Sigvaris 230 Essential Cotton 20-30 mmHg Knee High Closed Toe for Women

Fabric and construction

The line is built around a classic ribbed knit built from Supima cotton. It comes as a knee high with a closed toe, in the sizes shown on this page.

What this compression class is for

Sigvaris and JOBST both call 20-30 mmHg the class doctors prescribe most often, typically for more noticeable varicose veins, mild-to-moderate edema, or recovery after some vein procedures. Sigvaris's own guidance is to talk to your doctor about which class fits a diagnosed condition before you buy; nothing here should be read as medical advice.

Pressure is built to be highest at the ankle and to ease gradually up the leg, the standard mechanism behind every mmHg class.

Compression socks are sized to your leg, not your shoe size. The fitting method JOBST's own compression institute publishes measures the narrowest point of the ankle, the widest point of the calf, and sometimes leg length, taken while seated with legs free of swelling. Check this line's own size chart rather than guessing from S/M/L, since two brands rarely match.

JOBST's donning instructions: turn the sock inside-out down to the heel, ease it over the foot, then gradually turn it right-side-out while working it up the leg and smoothing out any wrinkles. Rubber gloves add grip on firmer classes, and a separate donning aid (sold on our Donning Aid page) helps if bending down to your foot is hard.

Sigvaris recommends hand-washing, or a gentle machine cycle with the sock turned inside-out, in lukewarm water with a mild detergent - no bleach or fabric softener, then air-dry. JOBST advises washing after each wear or every other day, and replacing compression hosiery about every six months of normal use, sooner if the fabric loosens.

Cleveland Clinic points out that compression works with gravity and movement, so most people take these off at bedtime; wearing them overnight is really a clinician-directed step for specific situations like a healing leg wound, not a default.
