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 includes 2 pairs of knee highs knit in solid black cotton. The yarn blend uses 70 percent cotton, 22 percent nylon, and 8 percent spandex for a matte surface that works under work trousers or dark uniforms. True 15-20 mmHg graduated compression sits firmest at the lower ankle and tapers toward the top welt. The dark black fabric will collect pale lint from the laundry, so wash them inside out.

Each size is a separate listing with its own price. The middle column is the calf circumference the maker prints for that size.

Size XX-Large accommodates shoe sizes from US 5 to 9 and calf circumferences from 16 inch to 22 inch. The dedicated wide calf cylinder expands across the leg without overstretching the stitches. A broad top welt anchors the upper edge below the knee joint.
The 70 percent cotton content lets air move through the leg of the sock during long shifts. Terry loop padding runs along the footbed to soften hard floor impact. This extra thickness underfoot means you will need adequate vertical depth in your everyday shoes.
A continuous 15-20 mmHg gradient applies firm tension at the base and eases upward along five distinct zones. The nylon and spandex core provides steady elasticity that requires gathering the sock down to the heel pocket before pulling it over the foot.

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.
