This is general information, not medical advice. Talk to your midwife, OB or GP about your own symptoms. Severe or sudden pain, bleeding, a fever, or regular contractions before 37 weeks need a call to your provider now — before you buy anything.
The short answer
Start at 15-20 mmHg, knee high, in a wide-calf cut, and put them on before you get out of bed. Compression works by supporting the veins against gravity, so it does most when you apply it before the swelling has arrived. Wide calf matters because pregnancy swells your calves too, and a sock sized for your foot often will not go over them.
Why your legs and feet swell
Two things, both normal. Your blood volume increases substantially in pregnancy, and the growing uterus presses on the large veins returning blood from your legs. The result is that fluid pools in the lowest part of you, which is why it is worse at the end of the day, worse in heat, and worse after standing.
The NHS describes swollen ankles, feet and fingers as common in pregnancy and lists the practical measures: avoiding standing for long periods, putting your feet up, comfortable shoes, and compression. MedlinePlus covers the related territory of varicose veins, which pregnancy also makes more likely for the same mechanical reasons.
Compression socks help by applying graduated pressure — firmest at the ankle, lighter as they go up — which supports the vein walls and helps blood move upward instead of pooling.
How much compression? The mmHg question
| Band | What it is for | Note |
|---|---|---|
| 8-15 mmHg | Mild heaviness; a first try | Does little for real swelling |
| 15-20 mmHg | Most pregnancy swelling; flying; long days | Where to start |
| 20-30 mmHg | Heavier swelling; varicose veins; long shifts standing | Worth checking with your provider |
| 30-40 mmHg | Prescribed use | Not something to self-select |
Most people should start at 15-20 and move up only if it is not enough. Firmer is not automatically better: harder-to-wear socks get left in the drawer, and the compression you actually wear beats the compression you bought.
The practical problems, and how to solve them
They will not go over my calf
The most common complaint, and it is a sizing issue rather than a strength issue. Compression socks are sized by ankle and calf circumference, not shoe size, and pregnancy swells your calf. Measure your calf at its widest, in the morning, and buy a wide-calf cut if you are near a boundary.
I cannot get them on at all
- Put them on before you get out of bed, when swelling is lowest. This is the single most useful tip and it also makes them work better.
- Turn the sock inside out to the heel, get the foot in, then roll the leg up rather than pulling.
- Rubber washing-up gloves give you grip and make a surprising difference.
- A sock aid or donning aid exists for exactly this and is cheap. Late in pregnancy, bending to your own feet is the actual obstacle.
They are unbearable in summer
Cotton-rich socks are noticeably cooler than synthetic. Open-toe versions help. Putting them on in the morning and taking them off in the evening rather than wearing them overnight helps most.
How we picked
Six axes: compression actually delivered, calf width, ease of getting on, breathability, durability, and cost per pair. Calf width and ease of getting on are weighted heavily because they are the two things that decide whether socks get worn at all, and unworn socks have no compression value whatsoever.
We read the current listings and the reported experience rather than wearing these. The method is on how we pick.
When swelling is not just swelling
This is the part that matters most on this page.
Contact your provider urgently if you have:
- Sudden or severe swelling, especially of your face or hands
- Swelling with a headache, visual changes, or pain under your ribs — that combination can indicate preeclampsia
- Swelling in one leg only, especially with pain, warmth or redness in the calf — this needs urgent assessment for a clot
- Chest pain or breathlessness
One-sided calf swelling or pain is the one to take most seriously and the one people most often rationalize. Do not put compression socks on a painful, swollen single calf and wait to see; get it looked at.
Our swollen feet guide covers the non-sock measures, and the compression socks guide goes into when and how long to wear them.
Every pick, in detail
Scores below are ours. They come from the published specification sheets and from the patterns in what buyers consistently report — not from wearing these ourselves.
Top pick · Starting out, and most pregnancies
8.8/10Momcozy Pregnancy Compression Socks 15-20mmHg Wide Calf
The sensible default. 15-20 mmHg is the band most people should start in, and a wide-calf cut addresses the specific pregnancy problem: your calves swell too, so a sock sized for your foot often will not go over them. Both decisions are right for this use.
- Compression
- 15-20 mmHg
- Calf
- Wide-calf cut
- Height
- Knee high
- Toe
- Closed
What works
- 15-20 mmHg — the right starting band for most people
- Wide-calf cut, which standard socks often are not
- Knee high, which is the length that matters for pregnancy swelling
- Easier to get on than a 20-30 mmHg sock
What it gives up
- Not enough compression for heavier swelling
- Fewer pairs per pack than the budget options
- Synthetic fabric, warm in summer
- Loses elasticity over a few months of daily wear
Skip it ifyour swelling is significant and your provider has suggested firmer compression.

