*WIDE CALF DESIGN- Extra large wide calf size, premium elasticity fabric built for durability. Special design for women and men with extra large or plus size. More comfortable than standard compression socks, these big and tall calf compression socks provide strong leg support and long lasting graduated compression, as well as ultra comfortable wear with lightweight and breathable materials. *MORE SIZE CHOICES- Plus sizes available (S-7XL) for ankle up to 14 inches, calf 16 to 24 inches circumference. Please refer to the size chart to choose the appropriate size (in general, we suggest selecting the larger size if you are between two sizes). These knee-high compression socks offer snug, supportive fit without being too tight and help enhance blood circulation effectively. *QUALITY & COMFORT- Constructed from durable nylon fabric for comfort and longevity. The stretchy yet strong fibers make the socks easy to put on and take off. They fit securely from toe to knee, promoting energized legs. A comfortable wide top band prevents rolling and provides 360-degree stretch for greater flexibility and durability. Breathable high-performance fabrics help maintain optimal temperature and wick moisture away from the skin to keep you feeling fresh and comfortable. *COMPRESSION THERAPY INNOVATION- These compression socks (20-30 mmHg) feature graduated compression with varying pressure gradients from bottom to top, promoting smooth blood flow from the lower legs upward. Improved circulation helps support healthier legs and reduce pain and swelling. Graduated Compression Stockings help reduce fatigue, soreness, cramping, and swelling, support muscle recovery, and assist with varicose veins. *HIGH PERFORMANCE + SUITABLE FOR DAILY WEAR- Compression socks are designed to support performance, aid in recovery, and provide relief from discomfort and inflammation. They offer optimal muscle support and are ideal for individuals who spend long hours on their feet, as well as those active in sports and fitness. Suitable for joggers, athletes, fitness enthusiasts, office workers, parents, grandparents, runners, nurses, and healthcare professionals.
