Mediven Radiance offers the sheerest look in Rx graduated compression. Woven with Medi-Silk yarn, Radiance is lightweight, and comfortable to wear. A lace-top silicone band keeps the stockings firmly yet comfortably in place and discreet fitted toe and heel complement any shoe style. This stocking provides 20-30mmHg of gradient compression, which helps improve blood flow, prevent edema (swelling), and reduce the discomfort caused by moderate to severe varicose veins. It helps in recovery from sclerotherapy and other post-surgical procedures, and in the prevention of venous ulcerations. Woven from 68% nylon and 32% spandex in the USA.
