Darn Tough's Via Ferrata Micro Crew is a perfect addition to any hiker’s quiver of socks. Strong as steel but soft to the touch. Cushioning under foot delivers the ultimate level of comfort from peak to peak. Seamlessly constructed of fine gauge Merino wool, these socks are both durable and irresistibly comfortable. Cool in the summer, warm in the winter and naturally antimicrobial (repelling bacteria and odor)—a great feature on the trail when you need an extra day (or two) out of your socks.
