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, along with ultra-comfortable wear from lightweight and breathable materials. MORE SIZE CHOICES - Plus sizes (2XL-4XL) available for ankles up to 14 inches and calf circumferences from 16 to 24 inches. 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. Stretchy yet strong fibers make the socks easy to put on and take off. They fit securely from toe to knee and feature a comfortable wide top band that 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, designed to support smooth blood flow from the lower leg upward. Improved circulation may help promote healthier legs and reduce discomfort and swelling. Graduated Compression Stockings help support legs, reduce fatigue and soreness, and may assist in preventing cramping, swelling, and muscle strain, while also supporting muscle recovery and managing symptoms of varicose veins. HIGH PERFORMANCE + SUITABLE FOR DAILY WEAR - Compression socks are designed to support enhanced performance, aid in recovery, and provide relief from discomfort and inflammation. They offer optimal muscle support and joint stabilization. Ideal for individuals who spend long hours on their feet, as well as those active in sports and fitness. Great choice for joggers, athletes, fitness enthusiasts, office workers, parents, grandparents, runners, nurses, and medical professionals.
