Most compression socks won't tell you the number. The real ones print it on the box.
Built to a number · 20–30 mmHg
"Compression" on its own is a marketing word. The number is the spec. Ovena socks are 20–30 mmHg medical-grade graduated compression — firmest at the ankle, easing up the calf — and the number is printed right on the box, so you know exactly what your legs are getting.
Every pair ships with a free pH-balanced cleanser — a $3.99 value

"Most socks just say 'compression.' The real ones come down to the number — 20 to 30 mmHg is the level I recommend for firm, all-day support on long shifts, travel days, and standing work — and it's printed on every Ovena box. Check the number before you buy."
Physician-led brand · The number is the spec.
What the number does
Fluid pooling, or supported upward flow.
Gravity pulls fluid down; by the end of a long day it can pool around the ankles. Graduated compression is snug at the ankle and eases up the calf, supporting flow back up the leg — which helps improve circulation, reduce swelling, and relieve tired, achy legs. Worn as directed.

Read the box, not the adjectives
Three things the number tells you.
One line of print does more work than a page of adjectives.
The level
20–30 mmHg is a firm, daily-wear support level — a real spec, not a softness rating.
The direction
Graduated means the pressure has a gradient — firmest at the ankle, easing up the calf.
The accountability
A brand that prints the number is making a claim you can hold it to. Vague listings can't be checked.
The number that matters
On the box. In the sock.

From box to wash
What the number feels like, day one.
A 20–30 mmHg sock is a firmer sock — here's the honest rhythm of it.
1
Check the box
20–30 mmHg, printed where you can see it — the spec you chose on purpose.
2
Feel it at the ankle
A firm sock, snug where it should be. You'll feel it the first time — that's the level working, not a sizing mistake.
3
Forget it by mid-morning
Graduated support settles in for the shift, the flight, or the long day on your feet.
4
Wash it right
The included pH-balanced cleanser is gentle on elastic fibers. Cool wash, no bleach or fabric softener, air dry.
Good to know
Questions, answered.
What does 20–30 mmHg actually mean?
It's the pressure the sock applies, measured in millimeters of mercury — the same unit a blood-pressure cuff uses. Ovena socks apply 20–30 mmHg at the ankle, graduated so the pressure eases as it moves up the calf.
Why does graduated matter?
Uniform squeeze is just a tight sock. A graduated sock is firmest at the ankle and eases upward, supporting flow back up the leg — which helps improve circulation, reduce swelling, and relieve tired, achy legs when worn as directed.
Why does it matter that the number is on the box?
A printed spec is a claim the brand can be held to. If a listing only says "compression" with no number, you can't know what level you're buying — or whether it's graduated at all.
Is a higher number always better?
No — more pressure is not automatically better. 20–30 mmHg is a firm daily-wear level. Compression isn't appropriate for everyone — significant peripheral arterial disease or severe neuropathy calls for clinician guidance first, and if you have any doubt, ask your clinician. If you notice numbness, tingling, skin colour change, or pain while wearing them, take them off and check with a clinician.
They feel tight the first time — is that normal?
Yes. A real 20–30 mmHg sock feels snug at the ankle the moment it's on — that's the level, not a sizing mistake. It should feel supportive, not painful; if bending or reaching makes donning hard, our long-handle sock aid — designed to make compression-sock donning easier — helps.
How do I pick my size?
Two measurements: your ankle at the narrowest point and your calf at the widest. S fits ankles 7–8.5 in and calves 11–14 in · M 8.5–10 in and 13–16 in · L 10–11.5 in and 15–18 in · XL 11.5–13 in and 17–20 in. Between sizes, or ankle and calf pointing to different sizes? Go by your calf. The full chart is in the gallery above — still unsure, email info@ovenahealth.com. Like all compression hosiery, they're a wear item — daily wearers usually keep a rotation and refresh pairs a few times a year.
What if the size is wrong?
Unworn, unused pairs in original packaging can be returned within 30 days — see our refund policy. Email info@ovenahealth.com to start a return, then reorder your size.
Are they FSA/HSA eligible?
Many FSA/HSA plans cover 20–30 mmHg compression socks — verify with your plan.
