A solid black knee-high sock knit for work uniforms and understated daily wear. The yarn blends 59% viscose from bamboo with elastic, spandex, and nylon for a smooth finish that glides into boots. Graduated 15-20 mmHg compression holds firmest at the ankle and eases below the knee. The dense black dye hides scuffs well, though the extra terry padding through the sole requires a forgiving shoe.

The deep black shade pairs cleanly with dark work trousers, clinical scrubs, and heavy leather shoes. It shows lint faster than patterned knits, but keeps a uniform look across long shifts. The blend uses 59% viscose from bamboo, 23% elastic, 15% spandex, and 3% nylon, finished with a smooth toe seam to minimize friction.
Full terry cushioning runs along the entire base of the foot to absorb impact inside stiff footwear. This extra knit volume takes up noticeable room inside narrow sneakers or formal dress shoes. The moderate 15-20 mmHg gradient pressure remains strongest across the lower leg while easing upward beneath the top welt.
Size Medium matches US mens shoe sizes 5.5 to 9.5 and womens sizes 6.5 to 10, covering calf circumferences from 12.5 to 17.5 inch. The upper band holds securely beneath the knee, though wearers near the upper calf limit may notice red compression marks after extended wear. Hand wash only to maintain elastic recovery.

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.
