Mountain Heritage Microweight Merino Wool Cushion Boot Socks

Your favorite boots deserve a sock that works just as hard. The Mountain Heritage Microweight Cushion Boot Socks from Minus 33 deliver full footbed cushioning in a surprisingly lightweight package—microweight fabric that won't add bulk but still provides all-day comfort underfoot. With 61% merino wool content and USA manufacturing in New Hampshire, these socks combine heritage textile craftsmanship with performance features that keep feet dry and supported from dawn to dusk.

Why You'll Love These Merino Boot Socks

• Full Cushion, Minimal Weight: Complete footbed padding wicks moisture and absorbs impact without the thickness of heavier socks—perfect for all-season wear in boots
• 3-Zone Elastic System: Elastic at the arch, ankle, and welt opening keeps socks in place throughout long days without slipping or bunching
• Vented Top-of-Foot Design: Mesh ventilation zones release heat and moisture, preventing feet from overheating inside boots
• Reinforced High-Wear Areas: Heel and toe plating extends durability where boots create the most friction
• Seamless Toe Construction: Smooth finish eliminates pressure points and irritation for blister-free comfort
• USA Made Quality: Crafted in New Hampshire using wool/nylon yarn technology that maximizes merino content while maintaining durability
