Two pairs of extra thick black knee highs in a 70 percent cotton blend with firm 20-30 mmHg graduated tension.
4.2 (1,055)calf 10.5-17"

This pack contains 2 pairs of knee high socks combining a soft grey base with pink accents. The heavy gauge knit uses a blend of 70% cotton, 22% nylon, and 8% elastane for a natural surface against the skin. Graduated tension runs at 20-30 mmHg, applying the strongest mechanical hold at the ankle and easing toward the calf band. The dense cotton construction makes this pair noticeably warmer than synthetic alternatives, which works well in cold rooms but feels heavy in peak summer heat.

Graduated compression at 20-30 mmHg delivers a firm hold through the lower leg. Because this level is significantly tighter than 15-20 mmHg, gathering the dense cotton fabric requires steady effort. Using rubber gloves or a sock donner makes pulling the heel pocket over the foot much easier.
The yarn blend features 70% cotton with nylon and elastane for stretch. An extra thick footbed adds dense underfoot cushioning inside work shoes or boots. Wash these pairs directly in the machine with regular laundry to maintain clean fibers across repeated wear.
The Medium-Large size accommodates shoe sizes from 7.5 to 11 and calf circumferences between 13.5 and 17 inch. The top band is designed wide to distribute tension evenly just below the knee. Measuring your calf at the widest point ensures the cuff stays secure without digging.

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.
