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

Heavy-cushioned mountaineering socks built for extreme cold and high-altitude treks, delivering outstanding warmth, moisture control, and odor resistance through a merino wool blend. The Hike+ Mountaineer Mid Calf provides an anatomical left/right fit, seamless toe closure, and targeted support for all-day comfort under heavy loads.

Advantages

Merino wool naturally regulates temperature, wicks moisture, and resists odor, keeping feet dry and comfortable in freezing conditions. Heavy cushioning absorbs impact on rocky terrain, while strategic ventilation zones prevent overheating during strenuous climbs. Reinforced arch, Achilles, and instep support reduce fatigue and improve stability, and the seamless toe eliminates friction to prevent blisters.
