Introduction

Compression socks have been around for decades, but they've come a long way from the beige medical stockings your grandmother may have worn.

Today you'll find them on nurses, teachers, travelers, runners, office workers, pregnant women, and anyone who spends long hours on their feet.

But what exactly do they do?

Do they actually work?

And do you need them?

Let's find out.

What are compression socks?

Compression socks are specially designed socks that apply gentle pressure to your legs, ankles, and feet. This pressure improves blood flow, reduces swelling, and supports muscle recovery — all of which are incredibly beneficial during and after during and after long shifts, travel, exercise, recovery, or everyday life.

How do compression socks work?

As the name suggests, compression socks gently compress your legs, promoting better blood circulation and allowing blood to return to your heart more efficiently. Think of compression socks as giving your circulation a gentle helping hand; they encourage blood to travel back toward your heart instead of pooling in your lower legs. Whether you’re sitting, standing, or on the move, compression socks support healthy circulation and improve overall leg comfort.

It's a wonderfully simple concept, one that's backed by decades of use in both medicine and everyday life.

Why do people wear compression socks?

People wear compression socks because they help support circulation and reduce fatigue during long periods of standing, sitting, or travel.

Some examples include:

• work, especially if you stand for long periods of time
• flying, to prevent swelling
• pregnancy, to prevent swelling
• exercise, to support energy and decrease risk of injury
• recovery, to ensure the blood flow to your heart is optimal
• everyday comfort

A nurse's perspective

I spent years watching nurses finish twelve-hour shifts with aching legs, swollen feet, and enough exhaustion to make them question how they'd do it all again tomorrow.

I also watched something else.

The nurses who faithfully wore compression socks usually finished those same shifts feeling noticeably better.

That got my attention.

I actually decided to start Ruby because I understood the value of compression and I wanted to make it look cute and something women would be excited to wear, something to ignite conversation and connection between- in my case specifically- nurses to colleagues and patients.

Who should wear compression socks?

• Nurses & healthcare professionals
  Compression socks help increase energy (as explained previously) and support muscles and tendons to help decrease fatigue and pain that often accompanies those never-ending shifts.
• Teachers
  Teaching frequently requires standing for long periods of time, and compression socks can help reduce fatigue and swelling so your attention can be on the minds you’re looking to build and enrich.
• Retail workers
  Compression socks will help support you while you’re on your feet folding clothes, managing shipments, and dealing with customer nonsense.
• Hairstylists & barbers
  Your attention should be on that new cut and color you’re working on and not distracted by leg pain, fatigue or swelling. Compression socks help eliminate all three.
• Travelers
  As an avid traveler, compression socks are the best when it comes to keeping your feet and legs from swelling. The first time I wore Ruby’s compression socks on a flight I was stoked my toes didn’t look like little sausages haha.
• Office workers
  Don’t be fooled by all those jobs that require you to be on your feet all day- sitting all day is hard on your circulatory system too! Compression socks keep that blood flowing and keeps you from swelling while you sit and do your thing.
• Pregnant women
  I am a mother of three girls. Each pregnancy a challenge, but especially towards the end when you feel like a puffy beluga whale. Compression socks keep your blood flow in top shape to not only reduce that swelling, but also to optimize the flow to your baby.
• Athletes
  Do you look to optimize your athletic performance at all? Try compression socks. By supporting circulation and reducing fatigue, compression socks may help you feel fresher during or after activity.
• Anyone who spends long periods standing or sitting
  In the event that you are on your feet for extended periods of time and not included in the professions or situations described above, you can still benefit from compression socks! And don’t forget about fun events. Do you have a concert to go to and all that was available was general admission? Don’t forget your compression socks, you’ll thank me later.

Benefits of compression socks

• Improved Circulation
  Standing for hours can lead to blood pooling in the lower legs and feet, causing fatigue and swelling. Compression socks help push blood back toward the heart, improving circulation and preventing the heaviness and pain that often develops after a long shift.
• Reduced Swelling and Fatigue
  Compression socks provide pressure on your lower legs which helps move excess fluid out of the tissues. This can significantly reduce swelling and improve energy levels.
• Lower Risk of Varicose Veins
  Constant standing can contribute to the development of varicose veins over time. Compression socks help prevent these unsightly and sometimes painful veins by supporting proper blood flow and reducing vein stress.
• Better Muscle Recovery
  The consistent support provided by compression socks helps reduce muscle vibration and fatigue, leading to faster recovery and fewer aches.
• Enhanced Comfort During Shifts
  Many compression socks are made with breathable, moisture-wicking materials that help keep feet dry and comfortable throughout the day. Some also have padded soles for added support.

Compression levels explained

Common misconceptions about compression socks

You may have heard some of the following rumors about compression socks over the years, and I am here to set the record straight!

Compression socks are only for old people.
Nope. All ages can benefit from compression socks!

