Extra thick cotton knee highs, Black

4.2 from 1,055 ratings
$24.991 size

This pack contains 2 pairs of knee highs in solid black, a neutral shade that works under work trousers or dark boots. Built from a 70 percent cotton blend with 22 percent nylon and 8 percent elastane, the knit is thicker underfoot than standard dress socks. The 20-30 mmHg graduated tension stays firmest at the ankle and eases upward toward the knee band. Solid black yarn shows pale floor dust and laundry lint faster than lighter pairs, but it remains a simple staple for daily rotations.

01

Dense cotton blend and sole knit

The fabric combines 70 percent cotton with nylon and elastane for a substantial feel with structured stretch. An extra thick sole adds physical cushion between your foot and the shoe bed. Because the cotton construction is heavier than standard sheer hosiery, the knit holds more warmth in hot summer weather.

02

Firm 20-30 mmHg mechanical tension and donning

Graduated compression at 20-30 mmHg exerts firm physical pressure that is strongest at the lowest point of the leg and tapers upward. This firm rating resists stretching much more than mild 15-20 styles. You will need two hands to gather the tube, and using household rubber gloves or a sock donner makes pulling the heel past the ankle significantly easier.

03

Medium large calf boundaries and machine care

The Medium-Large size is proportioned for shoe sizes 7.5 to 11 and calf circumferences measuring 13.5 to 17 inch. A broad top welt anchors the knee high below the joint without rolling down. The socks are machine washable, though washing them inside out keeps the deep black surface free from stray fibers.

Keeping this pair alive

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.
