Merino wool socks are extremely popular due to their softness, comfort, and durability. These socks are made with finer, softer wool for a better quality sock. To choose a pair, find a pair that is softest and most comfortable to you. You'll also want to see if they are moisture wicking, absorbant, and able to reduce odors using bacteria-resistant fibers. All of these factors go into making a great pair of merino wool socks.
