Embrace the most demanding terrains and coldest climates with the icebreaker Merino Women’s Hike+ Heavy Crew Socks. Specially engineered for long-distance backpacking, rugged trekking, and cold-weather hiking, these socks combine the natural thermal properties of premium Merino wool with an advanced, anatomical fit. With maximum cushioning and zones designed specifically for high-impact protection, they act as a reliable barrier against blisters, friction, and freezing temperatures—ensuring your feet stay comfortable from the first mile to the last.

Specifications

• Item Number: #0A578L

• Material Composition: Premium Merino Wool blend (optimized with Nylon for durability and LYCRA® for stretch)

• Cushioning: Heavy / High-density

• Height: Crew (sits just below the calf; ideal height for standard mid-to-high hiking boots)

• Features: Breathable mesh zones, Achilles support, seamless toe, reinforced heel and toe.

Key Technical Features

• Anatomical Left/Right Fit: Unlike generic socks, these are knit specifically to match the distinct contours of your left and right feet, eliminating excess fabric and bunching that lead to blisters.

• Heavyweight Full Cushioning: Maximized padding throughout the sole, heel, and shin absorbs high-impact shock from heavy backpacking loads and rugged, rocky trails.

• Merino Wool Moisture & Odor Control: Naturally breathable and moisture-wicking, Merino wool moves sweat away from your skin while inherently resisting odor-causing bacteria—keeping your boots fresh for days.

• Achilles & Instep Support: Integrated elastic compression bands lock the sock securely around your ankle and arch, preventing it from slipping down or shifting inside your footwear.

• Seamless Toe Closure: A completely flat, seamless toe box eliminates bulk and friction in the toe zone, preventing painful pressure points on steep downhill descents.

Care Instructions

• Washing: Machine wash warm or cold inside-out with similar colors. Use a regular gentle cycle.

• Detergent: Use a mild liquid detergent. Avoid fabric softeners and bleach, as they coat the natural wool fibers and destroy their moisture-wicking abilities.

• Drying: Line dry in the shade for longevity. If you must use a dryer, tumble dry on low heat only.

• Do Not Iron: High heat will scorch the delicate wool fibers and melt the elastic elements.

Professional Tips from X-Boundaries

1. The Multi-Day Expedition Secret: Because Merino wool is naturally antimicrobial, these socks resist odor for days. On week-long expeditions, you only need to pack 2 or 3 pairs—wear one, air out the other, and save massive space in your pack.

2. The Perfect "Boot Match": These heavy-cushioned socks occupy a bit more volume inside your shoes. They are perfectly suited for stiffer, full-leather backpacking boots or alpine footwear, helping to dial in a snug, secure fit.

3. Temperature Regulating: Don't let the "heavy" label fool you. Merino wool regulates temperature dynamically; it traps warmth in freezing alpine environments but breathes exceptionally well to prevent overheating if the sun breaks out.

4. The "Dry Camp" Sock: Always keep one dry pair of these socks safely tucked away inside a dry bag exclusively for sleeping at night. Slipping into fresh, heavy Merino socks at camp instantly warms your core temperature.
