The Swiftwick PURSUIT™ Line is the world’s first 200 needle compression sock made from all-natural Merino Wool. The PURSUIT comes fused with the natural and thermal properties of super fine, 36 micron Merino Wool , sourced from farmers in the U.S. Our premium-cut fibres create a soft, non-scratchy feel. Our 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 cuff-height styles.
