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 2 pairs of knee high socks featuring a pattern of fine stripes set against deep black and charcoal backgrounds. The yarn blend relies on 70 percent cotton combined with 22 percent nylon and 8 percent elastane for stretch. A mechanical profile delivers 20-30 mmHg of graduated compression, meaning pressure is highest at the ankle and eases as it reaches the top band. The dark ribbed styling coordinates neatly with work trousers or casual shoes.

The 70 percent cotton base produces a soft surface texture across the foot and lower leg. Combined with nylon and elastane, the fine striped knit maintains steady tension without sagging. Because dark charcoal and black cotton attract visible lint in the wash, laundering them inside out helps preserve the sharp lines of the pattern.
Rated at 20-30 mmHg, this firm pressure profile offers significantly more resistance than mild 15-20 mmHg garments. Getting the dense weave past the heel requires strong hands and steady gathering. Using rubber household gloves or a sock donner makes pulling the fabric up the lower leg much simpler.
The Small-Medium size corresponds to shoe sizes from 4.5 to 7.5 and calf circumferences measuring 10.5 to 13.5 inch. Accurate measurements around the widest point of the calf ensure the top welt rests beneath the knee without rolling or biting into the skin.

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.
