Extra thick cotton knee highs, Black
Two pairs of extra thick cotton knee highs in solid black, built with 20-30 mmHg graduated pressure.
4.3 (3,083)calf 10.5-17"

This pack contains two pairs of black knee highs designed specifically for fuller leg proportions. Knitted with 70% cotton, 22% nylon, and 8% spandex, the fabric delivers breathability alongside flexible structure. Graduated pressure runs across five zones from the footbed up to the knee, measuring 15-20 mmHg to stay firmest at the ankle and ease upward. The deep black finish offers a clean look for work boots and uniform trousers, though dark cotton yarn will gather visible pale lint in the wash.

The 4X-Large build accommodates calf circumferences from 24 to 26 inch and US shoe sizes 11.5 to 15.5. A wide top welt anchors the upper edge without rolling down over full calves. You will need two hands to gather the dense knit evenly over the heel.
A blend of 70% cotton with nylon and spandex provides natural softness against the skin while keeping recovery tight. The 15-20 mmHg gradient applies measured mechanical resistance across five distinct vertical zones. The flat toe seam prevents friction ridges inside narrow toe boxes.
Knitted terry loops line the footbed to soften impact across the heel and ball of the foot. This added underfoot depth creates extra volume, meaning these socks fit best in roomier work shoes, sneakers, or wide-fitting boots rather than close-fitting dress shoes.

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.
