Essential Opaque Knee High 30-40mmHg Open Toe

Why Choose Sigvaris Essential Opaque Knee High 30–40 mmHg Open Toe

Extra-firm compression at 30–40 mmHg is prescribed when lower classes have proven clinically insufficient — significant oedema, advanced venous insufficiency, varicose vein management beyond what 20–30 mmHg addresses, and long-term venous stasis presentations. The Essential Opaque delivers this pressure in the most practical knee-high format: easier to apply than thigh-highs, more compliance-appropriate for daily self-managed therapy, and available in the widest size range Sigvaris produces — including short, long, petite, and plus sizing — to ensure accurate gradient delivery across diverse patient body types. The durable nylon/spandex opaque knit is specifically chosen for this compression class because it maintains compression integrity through the repeated daily laundering that 30–40 mmHg patients require, unlike lighter sheer fabrics that fatigue faster under sustained pressure. Open-toe design relieves forefoot pressure for users with bunions, wide forefeet, or toe sensitivity, allows visual skin inspection that is clinically important at extra-firm compression levels, and accommodates a wider range of footwear. Black and Light Beige options. Latex-free. Prescription required — clinical fitting essential.

Usage & Care

Don stockings in the morning before rising — 30–40 mmHg requires application when legs are least swollen. Use a donning glove; extra-firm compression requires careful application technique to protect the garment and ensure correct gradient positioning. Smooth evenly from the foot to the knee-high cuff with no bunching. Machine wash on gentle cycle in cool water with mild detergent; hang or lay flat to dry. Do not tumble dry, bleach, or iron. Replace every 4–6 months or when compression or elasticity diminishes. 30–40 mmHg requires prescription — confirm size, length, and toe style with a qualified healthcare provider before dispensing.
