NuVein Sheer Compression Stockings for Women. Made in the USA. Fashionable designer style with 20 denier nylon see through non-opaque knit. Available in "toeless" open toe, or closed toe options. Open-toe is great for warmer climates and to accommodate sandals, peep-toe, flip-flops, and foot thong shoes. Closed-toe resemble dress nylon pantyhose and allow for a traditional fit in boots, heels and evening wear flats or wedges. Constructed with smooth durable yarns and completely latex free. Therapeutic massaging graduated compression helps improve circulation and revitalizes legs with the added benefit of leg shaping and enhanced contouring of ankles, swollen ankles and feet. NuVein sheer styles are 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 should pregnant, expecting or nursing mothers. Commonly used as the starting point for everyday wear, travel, leg health, prolonged sitting or standing, increased blood flow, energy, and recovery from intense training or workout on muscles. Designer compression that heals while it conceals. Always confirm the correct compression strength prior to purchase. Integrated compression technology promotes recovery, circulation, and healthy legs. Ideal for nurses, those experiencing spider veins or varicose veins, or extended periods of inactivity where blood pooling or tingling (falling asleep in limbs) may occur. Package includes one pair.
