Compression socks guide.
Which compression strength is right for you?
"mmHg" explained plainly. No medical degree required.
What does "mmHg" mean and why does it matter?
"mmHg" stands for millimeters of mercury, the same unit used to measure blood pressure. In compression socks, it tells you how much pressure the sock applies to the feet and legs. A higher number = more compression. The right level depends on why you're wearing them.
Most people who need compression socks for everyday reasons, like travel, long shifts, leg fatigue, mild swelling, do well with 15-20 mmHg. Medical conditions sometimes require more. Here's how to figure out where you land.
The four main compression levels:
8-15 mmHg
Light compression
Good for mild leg fatigue, travel under a few hours, and people who want a little extra support without a strong compression feeling. Available over the counter. Suitable for almost anyone.
Who it's for: first-time compression sock users, light travel, mild discomfort during long days.
15-20 mmHg
Mild to moderate compression
The most common everyday level. Strong enough to make a real difference in circulation and swelling, comfortable enough for all-day wear without a prescription. All of Mode Compression socks are 15-20mmHg.
Who it's for: nurses, travelers, pregnant women, people who stand all day, mild varicose vein symptoms, everyday leg health, athletes using compression for recovery.
20-30 mmHg
Moderate to firm compression
Available over the counter, but more often doctor-recommended. Used for varicose veins, moderate edema, post-surgical recovery, and DVT prevention in higher-risk patients.
Who it's for: people with varicose veins, post-surgical recovery, higher-risk DVT prevention. Worth checking with your doctor first.
30-40 mmHg
Firm compression
Typically prescription. Used for severe chronic venous insufficiency, severe lymphedema, and significant varicose veins. Requires proper measurement and often a prescription from a healthcare provider.
Who it's for: people with significant medical conditions affecting venous return. See your doctor.
Our socks are 15-20 mmHg.
15-20 mmHg is the sweet spot for most everyday compression needs. Strong enough to meaningfully improve circulation, reduce swelling, and cut down on leg fatigue. Comfortable enough to wear for a 12-hour shift, a transatlantic flight, or every day without thinking about it.
If you're a nurse, a frequent traveler, pregnant, on your feet all day, or just someone whose legs feel heavy and tired by the end of the day, Mode Compression was built for you. No prescription needed.
Questions?
What mmHg compression socks should I buy?
For most everyday use, travel, standing all day, leg fatigue, mild swelling, 15-20 mmHg is the right starting point. It's the most commonly recommended level for everyday compression needs, strong enough to make a real difference, and available without a prescription. For specific medical conditions like varicose veins or lymphedema, consult your doctor about whether you need more compression.
Is 15-20 mmHg enough for everyday wear?
Yes, for most people. 15-20 mmHg is the most commonly recommended level for everyday use. It's strong enough to improve circulation and reduce swelling, and comfortable enough for all-day wear without a prescription.
Do I need a prescription for compression socks?
For 15-20 mmHg and below, no prescription is needed. Higher levels (20-30 mmHg and above) are available over the counter but are often doctor-recommended. 30-40 mmHg typically requires a prescription and professional fitting.
Can I wear 15-20 mmHg if I have a medical condition?
15-20 mmHg is generally safe for most people, but if you have a medical condition or other circulatory issues, you should always consult with your doctor before wearing any compression.
Is higher compression always better?
Not necessarily. Higher compression means more pressure and more pressure isn't better if it means you won't wear them consistently. 15-20 mmHg is generally recommended for most everyday use cases. If you have a medical condition or reason to believe you should be wearing stronger compression, you should always consult with your doctor first.
What's the difference between graduated and uniform compression?
Graduated compression is tightest at the ankle and decreases up the leg, this is how medical-grade compression socks work, and it's what Mode Compression uses. Uniform compression is the same pressure throughout, which is harder to put on and less effective for circulation.
