Compression Socks 101: What They Are, Benefits & How to Wear Them
New to compression socks? Here's everything in plain words: what they are, who wears them, how to pick your pair, and how to put them on, take them off, and care for them.
What are compression socks?
Compression socks are knitted with elastic fibers, so they fit more snugly than regular socks. Venasense socks use graduated compression: the fit is firmest at the ankle and gets gentler toward the knee. It feels like a steady, supportive hug, not a squeeze in one spot.
What does "15–20 mmHg" mean? mmHg stands for millimeters of mercury, the standard unit for measuring pressure. The number tells you how firm the fit is: the higher the number, the firmer the squeeze.
Light
A gentle everyday feel.
Moderate
Comfortable for everyday wear, travel, work, and sports.

Graduated compression gives your legs gentle, steady support from the ankle up. Here's what people notice most:
Lighter legs
Legs that feel lighter and less tired at the end of a long day.
Less heaviness
Less of that heavy-leg feeling after hours of standing or sitting.
Snug support
A supportive fit that feels good during a workout.
Fresh arrivals
Step off a long trip with legs that feel fresher.
Compression socks are a comfort product, not a treatment for any medical condition. If you have a health concern about your legs, talk to your doctor.

How to measure: For socks, place your bare foot on a piece of paper, trace around it, and measure from the tip of your longest toe to the back of your heel. For calf sleeves, measure around the widest part of your calf and the narrowest part of your ankle. For arch support socks, measure around the narrowest part of your ankle.

How to put on compression socks
Take off rings, watches, and bracelets, and watch out for long nails, since they can snag the fibers.
Put them on in the morning, when your legs feel their best.
Reach inside the sock, grab the heel, and turn the sock inside out down to the heel.
Slide your foot in and line up the heel so it sits in the right spot.
Roll the rest of the sock up your leg a little at a time. Don't yank from the top.
Smooth out any wrinkles. The top should sit just below the knee, not folded over.
How to take off compression socks
When to wear compression socks
During the day
Put them on in the morning and wear them through your waking hours.
Flights & long trips
Put them on before you leave and keep them on until you arrive.
Workouts
Wear ankle socks and calf sleeves during your activity, then take them off.
At night: off
Lying down, your legs don't need the extra support, and your skin gets a break. Want to wear them overnight? Check with your doctor first.
Care and when to replace them
- Hand wash in cold water with mild soap.
- Dry flat in the shade. Don't tumble dry or hang them from clips.
- Skip bleach and fabric softener, since heat and harsh products wear out the elastic fibers.
- Own two or three pairs and rotate, so each pair rests between wears.
months
Replace your pair about every 6 months for the best compression, or sooner if it feels loose or slides down.
Check with your doctor first if…
Compression socks aren't right for everyone. Talk to your doctor before wearing them if you have:
- Circulation problems in the arteries of your legs (such as peripheral artery disease)
- Diabetes with nerve damage or reduced feeling in your feet
- A heart condition, such as heart failure
- A skin infection, open wounds, or very fragile skin on your legs
- An allergy to elastic or other sock materials
Also check with your doctor if you're pregnant, have a diagnosed vein or leg condition, or are thinking about a firmer compression level. If a pair causes pain, numbness, tingling, or skin changes, take it off.
