This pack contains 4 pairs of plain black knee highs knit from 60 percent cotton, 32 percent nylon, and 8 percent spandex. The deep black shade stays uniform under work trousers or dark scrubs, though it will pick up light-colored carpet lint over time. A firm mechanical rating of 20-30 mmHg provides strong hold, starting tightest around the ankle and decreasing toward the calf band. The natural yarn gives the leg a matte appearance rather than the sheen of plain synthetic hosiery.

The 60 percent cotton base produces a soft, breathable barrel that remains opaque across the lower leg. Blended nylon adds resilience across the heel pocket, while 8 percent spandex maintains consistent tension across the leg. The all-black yarn avoids pattern lines entirely, making daily rotation simple across the full set.
A true 20-30 mmHg knit offers substantial resistance compared to lighter hosiery. Pulling these socks over the heel takes deliberate effort and two hands. House gloves with rubber palms or a standard wire donner simplify gathering the foot section and smoothing the fabric up to the knee.
The X-Large profile accommodates a US shoe size from 9 to 13.5 and calf circumferences measuring 16 inch to 19 inch. Taking an accurate calf measurement around the widest point ensures the upper ribbed cuff rests flat below the knee bend without rolling down.

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.
