Measure the circumference of your calf at its widest point and choose from that number — not from your shoe size. Shoe size does not predict calf circumference, which is why so many compression socks stop halfway up the leg or cut a groove into the calf by lunchtime.

Black, and nude which stays discreet under clothing. Both come in all three sizes.

Not if the size is right. Sliding down is what happens when a sock is too big in the calf — which is exactly why we size by calf circumference rather than shoe size. Measure once and they stay where you put them.

Message us before you send anything back. Nine times out of ten a pair that “did not work” was simply the wrong calf size, and we would rather swap it than refund it.

The difference is how you get them on. An ordinary stocking is a closed tube, so the only route onto your leg is to stretch it wider than your calf and drag it up. Nordvia socks open with a full-length side zipper — unzipped they lie completely flat. You lay your foot and calf down, draw the zip up, and it closes around your leg. About thirty seconds, seated, unaided.

The graduated medical compression is identical. Only getting them on changes.

Yes. True 15 to 20 mmHg graduated medical compression — firmest at the ankle, easing progressively towards the calf. The zip runs up the outside of the leg, which is not where the graduated pressure is generated, so it does not compromise the clinical effect in any way.

15 to 20 mmHg is the standard everyday range for reducing swelling, easing heavy legs and prevention. Higher grades (20–30 mmHg and above) are generally prescribed for diagnosed venous conditions. If a doctor has given you a specific grade, follow that rather than switching.

• Older adults who cannot safely bend to their feet
• Post-operative and recovering patients
• People with varicose veins, venous insufficiency or oedema
• Anyone with arthritis or limited grip strength
• People with wide calves that ordinary stockings never reach
• Frequent travellers
• Anyone standing or seated still for long hours

A soft fabric guard sits behind the zip teeth, so nothing metal touches skin at any point. That lining is the reason the zip can run the full length of the sock rather than being a short ankle opening.

Because compression only helps on the days you actually wear it, and one pair means a laundry day is a day without. It is also the cheaper route per pair, and rotating between pairs makes each one last considerably longer.

Most people notice less heaviness at the end of the first full day of wear. Swelling and sock marks usually take a few days of consistent daily wear. We suggest wearing them every day for at least two weeks before you judge.

All day, yes — 15 to 20 mmHg is designed for it. Most people put them on in the morning and take them off at bedtime. They are not intended to be slept in.

Hand wash cold, or machine wash at 30C on a delicate cycle. Close the zipper before washing to protect the fabric. Air dry only — the tumble dryer and the iron both damage the elastane and reduce the compression.

With daily wear, any compression sock is generally past its useful pressure at around three to six months — the elastane relaxes with every wear and wash. The practical tell is that they become easier to put on than when they were new. Rotating between several pairs extends the life of each, which is the real reason the bundles exist.
