PRODUCT DESCRIPTION NuVein thigh length open-toe medical style compression stockings are made in the USA. Classic unisex fit for Men and Women puts healthy legs first. Therapeutic graduated compression helps restore proper blood flow and circulation. Made to hospital grade standards and suitable for everyday wear, NuVein relieves common vein conditions associated with age, lifestyle, or even just sitting or standing for long periods of time. NuVein hosiery can be worn by adults of all ages to treat and prevent cardiovascular stress, and helps manage common symptoms like: tired restless legs, aching sore muscles and feet, or heavy feeling in extremities and toes. Rated "Extra Strength" (heavy pressure elasticity) the 20-30 compression level is measured in "mmHg" a unit of pressure, which indicates how tight the garment will feel. A 20-30 mmHg compression level is suggested for use when recommended by a doctor or health care provider specifically for vascular disease patients suffering from: DVT, Edema, Varicose Veins, Spider Veins, Sclerotherapy in Lymphatic System, Laser Vein Ablation, Thrombosis, and EVLT Endogenous Radiology. Always confirm the correct compression strength prior to purchase. Increg compression strength will impact application and feel tighter (if the garment is difficult to apply it does not mean the size is incorrect, most likely, this signals the incorrect level of compression). NuVein medical style hose are knit with a durable opaque fabric that conceals topical bulging veins. Closed toe options have an oversize toe box meant to allow increased movement of toes, and ensure sensitive conditions such as hammer toes, blisters, bruising, bunions and corns are not irritated or compressed together. The ideal use case is users needing a medical product for recovery and optimal circulatory health. Open toe models allow easy toe inspection and permit a standard size to fit a variety of foot length dimensions. Measure when swelling is at a minimum. Sold in pairs.
