Icebreaker Hike+ Mountaineer Mid Calf Socks Men's Jet Heather/Black

On a cold alpine ascent, every detail matters. These mid-calf socks are built for mountaineers and winter hikers who demand warmth, support, and durability. The heavy cushioning absorbs impact on long descents, while the anatomical left/right fit keeps them from shifting inside your boots.

Key specifications

• 70% Merino wool, 27% nylon, 3% LYCRA®
• Heavy cushioning for maximum comfort
• Mid-calf height
• Seamless toe closure prevents blisters
• Reinforced heel and toe for durability
• Anatomical fit for left and right foot
• Breathable, odor-resistant, temperature regulating
• Machine wash warm, tumble dry low

Why choose it

Merino wool naturally regulates temperature, wicks moisture, and resists odor—keeping your feet dry and comfortable over multi-day treks. The added nylon and LYCRA® provide stretch and shape retention, so the socks stay snug without sagging. Achilles, instep, and arch support reduce fatigue on steep terrain.

Ideal use cases

• Winter hiking and mountaineering
• Snow sports and cold-weather trekking
• Extended backpacking trips
• Everyday cold-weather wear

Good to know

Made with mulesing-free Merino wool, these socks are a responsible choice. They are designed for heavy use in freezing conditions, but also work well for shoveling snow or walking the dog on icy mornings. Available in size L (Large).
