Compression socks : How to Choose Them and Wear Them Right

I’m going to be straight with you, because that’s how I wish someone had talked to me ten years ago.

I spent years on my feet on a production line. Same motion, same station, same concrete floor, eight hours and often more. After that, I worked 12-hour shifts in a seniors’ residence: hallways to walk, residents to help up, help down, help across the room. And when I got home, three boys were waiting, with homework, supper and hockey the next morning.

By evening, my legs weighed a ton. Swollen ankles, sock lines pressed into my skin, and one goal: sit down with my feet up on the back of the couch. I figured that was just part of the job. Nobody had ever explained, in plain words, what compression socks could do or how to pick a pair without getting it wrong.

That’s why EaseMove exists, and that’s why this guide exists. It tells you what compression socks do, who they’re for, how to choose the right level and size, and what’s different about buying them in Canada. It’s not medical advice: if you have any doubt about your own situation, read our health disclaimer and talk to your pharmacist.

In short

  • Compression socks apply gentle pressure that’s firmest at the ankle and eases up the calf, helping blood move back up.
  • The 15-20 mmHg level covers most everyday needs and is sold without a prescription in Canada.
  • Sizing is based on your ankle and calf measurements, not your shoe size.
  • Wear them during the day, take them off at night, and wash them like regular socks.

What do compression socks actually do?

The idea fits in one sentence: a compression sock squeezes more at the ankle than at the top of the calf. That graduated pressure gives blood a hand on its way back up to the heart, a trip gravity makes harder when you stay in one position for hours.

For most people who wear them, the result is legs that feel lighter and less tired at the end of the day, and ankles that swell less. Nothing magic about it. You’re just helping your legs do what they already do.

The first week I wore them at the residence, I noticed it the moment I got home: I could still stand at the kitchen counter without counting the minutes.

Socks, stockings or sleeves?

You’ll see three words used almost interchangeably, so here’s the difference.

  • Compression socks stop just below the knee. They’re by far the most common for everyday wear and what this guide is mostly about.
  • Compression stockings run above the knee or to the thigh. Pharmacists and clinics often say “compression stockings” for any length, which is why the term shows up so much in search results. For daily comfort, knee-high socks do the job for most people.
  • Compression sleeves cover the calf only, with no foot. Runners like them because they can wear their own socks underneath.

Who wears compression socks every day?

Far more people than you’d think. These are the situations where our Canadian customers, and I’m the first of them, get the most out of a pair.

You work on your feet. Factory, warehouse, hair salon, restaurant, retail, teaching: after eight hours standing, often on concrete, your legs let you know. This is the number one use for compression socks, and the one where you feel the difference on day one. On the line, I should have been wearing them from my first year. I found them far too late.

You work 12-hour shifts. PSWs, care aides, LPNs and RNs, residence and hospital staff, paramedics: twelve hours of walking, lifting and bending. Your legs don’t get a break even when you do. A good pair of compression socks is, in my opinion, the most useful thing you can buy for this job after proper shoes.

You sit all day. Sitting locks up your calves just as much as standing does. Working from home introduced a lot of people to compression socks who never thought they needed them.

You fly or drive long distances. On a Toronto–Vancouver flight or a six-hour drive with the kids in the back, compression socks keep your ankles from puffing up and make the arrival a lot more pleasant. We have a dedicated page on compression socks for flying.

You’re pregnant. I carried three boys; I know what “heavy legs in the third trimester” means. Compression socks are commonly suggested during pregnancy. Ask your care provider which level is right for you.

You’re active or recovering. Runners, hikers, hockey players: many wear compression socks or sleeves during exercise or afterward, for recovery comfort.

You just have heavy legs. No particular reason, but by evening your legs feel like lead. That’s common, and it’s exactly what 15-20 mmHg compression socks are made for.

Whether you want a discreet pair for the office or something tougher for the floor, the collection is built for those days.

Which compression level should you choose?

Pressure is measured in mmHg (millimetres of mercury). The higher the number, the tighter the sock. In Canada, you’ll mostly see three ranges.

Level How it feels Who it’s for Prescription?
8-15 mmHg Very light, like a snug sock Basic comfort, first try No
15-20 mmHg Firm but comfortable all day Standing or desk work, long shifts, travel, pregnancy, heavy legs No
20-30 mmHg Noticeably tighter On a professional’s recommendation, specific situations Usually, yes

For most people reading this guide, 15-20 mmHg is the right place to start. It’s what I wore at the residence and what I still wear. It makes a real difference on heavy legs while staying comfortable for a full twelve hours. 20-30 mmHg is something you choose on advice, not by default: tighter doesn’t mean better if the need isn’t there.

