The Sockwell Graduated Compression Floral Pindot socks have a moderate compression rating (15 - 20 mmHg) to effectively improve blood return from your legs and feet back to your heart. Blood return is proven to speed recovery, maximize circulation, and reduce fatigue. What's most special about Sockwell's Floral Pindot Compression socks is that they not only have a therapeutic function, but are also spun with high-performing and good-feeling merino/bamboo rayon yarns in fresh colors. Floral Pindot socks are actually enjoyable to wear and eclipse that medical feeling that is a side-effect of so many therapeutic socks out there. Refined merino/bamboo rayon yarn improves moisture management, odor control, and temperature regulation so that you are comfortable while you are doing something good for your body, and your sense of style.
