100% Merino Wool Socks with specifications from the Greek Air Force “Derby Terry M72”. These socks are made from 100% Merino wool, featuring a "derby" knit on the shaft and foot, designed to "hug" the foot without being too tight. They also have a "towel" knit on the Achilles tendon, on the sole up to the top of the toes, providing maximum comfort and protection. The length of the sock shaft exceeds that of military boots, reaching just below the mid-calf.
