Over the past few years, compression socks have gone from being a tool mostly recommended by doctors to a wellness staple that’s infiltrated social media, fashion, and even pop culture. They’re used for everything from chronic venous insufficiency (CVI) to long flights, and their popularity has even led to curated lists like the New York Times Wirecutter’s 7 Best Compression Socks for 2025. But with so many claims about what they can do, it’s important to separate the hype from the real health benefits.
Below, we’ll break down how compression socks work, what conditions they can help manage, when not to use them, and what to look for if you’re buying a pair over the counter.
How compression socks work: veins, circulation, and beyond
Think of compression socks as a gentle hug for your legs. That steady squeeze makes your veins a little narrower, which helps blood move more quickly back toward your heart instead of pooling in your feet and ankles. This boosts circulation, reduces swelling, and gives your tired legs a break. By shifting some of the blood from surface level veins into deeper ones, compression socks also free up space in your tissues, which helps stop that heavy, achy feeling that builds up over the day.
Medical conditions that warrant compression sock usage
Chronic Venous Insufficiency (CVI)
When your leg veins can’t pump blood efficiently, swelling and discomfort often follow. Slipping on compression socks first thing in the morning, before gravity gets the best of you, can make a big difference. Check out our Facebook post for quick facts that can help!
Varicose Veins
Compression socks don’t just ease the discomfort of varicose veins. They may also help slow new ones from forming. They’re especially useful if you spend long hours standing or on the move.
Deep Vein Thrombosis (DVT)
After treatment for a blood clot, compression can support healthy circulation and may lower the risk of another one forming. It’s a simple step that helps keep recovery on track.
Chronic Illness and POTS
Living with conditions like diabetes, autoimmune disorders, or Postural Orthostatic Tachycardia Syndrome (POTS) often means dealing with swelling or fatigue. Compression socks can reduce blood pooling and help make everyday activities a little easier.
Pregnancy and Postpartum
Many expectant moms turn to compression socks by the second trimester to manage swelling. By the third trimester, they often become part of the daily routine. After delivery, compression can lower deep vein thrombosis risk (especially after a C-section) and support circulation as your body adjusts.
What if I don’t have a condition?
You don’t need a diagnosis to benefit from compression socks! Plenty of people wear them for comfort, performance, or prevention.
On the job
-
Standing professions: Nurses, teachers, and retail and hospitality professionals swear by them for keeping swelling at bay.
-
Sitting professions: Office workers and drivers benefit too. Compression paired with short movement breaks keeps blood flowing when you’re desk bound.
Seasonal comfort
-
Hot weather: Breathable, lightweight fabrics are your friend. Many people wear them in the morning, take a break during peak heat, then reapply later.
-
Cold weather: Winter is the easiest time to wear compression. It feels cozy, and circulation support is extra valuable when blood vessels naturally tighten in the cold.
Traveling
Compression socks are practically a must for long flights or road trips. Put them on before you board to keep blood moving, especially on trips longer than four hours. Many doctors suggest leaving them on for a few hours after arrival, too.
Working out
Athletes often use compression before, during, or after workouts. The biggest benefits? Wearing them in the recovery window (within 1–2 hours after exercise) can reduce soreness, flush out waste products, and support muscle repair.
Who shouldn’t use compression socks?
Compression socks aren’t for everyone. Skip them, or talk to our team first, if you have:
-
Severe heart failure
-
Skin infections or cellulitis
-
Advanced neuropathy (where you can’t feel tightness or pain)
-
Open wounds or untreated ulcers
Choosing over the counter compression socks

Compression level: NOTE: We strongly suggest talking to one of our doctors before using moderate or firm compression socks.

Moderate (15–20 mmHg): Travel, standing jobs, or mild varicose veins.

-
-
Fit: Measure in the morning when swelling is lowest for the most accurate size.
-
Fabric: Go breathable and moisture wicking for all day comfort.
-
Style: Knee highs are most common, but thigh high or pantyhose styles may be recommended for specific conditions.
