NuVein Compression Socks for Men. Made in the USA. Designed as a men's everyday fashionable dress sock for stylized casual or formal business wear. Microfiber nylon stretch for increased comfort in all seasons. Easy on application and easy off removal. Ultra soft and smooth rib knitting with low profile filament and flat irritation free toe seam fits inside designer shoes, boots, loafers and sandals. NuVein support stockings and compression hosiery use therapeutic graduated compression to restore blood flow and circulation. Designed to hospital grade standards for practical everyday wear, NuVein relieves common vein conditions associated with age, lifestyle, or even just sitting or standing for long periods of time. NuVein is suitable for adults of all ages to treat and prevent cardiovascular stress and help manage common symptoms like: tired restless legs, aching sore muscles and feet, or heavy feeling in extremities and toes. NuVein is available in "Medium Strength" compression. Compression strength is measured in "mmHg" pressure, which indicates how tight the garment will feel. Choose 15-20 mmHg (medium strength) compression to revitalize legs with discomfort, swelling, bulging, or blood clots (fluid buildup post surgery). Travelers who experience "economy class syndrome" or "jet leg" should wear 15-20 mmHg, as well as athletes post training to aid muscles and tissue recovery. Medium 15-20 strength is the common starting point for first time wear. NuVein hose feature classic styling and a breathable opaque smooth fabric that conceals topical bulging veins. Closed toe options will not compress or bind foot when worn in shoes. Measure when swelling is at a minimum. Sold in pairs.
