Boasting handsome, versatile style, the Sockwell Circulator Argyle compression sock helps increase blood flow, decreases swelling and delivers excellent support. The gradient compression of this men's tall sock is greatest at the ankles and gradually decreases toward the top; blood pushes upward toward your heart, maximizing circulation. Moderate (15 - 20 mmHg) compression is recommended for all day and every-day wear, prolonged sitting or standing, travel, exercise and recovery and minor to moderate swelling. The wool/ nylon blend fabric balances durability and thermoregulation properties with naturally antimicrobial and luxurious bamboo, while a touch of spandex ensures a snug fit and helps prevent slipping. The Sockwell Circulator Argyle graduated compression sock is finished with a seam-free closure at the toe to reduce irritation.
