Frequently Asked Questions

What makes Therafirm Ease Bold 20-30 mmHg Knee High Compression Socks different?

Therafirm Ease Bold 20-30 mmHg Knee High Compression Socks provide firm 20-30 mmHg graduated compression that is greatest at the ankle and decreases up the leg. Comfort designed top is non-restrictive while staying in place all day. Ultra stretchy yarns make the sock easier to put on.

What does 20-30 mmHg mean, and what does it help with?

20-30 mmHg is firm graduated compression: pressure is greatest at the ankle and decreases up the leg. In these knee high socks, it is often recommended by doctors for varicose veins and moderate swelling, and may help relieve tired, aching legs. Talk to your doctor about whether 20-30 mmHg is right for you.

How do I know I’m ordering the right size?

Measure your ankle and widest calf area and check the garment length if the size chart requires it. Compare the results with the size chart for this exact product before choosing a variant. If you fall between sizes, use the brand’s fitting guidance rather than guessing.

How do I put these on and take them off?

Put the garment on when your legs are dry. Turn it inside out to the heel, guide your foot into place, and work the fabric gradually up the leg without pulling on the top band. Smooth out wrinkles; do not fold or roll the upper edge. To remove it, ease the fabric downward in stages. If gripping or applying the garment is difficult, consider donning and doffing aids, including application gloves and stocking donners.

How should I wash and care for this garment?

Therafirm’s general compression-garment care guide recommends hand washing in cool or lukewarm water with a mild detergent. Do not wring, bleach or iron the garment; lay flat, line dry or drip dry away from excessive heat. Check your garment label for any style-specific care directions.