Still unsure? Our comparison 15-20 vs 20-30 mmHg: which compression level? walks through both in five minutes.

Getting the right size (the step everyone skips)

My first pair, I bought by shoe size, at the pharmacy, between two errands. It dug in behind the knee and ended up in a drawer. It’s the classic mistake, and it’s why so many people decide “compression isn’t for me.”

Size doesn’t depend on your shoe size. It depends on two measurements: your ankle circumference (at the narrowest point, just above the bone) and your calf circumference (at the widest point). Take them in the morning, before your legs swell, with a soft tape measure.

Then check the product’s size chart. Between two sizes, go by the ankle measurement: that’s where compression matters most.

Our step-by-step guide shows you exactly where to place the tape: How to measure for compression socks.

Buying compression socks in Canada: prescriptions, coverage, where to shop

This is where American and British guides leave you hanging. Here’s what applies on this side of the border.

Prescription. Compression socks up to 20 mmHg are sold freely in Canada, at pharmacies, specialty stores and online. Above that (20-30 mmHg and up), most retailers and pharmacists ask for a prescription or a professional’s recommendation, and that’s good practice.

Coverage. Provincial health plans generally don’t cover compression socks bought without a prescription. Many group and private insurance plans, on the other hand, reimburse one or two pairs a year with a prescription and a receipt. If you have benefits through work, check before you buy: the difference can be significant. We’re putting together a full page on prescription compression socks in Canada.

Pharmacy or online?

The pharmacy gives you in-person advice and someone to take your measurements, usually with a limited selection and higher prices. Buying online gives you more styles, colours and sizes, as long as you measure properly. At EaseMove, everything ships from Canada, in Canadian dollars, with no duties or surprise fees at the door, and easy returns if the size isn’t right. I know what it’s like to not have time to go back to the store.

How to put on, wear and care for your compression socks

Morning, fresh legs. Put them on when you get up, before your legs start to swell. Turn the sock inside out down to the heel, slide your foot in, then unroll it up the leg, smoothing out any wrinkles. Never roll or fold the top down: that creates a tourniquet.

All day, off at night. Wear them through your day and take them off to sleep, unless a professional tells you otherwise. If they feel uncomfortable after a few hours, that’s a sign the size or level needs a second look, not something to push through.

The first few days. Give yourself two or three days to get used to the feeling. After that, most people don’t want to go without.

Care. Machine wash on delicate, cold or warm water, no fabric softener, no bleach. Air dry. With three boys, my washer runs every day; the compression socks go in with everything else, in a mesh bag, and they hold up. A pair worn five days a week keeps its stretch for about six months: when they start sliding down or no longer feel snug, it’s time to replace them. Two pairs in rotation last longer than two pairs worn out one after the other.

When to see someone instead of buying

I’m not a health professional, and EaseMove sells comfort products, not treatments. Compression socks are for tired legs. They don’t replace a visit in these situations:

  • one leg that swells suddenly, or one leg much more than the other;
  • calf pain, redness or a warm spot;
  • numbness, persistent tingling or a sore that isn’t healing;
  • leg pain when walking that forces you to stop;
  • a known circulatory condition, diabetes or heart failure: your care provider will tell you whether compression is appropriate for you, and at what level.

In those cases, call 811 or see someone. Our page When to call 811 lists who to reach in your province.

Do your legs bother you mostly at night, with a restless, crawling feeling and an urge to move? That’s not the same as heavy legs; read our guide on restless legs syndrome. And if it’s your knee or lower back that’s worn out after a day on the floor, our guides on knee pain and lower back pain follow the same everyday-comfort approach. Standing all day and not sure which one to start with? Standing all day? What you actually need sorts it out in a minute.

Frequently asked questions

Can you wear compression socks every day?

Yes. That’s what 15-20 mmHg socks are designed for: on during the day, off at night.

What’s the difference between compression socks and compression stockings?

Length. Socks stop below the knee; stockings go above the knee or to the thigh. For everyday comfort, knee-high socks are what most people need.

Do you need a prescription for compression socks in Canada?

Not for levels up to 20 mmHg. A prescription is usually required from 20-30 mmHg up, and it helps with insurance reimbursement.

My socks slide down or bunch behind the knee. Is that normal?

No. A sock that slides is too big; one that bunches or digs in behind the knee is too long or too small. Re-measure with our sizing guide.

Do compression socks slim your legs or make varicose veins go away?

No. They reduce the heavy feeling and end-of-day swelling. For varicose veins or any question about how your veins look, talk to a professional.

How long does a pair last?

About six months of regular wear, a bit longer if you rotate two pairs.
