The Pursuit Line is the world's first 200 needle compression sock made from all-natural Merino Wool, sourced from farmers in the U.S. Swiftwick's premium-cut fibers create a soft, non-scratchy feel. Linked-Toe technology prevents blisters by eliminating bunching in the toe-box. Combine this with our Managed Compression that supports all 3 arches in the foot, and you have a no-hotspot, blister-free, perfect-fitting sock. The Pursuit Line comes in a variety of colors and cuff-height styles.
