Energize your legs with VIM&VIGR Graduated Compression Socks. These socks use integrally-knit graduated compression to apply therapeutic pressure that starts at the ankle and gradually eases above, energizing your legs and reducing swelling. With a 20-30 mmHg compression level, they are ideal for all-day, everyday wear, especially for those who sit or stand for long periods. The high-quality premium nylon and spandex fibers provide sustained compression and help increase circulation of oxygenated blood back to your legs, alleviating achiness and heaviness. These socks are beneficial for people with circulation problems, flight travel, pregnancy, exercise, and extended periods of sitting or standing. They are designed to energize legs, reduce swelling, alleviate achiness and heaviness, and aid in muscular recovery. The specially designed nylon fabric and 400-needle count ensure supreme comfort and flexibility, contouring to your leg and heel for a superior fit. The socks are comfortable and breathable, featuring graduated compression from ankle to calf with a contoured leg and heel for a great fit. The flexible toe pocket ensures comfort without squeezing your toes. Tested and trusted, VIM & VIGR is dedicated to providing everyday relief and developed their legwear in partnership with vascular surgeons and vein clinics. All products are listed with the Food and Drug Administration (FDA). These compression socks are available in Black and 3 sizes: Small/Medium, Medium/Large, and Large/X-Large.
