The N-Ferno 6494 Freezer Socks are crafted from a merino wool blend, specifically designed to deliver superior warmth and protection in cold to extreme cold conditions. Natural insulating properties of Merino wool help retain heat without overheating for winter hikes or frigid work environments. Increased length offers extended coverage, ensuring full-length insulation that protects not just the feet but also the lower legs from cold temperatures. Breathable and moisture-wicking design pulls sweat away from the skin to keep feet dry and comfortable. Arch support band helps reduce foot fatigue by offering a snug, supportive fit that promotes stability. Reinforced heels and toes add extra durability where it's needed most, helping the socks withstand frequent use and rough conditions. Socks are ideal for anyone working on cold storage facilities or participating in outdoor activities in the cold.
