The Hike Plus Medium Crew socks are durable, breathable, and odor-resistant socks for all-round hiking and backpacking. The fully cushioned, quick-drying design is anatomically sculpted for premium fit and comfort, with key support zones in the ankle, Achilles, and instep. Reinforcements in the heel and toe increase durability, while the seamless toe reduces bulk and prevents blisters. Inspired by nature, icebreaker harnesses the performance qualities of natural fibers to offer an alternative to clothing based on petrochemical synthetics. Merino is an annually renewable fiber that naturally resists odors, keeps you cool when it's hot and warm when it's not, and lets your skin breathe for comfort all day, every day.
