Pregnancy is full of changes; both exciting and unexpected. As the body adjusts to supporting a growing baby, it’s common to notice things feel different, especially in the legs.
For many moms-to-be, that shows up as swollen feet, aching calves, or legs that feel heavy and tired by the end of the day. You might notice your shoes feeling tighter by midday, or your ankles looking puffier than usual. These changes are a normal part of pregnancy.
As your blood volume increases and your body carries more weight, circulation in the legs can slow down. That’s often what leads to swelling, discomfort, and that tired-leg feeling.
So what can you do about it?
One option many pregnant women turn to is compression socks. They’re designed to apply gentle, graduated pressure to the lower legs and feet, encouraging blood to flow back toward the heart instead of pooling in the legs. That added support can make a noticeable difference when it comes to swelling, and everyday comfort.
To understand why compression socks can be so helpful during pregnancy, it helps to first understand what’s actually happening inside your body.
Why Do Legs Swell During Pregnancy ?
Swelling during pregnancy is very common, especially in the second and third trimesters. While it can be uncomfortable, there’s a clear reason your body reacts this way. Here’s what’s happening:
-
Your body produces significantly more blood and fluid to support both you and your growing baby. That extra fluid has to go somewhere.
-
Pregnancy hormones like relaxin which helps your body prepare for delivery make your ligament more flexible
-
Your growing uterus puts pressure on the veins in your pelvis, making it harder for blood to travel back up from your legs.
All of this can lead to swelling called oedema in your feet, ankles, and calves, and sometimes even discomfort or heaviness.
How Compression Socks Help During Pregnancy
Compression socks don’t stop these changes from happening, but they can help your legs handle them better.
→ They Improve Circulation
Compression socks apply gentle, graduated pressure to the legs. This helps blood move upward toward the heart more efficiently instead of pooling in the lower legs.
→ They Reduce Swelling and Discomfort
Many pregnant women notice less swelling in their feet and ankles, along with reduced leg fatigue, when they wear compression socks during the day.
→ They Can Help With Varicose Veins
Pregnancy increases the likelihood of developing varicose veins, those visible blue or purple veins that may feel sore or tender. Compression socks help support vein function and may reduce how noticeable or uncomfortable they become.
→ They Make Travel More Comfortable
Whether you’re flying or taking a long car ride, compression socks help keep circulation moving and can limit swelling caused by long periods of sitting.
Choosing the Right Compression Socks for Pregnancy
Not all compression socks are the same, and during pregnancy, comfort and fit matter just as much as support.
Here are a few things to keep in mind when choosing the right pair.
-
Compression Level (mmHg)
Compression strength is measured in millimeters of mercury (mmHg). The higher the number, the firmer the pressure.
-
15–20 mmHg: Light to moderate compression that works well for everyday pregnancy swelling and leg fatigue.
-
20–30 mmHg: Moderate compression that may be helpful if swelling is more noticeable or persistent.
Most pregnant people feel comfortable starting with a lower compression level unless their doctor recommends something stronger.
-
Length
The right length depends on where you feel discomfort.
-
Knee-high socks are often enough for swelling in the feet, ankles, and calves.
-
Thigh-high socks provide compression higher up the leg and may be helpful if varicose veins extend above the knee.
If you’re unsure, knee-high compression socks are usually a practical place to start.
-
