TrueFit compression socks FAQ

S/M fits women's US 5–9.5 and men's US 4–8.5 with a calf up to 16 inches (41 cm). L/XL fits women's US 10–13 and men's US 9–13 with a calf up to 20 inches (51 cm). If your shoe size and your calf point at different sizes, follow the calf.

Measure in the morning, before any swelling builds. Stand up, find the widest point of your calf — usually about 5 inches below the back of the knee — and wrap a soft tape around it snugly without compressing the skin. Write down the number in inches or centimetres and check it against the size guide.

Size up. A slightly roomier L/XL still delivers graduated compression and stays comfortable for twelve hours; an S/M that is genuinely too small will feel like a band around your leg by lunchtime and you will stop wearing it.

Yes. The knee-high matte black design is deliberately plain so it reads as an ordinary dress or sport sock on anyone, and every size is listed in both women's and men's shoe sizes.

L/XL fits calves up to 20 inches and the wide comfort strap spreads its grip rather than biting into muscle. Above 20 inches the fit gets tight and we would rather you didn't order — email us and we'll tell you honestly.

Usually yes, but put them on first thing in the morning when swelling is at its lowest. Pulling compression over an already swollen ankle in the evening is difficult and less effective.

Email us and we'll exchange it free of charge inside 30 days, or refund you — including pairs you have already worn. See the returns page for the exact steps.

Knee-high. The comfort strap should sit roughly two finger-widths below the back of the knee so it never rubs the crease when you bend.

Roughly 20–30 mmHg at the ankle, easing to 12–16 mmHg at the calf and 8–10 mmHg at the top. That graduated profile is what encourages blood back up the leg instead of pooling around your ankles, and it does not require a prescription.

No. It is the standard everyday range for tired, achy or mildly swollen legs and it is what most nurses, flight crew and hospitality staff wear all day. Drugstore socks are usually 8–15 or 15–20 mmHg, which is why people who step up to TrueFit notice a difference.

TrueFit is a graduated wellness garment sold without a prescription. It is not a medical device and is not intended to diagnose, treat, cure or prevent any condition. If you have a diagnosed venous or arterial condition, your clinician should tell you what to wear.

No. A conventional sock finishes in a narrow elastic that behaves like a tourniquet. TrueFit finishes in a wide comfort strap that spreads pressure over a broader band of the calf, so it holds the sock up without denting your leg.

Most people notice less heaviness and aching on the first full day, because fluid never gets a chance to accumulate. Reduced end-of-day ankle swelling usually shows up within the first week of consistent daily wear.

Because they are doing something. Stepping from a 15–20 mmHg drugstore sock to true 20–30 mmHg feels firm at first. Wear them four to six hours on days one and two, then go to a full day — nearly everyone stops noticing them by day three.

A sleeve stops at the ankle and leaves the foot uncovered, so the part of the leg where fluid pools most gets no support. Sleeves suit runners who want calf support inside their own socks; for swelling and all-day standing, full socks are the better tool.

Put them on in the morning and take them off at bedtime. If you have never worn compression, start with four to six hours for the first two days and build up from there.

Not routinely. Lying flat removes the gravity problem compression is solving, and overnight wear can irritate skin. Sleep in compression only if a clinician has specifically told you to.

Yes — that is exactly what most of our customers do. Nurses, teachers, chefs, warehouse staff and cabin crew wear them for full shifts. A fresh pair each day is why the multi-pair packs exist.

Yes, and it is one of the most common reasons people buy. Put them on before you leave for the airport, not once you're seated, and keep them on until you reach your accommodation.

Yes. Many runners wear them for recovery after long runs as well as during easy miles. They are knit for all-day comfort rather than race-day weight, so they are best used for training and recovery.

Graduated compression is commonly recommended in pregnancy for swelling and heaviness, and plenty of our customers use them through the third trimester. Confirm with your midwife or doctor first, especially if you have any pregnancy complication.

Mild graduated compression is widely used by both groups, but circulation varies. If you have diabetes with neuropathy, peripheral arterial disease, heart failure, an open wound or advanced venous disease, get your clinician's approval before wearing any compression garment.

Anyone with untreated peripheral arterial disease, an active DVT, decompensated heart failure, severe neuropathy, an open ulcer or a skin infection on the leg. If you're unsure, ask a clinician before ordering.

A thin liner underneath is fine if your skin is sensitive. Don't layer another compression garment on top — you can't stack pressures safely.

Black only. It is the right call for people wearing them under scrubs, uniforms and work trousers, and it is the most requested change in our inbox.

Machine wash cold on a gentle cycle, inside a mesh bag if you have one, and hang to dry. Skip fabric softener and the tumble dryer — heat is what destroys compression fibres.

Roughly four to six months of regular wear per pair when washed cold and air-dried. Hot washes and tumble drying can halve that.

Two reasons. Compression only helps on the days you actually wear it, so you need a clean pair ready each morning. And rotating pairs gives the elastane a recovery day, which measurably extends the life of the whole set.

No to both. Bleach breaks the fibres and any direct heat kills the stretch.

Wear them for 30 days. If your legs don't feel better, email us and we refund the order. You keep the pairs you have already worn and you do not have to justify the decision.

No. We don't want used socks back, and requiring unworn condition would make a 30-day trial meaningless.
