Frequently Asked Questions
Compression basics
What are compression socks?
Compression socks are specially engineered socks that apply gentle, graduated pressure to your legs — firmest at the ankle and gradually decreasing up the calf. This design supports your natural circulation and helps reduce leg fatigue and everyday swelling.
How do compression socks work?
The graduated pressure gently supports your veins and muscles, encouraging blood to flow upward toward your heart rather than pooling in your lower legs. That's why legs tend to feel fresher and lighter at the end of a long day in compression socks.
What compression level are your socks?
All of our compression socks are 20–30 mmHg — the same graduated compression level most commonly recommended by professionals and worn by athletes, nurses, and frequent travelers.
Why is 20–30 mmHg the best level?
Compression is measured in millimeters of mercury (mmHg), on a scale that runs from light 8–15 mmHg everyday socks up to 40+ mmHg prescription garments. 20–30 mmHg sits right in the sweet spot of that range: it's strong enough to deliver real, noticeable support — unlike lighter levels, which many people find too mild to feel a difference — yet still comfortable enough to wear all day, every day. Higher levels (30–40 mmHg and up) are typically reserved for specific medical conditions and are usually worn under a doctor's guidance. That balance of genuine effectiveness and all-day comfort is why 20–30 mmHg is the most popular choice for work, sport, travel, and daily wear — and why it's the only level we make.
Who are compression socks for?
Anyone who spends long hours on their feet or sitting still: nurses and healthcare workers, athletes and runners, frequent flyers, tradespeople, office workers, servers, teachers, and anyone who deals with tired, achy legs. Many people simply wear them daily for comfort.
Are there people who shouldn't wear compression socks?
People with certain conditions — such as severe peripheral artery disease, some skin conditions, or nerve issues affecting sensation in the legs — should check with a doctor before wearing compression socks. If you're pregnant, have diabetes, or have any circulation-related condition, it's best to get your doctor's OK first.
Do compression socks help with swelling and tired legs?
Many people wear them for exactly that — graduated compression is widely used to help manage everyday leg fatigue and mild swelling from long periods of standing or sitting. Individual results vary, and persistent swelling is worth discussing with a doctor.
Are compression socks good for flying?
They're very popular with travelers. Sitting still for hours on a flight can leave legs feeling heavy and swollen, and compression socks are commonly worn to help with that. If you have specific health concerns about flying, talk to your doctor.
Do athletes really use compression socks?
Yes — runners, cyclists, lifters, and team-sport athletes wear them during training and for recovery afterward. Many athletes find their legs feel better during long sessions and less sore the day after. 20–30 mmHg is the level most commonly chosen for sport.
Sizing & fit
How do I pick the right size?
Each product page includes a size chart based on shoe size and calf circumference. For the most accurate fit, measure your calf at its widest point. If you're between sizes, size up for comfort or down for firmer compression.
How tight should compression socks feel?
Snug but never painful. You should feel firm, even pressure that's strongest at the ankle. If your toes tingle, go numb, or the sock leaves deep marks or digs in painfully, the size is too small — contact us for a free size exchange.
My calves are wide — will they fit?
Our size charts include calf circumference specifically so you can find a comfortable fit. Measure your calf at its widest point and match it to the chart; when in doubt, go with the calf measurement over the shoe size.
Why do my compression socks roll down or slide?
Rolling usually means the sock is too small (the band is overstretched) or occasionally too large. Check your calf measurement against the size chart, and make sure the top band sits flat about two finger-widths below the knee — never fold the top over, as that doubles the pressure.
Wearing & care
How do I put compression socks on?
The easy method: reach into the sock and pinch the heel, turn it mostly inside-out down to the heel pocket, slip your foot in, then unroll the sock up your leg and smooth out any wrinkles. Putting them on first thing in the morning, before any swelling starts, makes it easier. Since 20–30 mmHg socks are firmer than regular socks, this method makes a big difference.
How long should I wear them each day?
Most people wear compression socks throughout the day — putting them on in the morning and taking them off in the evening. There's no harm in daytime wear for healthy adults; wear them for as long as they're comfortable and helpful.
Can I sleep in compression socks?
They're designed for daytime, when you're upright and gravity is working against your circulation. Most people take them off at night. If you've been advised to wear compression overnight for a medical reason, follow your doctor's guidance.
How should I wash compression socks?
Machine wash cold on a gentle cycle and air dry. Skip bleach, fabric softener, and high-heat drying — they break down the elastic fibers and reduce compression over time. Washing after each wear actually helps the fibers recover their stretch.
How often should I replace them?
With regular wear, compression socks maintain their effectiveness for about 3–6 months. When they start feeling noticeably looser or slide down easily, the compression has relaxed and it's time for a fresh pair. Rotating between multiple pairs extends the life of each.
