The best compression socks for nurses

You know the feeling. Hour ten, your legs feel like they are full of wet sand, and when you finally peel your socks off at home there is a deep red ring around each ankle. Standing and walking all day lets fluid pool in the lower legs, and gravity does not take breaks just because you cannot.

Compression socks are one of the cheapest, simplest things you can try about it. Below are the pairs worth buying for long shifts, then a plain explanation of pressure levels, sizing, washing, and who should talk to a doctor before wearing them.

Do compression socks actually help on long shifts?

The research on people who stand for work is small but fairly consistent. A study of security guards working 12-hour standing shifts found that those in regular socks ended the shift with more lower-leg swelling, muscle fatigue and discomfort, while those wearing compression stockings showed no significant change. A separate trial of workers who stood for eight hours found that compression stockings prevented the leg swelling that showed up without them.

Two honest caveats. First, the same eight-hour study found the stockings did not stop leg pain from building during the workday, so think of them as helping with swelling and heaviness rather than as a cure for sore legs. Second, these are small studies, and none of them was done on nurses specifically. Still, for something you can try for the price of lunch, the odds are in your favor.

What the pressure numbers mean

Compression is measured in millimeters of mercury (mmHg), the same unit as blood pressure. Graduated compression socks squeeze hardest at the ankle and less as they go up the calf, which helps push fluid back up the leg instead of letting it pool.

• 8 to 15 mmHg (light): gentle. A good introduction if you have never worn compression.
• 15 to 20 mmHg (moderate): the sweet spot for most people on long shifts. Sold without a prescription.
• 20 to 30 mmHg (firm): a noticeable squeeze. Some people with heavier swelling prefer it.
• 30 mmHg and up: medical-grade territory. This is something a doctor prescribes and fits, not something to pick off a shelf.

In the security guard study, neither 15 to 20 nor 20 to 30 mmHg came out clearly ahead, and the authors suggested the lighter level may be enough. The 15 to 20 mmHg socks were also easier to get on, which matters at 5:45 a.m. Start there.

Check with your doctor first before wearing anything firmer than 20 mmHg, or any compression at all if you have diabetes, neuropathy (nerve damage), peripheral artery disease or any problem with your circulation. The NHS notes that compression stockings are not suitable for people with blood flow problems in their arteries, and a squeeze that helps healthy veins can harm legs that already struggle to get enough blood.

The best first pair

If you are buying one pair to see what the fuss is about, buy a nice one. A pair that feels like a good sock rather than a medical device is a pair you will actually keep wearing. The Sockwell Circulator uses a merino blend that handles sweat well and comes in patterns that do not look like hospital issue.

The budget multipack

Once you know compression works for you, you need enough pairs for a full week, plus spares for when laundry day slips. A multipack covers that without the sticker shock. They are thinner and wear out sooner than premium pairs, but the price per pair makes up for it.

When you need a firmer squeeze

If 15 to 20 mmHg is not doing enough and your legs still swell by hour eight, a firmer sock may help. Please read the doctor note above first: 20 to 30 mmHg is firm, and it is not for everyone.

Worth the splurge

SIGVARIS has made compression hosiery for a long time, and it shows in the details: proper sizing by ankle and calf measurement, and merino wool that stays comfortable all shift. You pay more per pair, so this is the one for people who would rather own four excellent pairs than twelve okay ones, or whose calves do not fit standard packs.

Cotton and gentle

Some people simply hate the slippery, sporty feel of nylon compression. A cotton-rich pair with a lighter squeeze is a gentler way in. It may not be enough for heavily swollen legs, but it is a comfortable everyday option.

How to get the size right

Compression only works if the sock fits. Too loose and it does nothing. Too tight and it digs in at the top, which is exactly where you do not want pressure.

1. Measure your calf at its widest point, and your ankle just above the bone if the brand asks for it. Many brands size by calf, not just shoe size.
2. Measure in the morning, before your legs swell.
3. Check the top band. It should sit below the knee crease without rolling down or leaving a deep groove.
4. If you have wide calves, look for brands that size by measurement or sell wide calf versions, rather than squeezing into a one-size-fits-most pack.

Putting them on without a workout

The easiest way, according to MedlinePlus, is first thing in the morning, when your legs are least swollen. Then try this:

• Turn the sock inside out down to the heel.
• Slide your foot in and get the heel in place.
• Roll (do not yank) the rest up your leg, smoothing out wrinkles as you go.

Wrinkles and bunched fabric create pressure lines, so take the extra ten seconds. Dry hands help. So does not putting them on straight after a hot shower.

How to wash compression socks (and when to replace them)

Heat is the enemy of elastic. MedlinePlus suggests washing compression stockings daily with mild soap, rinsing and letting them air dry, and owning at least two pairs so one can dry while you wear the other. Most makers say machine washing on cold or gentle is fine, but check the label, and skip the dryer and the fabric softener.

Even with good care, compression fades. MedlinePlus says to replace them every three to six months to keep the right level of support. If a pair slides down your leg or feels like a normal sock, it is time.

What to skip

• “Compression” socks with no mmHg number. If the pressure is not listed, you have no idea what you are getting.
• Firm or medical-grade pressure without advice. More is not better if your legs do not need it.
• Wearing them to bed unless a doctor has told you to. Compression for standing work is a daytime thing.
• Ignoring warning signs. Numbness, tingling, pain, skin color changes or marks that do not fade are a reason to take them off and get checked.

Knee high or thigh high?

For long shifts, knee high is what most people wear, and it is what all the picks above are. Swelling from standing mostly gathers around the ankles and lower legs, and knee socks are far easier to put on, wash and live with. Thigh-high stockings and tights exist, but they are usually something a doctor recommends for a specific reason.

Can I wear them on night shift?

Yes. Your legs do not know what time it is, and a 12-hour night involves just as much standing as a day. Put them on before you leave for work, take them off when you get home, and let your legs rest before you sleep.

Do they replace good shoes?

No. Compression helps your legs; shoes protect your feet. Long standing affects the whole body, as Canada’s workplace safety centre CCOHS points out, so it is worth fixing both. Our guide to the best shoes for nurses covers that half. For everything else, start with the nurse essentials list, and for after-shift leg care, the recovery guide. Compression socks in fun patterns also make a surprisingly well-received gift.

Follow your own unit’s dress code and infection control rules, which always come first.
