Jobst forMen - Men's Full Calf 30-40mmHg Compression Socks are used to treat deep vein thrombosis, chronic venous insufficiency, severe varicose veins, and more. They feature a ribbed design that resembles dress socks and provide graduated compression to different parts of the leg. The top of the stocking has a comfort band to hold it in place throughout the day, yet will not bind or pinch skin. The wide toe with a flat seam allows for a comfortable fit. There is an anti-bacterial additive that reduces odor, while the soft microfibers keep feet cool and dry.