Pick 2 · Long days standing, and warm weather
8.6/10LEVSOX Cotton Compression Socks 20-30mmHg Knee High
Firmer compression in cotton-rich fabric, which is the combination that matters if you are on your feet for a shift. Cotton makes a real difference to how tolerable a 20-30 mmHg sock is in summer, and 20-30 is the band for heavier swelling — worth checking with your provider first.
- Compression
- 20-30 mmHg
- Fabric
- Cotton-rich
- Height
- Knee high
- Use
- Nursing shifts, travel, pregnancy
What works
- 20-30 mmHg for heavier swelling
- Cotton-rich, noticeably cooler than synthetic
- Knee high
- Holds compression better than the budget multi-packs
What it gives up
- Harder to get on than 15-20 mmHg
- Firmer compression is worth discussing with your provider
- Cotton loses shape slightly through a day
- More expensive per pair
Skip it ifyou have not tried 15-20 mmHg yet — start lighter.
| Compression delivered | 9.0 |

Pick 3 · When standard socks will not go on
8.4/10LEVSOX Wide Calf Compression Socks Plus Size 15-20mmHg
The answer to the most common practical failure in this category: the sock fits your foot and will not pass your calf. Sized through the leg rather than just the foot, at the lighter compression band that is easier to get on in the first place.
- Compression
- 15-20 mmHg
- Calf
- Wide calf, plus size
- Height
- Knee high
- Fit
- Sized up through the leg, not just the foot
What works
- Sized through the leg, not just the foot
- 15-20 mmHg is easier to pull on than firmer bands
- Plus-size range
- Knee high
What it gives up
- Lighter compression than some swelling needs
- Wide-calf cuts can slide down on narrower legs
- Synthetic fabric, warm
- Fewer colors
Skip it ifstandard-width socks already fit your calf comfortably.
| Compression delivered | 8.2 |
|---|---|
| Calf width | 9.5 |
| Ease of getting on | 8.8 |
| Breathability | 7.4 |
| Durability | 7.8 |
| Cost per pair | 8.0 |

Pick 4 · Having a clean pair every day
8.1/10CHARMKING Compression Socks 15-20 mmHg 8 Pairs
Eight pairs at 15-20 mmHg, which matters because compression socks need washing daily and you will not keep wearing them if there is never a clean pair. Judge them as consumables: the elasticity goes sooner than the single-pair options, and at this price that is a reasonable trade.
- Compression
- 15-20 mmHg
- Pack
- 8 pairs
- Height
- Knee high
- Use
- Everyday, athletic, travel
What works
- Eight pairs — a clean pair every day without daily washing
- 15-20 mmHg, the right starting band
- Lowest cost per pair here
- Wide enough range of colors to wear to work
What it gives up
- Elasticity degrades sooner than single-pair socks
- Compression consistency varies between pairs
- Standard calf width
- Synthetic, warm
Skip it ifyou want socks that still compress properly in three months.
| Compression delivered | 7.6 |
|---|---|
| Calf width | 7.4 |
| Ease of getting on | 8.4 |
| Breathability | 7.0 |
| Durability | 6.8 |
| Cost per pair | 9.4 |

Pick 5 · A first try, or if compression feels like too much
7.8/10Doc Miller Open Toe Compression Socks 8-15 mmHg
The lightest band here and an open toe, which together make it the gentlest introduction. Worth knowing about because plenty of people find full compression unpleasant at first, and 8-15 mmHg with the toes free is a tolerable way to start rather than giving up entirely.
- Compression
- 8-15 mmHg — the lightest here
- Toe
- Open
- Height
- Knee high
- Use
- A first try if full compression feels like too much
What works
- Lightest compression — the easiest to tolerate
- Open toe, which suits sensitive or swollen toes
- Easiest of these to get on
- A sensible first try before committing to firmer socks
What it gives up
- 8-15 mmHg does little for significant swelling
- Open toe can roll at the edge
- Not what most swelling actually needs
- You may need to buy again at a firmer band
Skip it ifyour legs are genuinely swollen — this band is too light to do much.
| Compression delivered | 6.4 |
|---|---|
| Calf width | 7.6 |
| Ease of getting on | 9.4 |
| Breathability | 8.0 |
| Durability | 8.0 |
| Cost per pair | 8.0 |

Questions people actually ask
What compression socks should I wear in pregnancy?
Knee-high, 15-20 mmHg, in a wide-calf cut if you are near a size boundary. That band covers most pregnancy swelling and is easier to get on than firmer socks.
Move to 20-30 mmHg only if 15-20 is not enough, and check with your own midwife or OB first.
When should I wear compression socks in pregnancy?
Put them on before you get out of bed, when swelling is lowest, and take them off in the evening. Applying compression before the fluid has pooled is what makes it work.
They are most useful on days involving long periods standing or sitting, and on flights. Do not sleep in them unless your provider has told you to.
Why can't I get compression socks over my calf?
Because they are sized by ankle and calf circumference rather than shoe size, and pregnancy swells your calf. A sock that fits your foot can easily be too narrow through the leg.
Measure your calf at its widest in the morning and buy a wide-calf cut if you are near a boundary. Rubber washing-up gloves also make a real difference to grip.
Are compression socks safe in pregnancy?
Graduated compression stockings are widely used in pregnancy and are among the measures usually suggested for swelling. The lighter bands are not something people normally need permission for.
Firmer compression, and any use if you have a circulatory condition or diabetes, is worth checking with your own midwife, OB or GP first.
Will compression socks help varicose veins?
They are a standard conservative measure for the symptoms — the aching and heaviness — and pregnancy makes varicose veins more likely for the same mechanical reasons it causes swelling.
They do not make existing varicose veins go away. Many improve on their own in the months after birth; raise persistent ones with your GP.
When is swelling in pregnancy a problem?
Sudden or severe swelling, especially of your face or hands, needs urgent advice — particularly with a headache, visual changes or pain under your ribs, because that combination can indicate preeclampsia.
Swelling in one leg only, especially with calf pain, warmth or redness, needs urgent assessment for a clot. Do not put a compression sock on it and wait.
