Mountain Heritage Microweight Merino Wool Crew Liner Socks
The sock that does everything without getting in the way. The Mountain Heritage Microweight Crew Liner Socks deliver 58% merino wool performance in an ultra-thin, barely-there design that works year-round. The crew height—the most common sock height—sits comfortably at the bottom of your calf, protecting against boot rub while staying invisible under your pants. Wear them solo for a minimal feel during summer hikes, layer them under cushioned socks for winter warmth, or slip them on for everyday comfort. The Y-heel construction creates a perfect pocket for your heel, so they stay put whether you're traversing a peak or running errands.
Why You'll Love These Liner Socks
- Ultra-Thin Liner Design: No cushion, no terry—just a minimal sock that feels like a second skin for barely-there comfort
- True All-Season Versatility: Light enough for summer hiking, effective as a base layer for winter layering—these work spring through winter
- Y-Heel Construction: Creates a perfect pocket for your heel, eliminating slip and bunching throughout the day
- Protective Toe Bumper: Light padding at the toe shields against toenail pressure without adding bulk
- 3-Zone Elastic System: Elastic at the arch, ankle, and welt opening keeps the thin fabric snug and wrinkle-free
- Vented Top-of-Foot Design: Mesh ventilation zones release heat and moisture for cool, dry feet
- Reinforced High-Wear Areas: Heel and toe plating extends durability even in thin construction
- USA Made Quality: Crafted in New Hampshire using wool/nylon yarn technology for durability with high merino content
