The PULSEâ„¢ Line is the thinnest Swiftwick sock. The PULSEâ„¢ is engineered with our patented antimicrobial silver-ion bonding process that is activated when you sweat, eliminating odor-causing bacteria. Our Managed Compressionâ„¢ supports all 3 arches in the foot while using Linked-Toe technology, eliminating the toe seam for a no bunch toe-box.
