Kenetrek Glacier Heavyweight Boot-Height Merino Wool Sock – X-Large

When you need a single pair of socks that can handle a wide range of conditions, the Kenetrek Glacier Heavyweight Merino Wool Sock (X‑Large) is built to perform. This boot-height sock combines rugged durability with soft, itch-free comfort. It dries quickly and holds up under demanding wear, delivering reliable warmth as temperatures drop and breathable comfort when the day heats up. The Merino wool fibers adapt to changing conditions, helping feet stay comfortable through damp mornings and long days on trail or tundra alike.

Key benefits at a glance

• Medium boot-height design provides protective coverage for the ankle and heel
• Incredibly comfortable and itch-free fabric for extended wear
• Reinforced heel and toe pads boost durability and reduce foot fatigue
• Merino wool insulation stays effective even when damp, helping regulate temperature
• Made in the USA for trusted craftsmanship

Beyond comfort, this sock is designed to support active feet. The blend of materials and thoughtful construction can aid in temperature regulation—cooling when you move into shade or a breeze, warming as you climb into colder air—while maintaining a comfortable profile that doesn’t feel bulky. An arch support feature works with the natural shape of the foot to help promote circulation and reduce fatigue during long treks. The design also emphasizes blister prevention, so you can focus on the trail rather than hotspots on your skin.

Real-world outdoor uses

• Snowy mountain hunts where dry feet and steady insulation matter
• Desert hikes or Death Valley treks where quick drying is advantageous
• All-day wear across rugged terrain for reliable comfort
• Cold, damp mornings where insulation remains helpful without overheating
