These solid black knee highs provide firm 20-30 mmHg mechanical tension in an understated shade that fits medical scrubs, work trousers, or dark boots. The knit is 80% viscose made from bamboo, blended with 17% nylon and 3% spandex for structured stretch. Pressure starts strongest at the ankle and eases upward below the knee. Each pack includes 4 pairs for a steady weekday routine. The deep black finish looks clean under formal footwear but will catch light-colored pet hair and laundry lint.

The 20-30 mmHg rating delivers firm compression along the lower leg. It sits tightest around the ankle and tapers toward the upper calf band. Because this grade offers noticeable resistance, donning requires two hands or rubber donning gloves to smooth the fabric past the heel.
The yarn blends 80% bamboo viscose with nylon and spandex, creating a smooth surface against sensitive skin. Solid black hides scuffs from dark work shoes and matches standard uniform requirements. The dense dark dye requires basic machine washing without bleach to keep its deep shade.
This Medium size fits US shoe sizes 7 to 9 and accommodates calf circumferences from 12 to 16 inch. Measure the widest part of your calf before choosing your size. If your leg measurement sits past 16 inch, the upper band can press too deeply into the skin by the end of a shift.

Compression comes from spandex under tension. Heat relaxes spandex permanently, so the two things that kill a compression sock are a hot wash and a hot dryer. Nothing else comes close.
