I’ve been a nurse for over thirty years, and my honest relationship with compression socks is this: I wear them, not as often as I should, and I wish I’d started decades earlier.
My legs are now covered in spider veins and varicose veins. Some of that comes with standing on hard floors for thirty years. Some of it probably didn’t have to.
If you’re a nurse deciding whether these are worth it, here’s what I’ve learned from wearing them on and off for years.
This isn’t medical advice — if you have circulation issues, clotting risk, or diabetes, talk to your doctor before choosing a compression level. What follows is what’s worked for my legs on the floor.
What they actually do for me
Swelling is the main one. My ankles swell badly when I’m on my feet all shift. Compression socks make a noticeable difference.
They also help the pain in my feet. I didn’t expect that, and I can’t tell you the mechanism, but it’s consistent enough that I’ve stopped questioning it.
That’s it. They don’t make a twelve-hour shift pleasant. They make your legs feel less wrecked at the end of it.
Compression level: the number that matters
Compression socks are rated in mmHg, and the number tells you how tight they are. This is the spec to get right.
I wear 20-30 mmHg. That’s my recommendation for nurses. It’s firm enough to actually do something about swelling and not so tight it becomes a problem.
15-20 mmHg is the level most often marketed to nurses. It’s fine, and it’s a reasonable place to start if you’ve never worn them — but for a twelve-hour shift with real swelling, I find it doesn’t do enough.
Above 30 mmHg is where I’d stop without a doctor telling you otherwise. I’ve tried up to 60. They felt too tight on me and they made me itch, which is its own kind of misery at hour eight. Higher compression is generally prescription territory for a reason.
Anything unrated is just a sock. This is the big mistake — cheap “compression” socks with no mmHg number on the package are compression-shaped, not compression. If there’s no number, you’re buying knee socks.
Get the full foot
I can’t wear open-toe compression socks or the ones that only cover part of the foot. Full foot, every time.
But here’s the thing nobody tells you: even with a full foot, you have to pull the toe out.
Compression socks pull tight across the front of your foot, and if the toe section is stretched taut against your toes, it hurts within an hour. Before I put my shoes on, I pull the fabric away from the end of my toes to give them room. Small adjustment, big difference.
If your compression socks make your toes ache, that’s probably why — not the wrong size.
Knee-high, not thigh-high
Thigh-highs are sold for this and I’ve tried them. They roll down on me and get uncomfortable, and a compression sock that’s rolled down at the knee is worse than no sock at all — you’ve got a tight band in one spot instead of graduated compression.
Knee-high is the practical choice for nursing. Easier to get on, stays put, works with scrubs.
The double-sock trick
This is the tip I’d pass on to any new nurse.
Put a regular sock on over your compression sock.
A lot of compression socks are made from thin, slippery fabric with essentially no cushioning. Inside a shoe for twelve hours, that’s not enough between your foot and the insole. A normal sock over top gives you padding and stops the slipping.
It sounds like too much sock. It isn’t. This is the difference between wearing them all shift and taking them off at lunch.
Make sure your shoes have room for it — one more argument for not buying shoes tight.
Things that will annoy you
Rolling down. Some pairs do it, some don’t, and it’s hard to predict from the packaging. If a pair rolls, replace it — you won’t fix it.
Itching. Mine itch when they’re too tight. If a pair makes you itch, the compression level is probably too high for you.
Heat. They’re an extra layer. In a warm unit in summer, you’ll notice.
Getting them on has never been a problem for me, though plenty of people find it is — if that’s you, look for a wider top band or a donning aid.
What to buy
I’ll be honest about a limitation here: I’ve worn a lot of these over the years and I couldn’t tell you a single brand I’ve stuck with. That’s partly because compression socks are fairly interchangeable — the spec matters far more than the label.
So buy by spec, not by brand:
- 20-30 mmHg, clearly printed on the package
- Full foot, closed toe
- Knee-high
- Actual fabric with some substance, not the thinnest option
- Several pairs — you’ll wash them constantly
If the listing doesn’t state an mmHg range, skip it.
The part I’d tell my younger self
Wear them. Not “on the bad days,” not “when my ankles are already swollen.” Wear them.
The most common mistake nurses make with compression socks isn’t buying the wrong compression level or the wrong length. It’s not wearing them at all, which is exactly what I did for years.
I can’t prove that starting earlier would have prevented my veins. But I know that thirty years of twelve-hour shifts on hard floors did something, and I know I spent most of those years with a drawer full of compression socks I wasn’t putting on.
Buy a few pairs. Wear them on ordinary shifts, not just bad ones.
