This two-pair pack combines a brown base with a crisp polka dot pattern across a durable natural-fiber knit. Spun with 70 percent cotton, 22 percent nylon, and 8 percent elastane, the fabric sits soft against the skin while maintaining structured tension. The 20-30 mmHg mechanical gradient delivers firm pressure that is tightest at the ankle and tapers toward the upper calf band. A thickened sole adds dense padding under the heel and forefoot for long hours on your feet.

The rich brown yarn is patterned with contrasting polka dots, offering a warm earth-tone look that pairs well with clogs or work boots. The knit is 70 percent cotton, blended with nylon and elastane for stretch retention. A thickened footbed adds soft material underfoot to buffer impact against hard floors, though this extra yarn density makes the foot area warmer on hot summer days.
This Small-Medium size fits shoe sizes from 4.5 to 7.5 and calf circumferences between 10.5 and 13.5 inches. To ensure the correct gradient, measure your calf around the widest point before choosing your pair. If your calf measures over 13.5 inches, this size will pull excessively tight across the upper band and leave indentations on the skin.
The 20-30 mmHg rating provides a firm compression profile that supports the lower leg mechanically from the ankle upward. Because this gauge is substantially tighter and stiffer than mild 15-20 mmHg socks, pulling it up over the heel requires two hands. Using household rubber gloves or a metal sock donner provides the grip needed to gather the cotton fabric and position the heel cup smoothly.

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.
