Therafirm has released 3 new patterns to its Patterned Core-Spun line of compression socks. Monogradient is a sock with white, gray, and black stripes. Slate argyle is a traditional argyle pattern in black, gray, and a soft slate color. Pink argyle is an identical sock that trades slate for a soft pink. Core-Spun Patterns are available in three compression levels: 10–15mmHg light, 15–20mmHg mild, and 20–30mmHg moderate support—although not all patterns are available in every compression level. Core-Spun socks are designed to improve circulation, prevent swelling, and energize legs.
