Tested and recommended by GORE-TEX® labs for hiking shoes and climbing boots equipped with GORE-TEX® textiles, the Bridgedale Expedition Summit Sock is comfort rated to -13F (-25C). The design is very similar to Bridgedale's bestselling Summit sock, but the Expedition Summit Sock has a special Y-heel and anatomic foot shape, extra length and plenty of double-density padding under the foot. This is a design developed for extended wear in those cold spaces where the nearest warming hut or refuge is hundreds of miles away. Whether you're trekking into uncharted territory or just looking for gaiter-length warmth for your winter backcountry fun, the Bridgedale Expedition Summit Sock is one of the best for cold weather protection.

• Entire sock fabric consists of 47% new wool/34% nylon/18% Isolfil/1% Lycra®
• Gaiter-length coverage (longer than Bridgedale's best-selling Summit sock)
• Extended cuff has special calf grip for hold
• Warm, impact-absorbing fabric padding with dual-density fabric under foot
• Stretchy Lycra ankle and arch support with forward flex zone
• Y-heel and anatomic foot shape