They're only for nurses.
Definitely not. Athletes, pregnant women, and a variety of other people can benefit from the use of compression.

They're impossible to get on.
Sometimes...but not always. 😂 If you’re interested in having a little lesson about how to put compression socks on, this article explains it really well. I promise, they’re not as intimidating or frustrating as pantyhose haha.

They're uncomfortable.
Not if they fit properly.

They all look medical.
Girl, have you seen Ruby’s compression socks?

Knee-high socks vs compression sleeves

Knee-high compression socks

Provide graduated compression from your foot to just below your knee.

They're the best choice if you're looking for circulation benefits because they compress the foot, ankle, and calf together.

Compression sleeves

Compression sleeves cover only the calf.

They're popular with runners and cyclists who want calf muscle support while wearing their own athletic socks.

Because sleeves don't cover the foot or ankle, they don't provide the same overall compression as a full compression sock.

Which should you choose?

If you're looking for everyday comfort, work, travel, or swelling relief...

Choose compression socks.

If you're an athlete who specifically wants calf support...

Compression sleeves may be worth considering.

How should compression socks fit?

Compression socks should be snug, that’s part of the reason for all the benefits that have discussed. However, they should not be painful and should never cut off circulation.

How long should you wear compression socks?

Compression socks can be worn regularly, though most people remove them in the evening before bed. If you ever have questions, ask your doctor!

Can you exercise in compression socks?

Yes, absolutely!

Whether you're training for a marathon, heading to Pilates, or hiking your favorite trail, compression socks can be a great companion for exercise.

By supporting healthy circulation, compression socks help move blood back toward the heart more efficiently. This improved blood flow delivers oxygen to your muscles, helping reduce fatigue so your legs feel fresher during and after activity.

Compression socks can also help minimize swelling, reduce muscle vibration, and support recovery after exercise. Many people find their legs feel less heavy and achy after long runs, hikes, or workouts when wearing compression socks.

As an added bonus, high-quality compression socks help keep your feet dry and comfortable by wicking away moisture, reducing the likelihood of blisters during longer activities.

Whether you're walking around the neighborhood or tackling your next big adventure, compression socks are designed to help support every step.

How to put on compression socks

First-time compression sock wearers: be forewarned—putting on compression socks can be a bit frustrating at first. They’re not like regular socks, and that’s by design. Compression socks are made to apply gentle pressure to your legs, which helps improve circulation, reduce swelling, and prevent issues like varicose veins and blood clots. But because of this, they’re tighter and more form-fitting, which can make them tricky to put on, especially if you're new to wearing them.

Don’t worry. With a little practice and the right technique, putting on your Ruby compression socks will become part of your regular routine. Here’s a simple, step-by-step guide to help make the process easier and more comfortable:

1. Choose the Right Time of Day

It’s usually easiest to put on compression socks in the morning, right after you wake up. Why? Because your legs are typically less swollen in the morning after a night of rest. As the day goes on, gravity pulls fluid down into your legs and ankles, which can make your legs slightly larger and make it harder to slide on tight-fitting socks. Alternatively, if you’re using your Ruby compression socks for a specific activity like a long flight, run, or shift at work, put them on just before you begin.

2. Prep Your Legs and Feet

Before you begin, make sure your legs and feet are clean and completely dry. Moisture, lotion, or oil can make it harder for the fabric to grip and slide over your skin. If you’ve just showered, wait a few minutes until your skin is dry, or pat your legs down with a towel.

3. Start by Bunching the Sock

Use both hands to bunch up the sock from the top down to the toe area. Place your thumbs on the inside and fingers on the outside to create a firm grip. (For those familiar with the concept, think of how you’d bunch up a pair of pantyhose before putting them on—same idea.) Once the sock is bunched up, slip your toes in first and begin working the sock over your foot.

4. Pull the Sock Over Your Heel and Up Your Leg

Gently pull the sock over your heel and start moving it up your ankle and calf. Take your time. Make small adjustments to ensure the sock is going on evenly. Avoid pulling too hard in one spot, which can stretch the fabric or cause discomfort.

5. Smooth It Out

Once the sock is fully on your leg, smooth out any wrinkles or folds. Compression socks should fit snugly but not cause pain or cutting into your skin. Check that the top band sits flat and the compression is evenly distributed.

Final Tip: Don’t be discouraged if it takes a few tries to get it right. Like anything new, it gets easier with practice—and your legs will thank you for the support.

Caring for compression socks

Any time you’re dealing with the care of clothing, there are two approaches: the ideal and the practical. I will outline both so you can choose what care regimen works best for your lifestyle and your Ruby compression socks (also lovingly referred to as Rubies)!

