Jobst for Men thigh highs are made of a ribbed fabric with a closed toe and feature a stay-up silicone band that keeps them firmly yet comfortably in place. A reinforced heel resists shoe abrasion, and microfibers wick moisture away from the skin for a dryer, cooler feeling. These stockings provide 20-30mmHg of gradient compression and help improve blood flow, prevent edema (swelling), and reduce the discomfort caused by moderate to severe varicosities. Woven from 71% nylon, 25% spandex, and 4% silicone in the USA.
