Merino 10 is everything you love about Merino, times 10. Feetures united merino wool with Tencel fibers to create a game changing merino sock. This intimate blend of Tencel and wool is spun with a new innovative technique which results in a sock that is comfier, drier, stretchier, and tougher. High density cushioning in all the right places to provide impact protection with every stride. Quarter height hits just above the ankle to keep debris out of your socks. Anatomical right and left foot design enhances fit to help to eliminate blisters and other foot abrasions. Perfect Toe construction eliminates any irritating seams across your toes. Merino fibers wick moisture to keep feet dry and odor-free. Merino insulates when wet -- keeping your feet warm in wet, cool conditions. Power Arch provides targeted support where it is needed most.