The Ideal Approach

Hand washing is preferred. Gently wash your Ruby compression socks by hand in lukewarm water using a mild detergent, and always avoid using bleach or fabric softeners. Air dry flat; always avoid hanging them by their tops as this can stretch them out, and always avoid hanging them on a source of heat (like a radiator) as the excessive heat can damage the elastic fibers.

The rationale for this approach is simple: avoiding friction (ie- the agitation of clothing in a wash cycle or as they tumble dry in a dryer) and heat will increase the longevity of any article of clothing. Avoiding bleach will keep colors bright. Avoiding fabric softeners prevent residue that can reduce the breathability and performance of your Rubies.

But let’s be real- sometimes the demands of life make the practicality of the ideal approach unfeasible! Let’s review a more practical approach:

The Practical Approach

For those who are crunched for time (or just hate laundry and won’t wash anything by hand even if their life depended on it), it’s okay to forgo the ideal approach and use the practical approach to care for your Ruby compression socks instead:

Always wash your Rubies on a delicate or gentle cycle in cold water, inside out, with like colors. As has been discussed before, don’t use bleach or fabric softener; this will help keep the colors of your compression socks bright and true! (Bonus tip: put your Rubies in a mesh bag to avoid excessive agitation, thus keeping them in better shape for longer.)

Even if you need to use a washing machine, please still consider air drying your Ruby compression socks if you have the time. As mentioned before, heat is the enemy of fabric, and you will notice that your socks will stay newer longer by air drying. That said, I know that sometimes you are in a rush and need things (especially laundry) done faster. If you choose to tumble dry your Rubies, make sure the heat setting is on low to maintain the high-quality integrity of the fabric. And, of course, never iron (who irons socks anyway?)!!!

Other things to consider

Regardless of which approach you choose to use to care for your Ruby compression socks, there are a few other factors to consider when caring for them:

FREQUENCY

Make sure to wash your Rubies after each use. It is important to remove oils, sweat, and skin particles that can reduce their elasticity and effectiveness!

…BUT (pause for emphasis on “but”)…

I have received several messages from nurses saying that they *secretly* wore a pair of their Ruby compression socks twice in a row without washing (out of desperation), and their feet didn’t stink! Special thanks to the permanent antimicrobial technology woven into Ruby’s cutting-edge fabric for that small yet purposeful miracle haha.

ROTATE

Having multiple pairs of Ruby compression socks is important to allow for rotation, which can extend the lifespan of Rubies. This isn’t a sales gimmick on my part, it’s just fact- the more pairs you have, the less frequently each pair gets worn, and the longer each pair will last. Wins all around!

REPLACE WHEN NECESSARY

Compression socks lose elasticity and effectiveness over time, and it is recommended that they be replaced every 3 to 6 months depending on how often you wear them. The great thing about Ruby compression socks, however, is even if they lose the compression they still look great! So keep them around to wear when compression may not be priority one. If compression is always your main priority, however, consider replacing them throughout the year. (Note: Also not a sales gimmick, it’s just the way these things work…)

Taking care of your Ruby compression socks helps maintain their compression levels and overall quality, ensuring they continue to provide the support and benefits you need!

Frequently Asked Questions

• Can you sleep in compression socks?
  Yes, but check with your healthcare provider first. For most healthy people it isn't necessary to sleep in compression socks, and your provider can advise you if overnight compression is appropriate for your specific situation.
• Can you wear them every day?
  Absolutely! Many people wear compression socks every day for comfort, support, and to help reduce leg fatigue and swelling.
• How tight should they feel?
  I'm going to blow your mind on this one—they're supposed to feel snug. 😂 They should never be painful or cut off circulation, but that firm hug you're feeling is exactly how compression socks are designed to work.
• How long do they last?
  Most compression socks maintain their best performance for about 3–6 months with regular wear. As the elastic fibers naturally relax over time, replacing them helps ensure you're still getting the intended level of compression.
• Do I need compression socks for flying?
  The answer is no, but flying WITH compression socks is a game changer. Give it a shot on your next flight and be amazed at the reduced swelling and fatigue!
• Do they help varicose veins?
  Compression socks can help relieve discomfort associated with varicose veins. Medical-grade compression is often recommended for treatment, while everyday compression can still provide comfort and support for many people.
• Can healthy people wear compression socks?
  Absolutely! Compression socks aren't just for medical conditions. Travelers, healthcare workers, athletes, teachers, and anyone who spends long hours on their feet can benefit from wearing them.
• Can you wear them while exercising?
  Definitely. Compression socks may help reduce muscle fatigue, improve circulation, and keep your legs feeling fresher during and after exercise.
• Do compression socks make your legs weaker?
  No, not at all.
• Can you put lotion on before wearing them?
  Yes, just allow it to fully absorb before putting your compression socks on (otherwise they’ll be harder to put on).
  

Final thoughts

We spend so much of life taking care of everyone else, pushing through long shifts, long flights, long days, and long to-do lists.
