Do long days at work leave you with painful, swollen ankles? Pregnancy hormones or postpartum recovery making you feel uncomfortable with heavy legs and slow circulation? Long flights causing your feet to go numb or legs to swell?

Swelling in the lower limbs is a real pain! It can be caused by poor blood flow, heat, lack of movement, or other factors that may lead to complicated health conditions. Luckily, edema (swelling) can be addressed by stimulating peripheral blood flow, and you may not need much more than a pair of therapeutic compression socks. At Vim & Vigr, graduated compression socks for swelling relief are more than just an effective medical tool - they offer stylish support and comfort through designs and colors you’ll love to wear.

Read on to find out why your legs and feet swell, how to combat the main causes, and why you should turn to wearing compression socks (you’ll learn how to make the best choice for you).

The most common causes for leg and foot swelling include prolonged sitting, standing, or walking; pregnancy or postpartum hormonal and blood volume changes; certain medications, medical conditions, or surgery recovery; even the heat and fluid retention.

Sitting for long periods of time without moving puts pressure on the lower limb veins and causes gravity to push blood down into your legs, which reduces venous return (where the blood circulates back up towards the heart). This typically happens to travelers on longer-haul flights, who tend to not move around a lot in a small, pressurized space. The CDC warns that this type of travel raises the risk of blood clots or deep vein thrombosis.

But it’s not just traveling long distances that takes its toll on peripheral circulation. More often than that, we sit for too long at our desks and allow our legs to become heavy, without getting up to move regularly. Medical research has found that blood will pool around the ankles, causing swelling and discomfort. And surprisingly, the same happens when we are on our feet all day! It’s why nurses, hairdressers, or construction workers often use compression socks to stimulate leg circulation and energize their lower legs. In fact, swollen legs because of standing at work have been documented heavily, including in an often cited research paper from 2015 quoting health risks and suggesting the use of interventions including compression hosiery.

Finally, long walks or hikes are great for the body and soul but can have a negative impact on the lower limbs for some. Walking is often credited with reducing swelling, but the opposite can be true for people with certain health conditions. Sometimes, increased fluid intake can cause fluid retention and swelling (such as in some extreme cases, like an ultra endurance triathlon). Other times, poor circulation can cause your feet to swell, or you could be suffering from heat edema.

Expecting mothers also experience swelling in their legs and ankles, among other sources of discomfort. Fluid build-up or lack of moving contribute to this. One medical study found that compression socks prevent edema in your lower legs when pregnant, reducing pain, and increasing quality of life.

Another study found that compression garments reduce dizziness and nausea in pregnant women. These studies show us that compression socks can improve the quality of life in pregnancy by reducing swelling and improving other painful conditions. Additionally, during the postpartum period, many women struggle with swollen legs and feet because of lack of movement (particularly in the case of longer periods of bed rest, such as after a C-section delivery).

Certain medications, because of how they affect the body, can cause swelling and edema in the lower legs. These include:

• Calcium channel blockers (like the drug nifedipine), which increase the risk of leg swelling (patients taking them are 10 times more likely to develop edema)

• Hormonal birth controls (like those containing estrogen) are linked to increased risk of blood clots in the legs, which can cause dangerous swelling

• Cancer treatment (chemotherapy)

• Non-steroidal anti-inflammatory drugs (NSAIDs)

• Dopamine agonists

• Nitrates

• ACE inhibitors

• Insulin

• Antipsychotic medications

If you are taking any of these, consult with your doctor about your edema symptoms and the possibility of reducing them by wearing compression socks.

A key clinical report states that the following medical conditions increase the risk of foot and ankle swelling or peripheral edema:

• Vein and artery conditions like deep vein thrombosis (aka blood clots), compartment syndrome, or chronic venous insufficiency

• Heart conditions like heart failure, pericarditis, or pulmonary hypertension

• Liver failure or cirrhosis

• Kidney failure

• Malnutrition or vitamin deficiency

• Allergic reactions

• Cancer

• Lipedema

If you are not sure why swelling or edema is occurring in your legs, seek the advice of a medical practitioner. You should always consult with a medical specialist if swelling starts suddenly and does not go away naturally.

Temperature can affect blood circulation and cause fluid build-up in the lower legs. This is because veins tend to expand to help more blood travel through to the skin, to release heat and cool you down. Research has shown that heat edema is more likely to occur when people are also engaged in some of the above scenarios, like standing or sitting for long periods of time in high temperatures.

Swelling in the feet and ankles is caused by blood or fluid pooling at the extremities. This, in turn, is a result of poor circulation, the pressure of gravity, or of extra blood volume (in the case of pregnancy and postpartum). Graduated compression socks are designed to address this problem specifically; through their tighter grip at the lower end that slowly releases pressure upwards, they stimulate blood flow back towards the heart to negate the effects of gravity.

Compression socks also support the muscles and veins, which works in two ways:

• They take some of the pressure or impact off the lower legs. Supporting the muscles, compression socks reduce the impact of standing, walking, or running on hard surfaces. They also lighten the pressure on the blood vessels.

• They also massage and soothe the lower legs, helping you recover from efforts or reduce fatigue while standing or walking.

As a result, nurses wearing compression socks were found to have less pain and edema than those who did not. And, in a study specifically on hairdressers, compression wear was found to reduce pain, swelling, and fatigue - even going as far as to report that overall quality of life was improved.

Studies and anecdotal evidence agree on multiple benefits of wearing compression for the lower legs:

• Boost in blood flow, avoiding the creation of blood clots and further swelling

• Gradual reduction in swelling and pain

• Protection from cuts, grazes, or other hazards – especially helpful for those with reduced mobility or for people with diabetes

• General feeling of wellbeing and lighter legs

• Support during physical activities – better supporting muscles in the lower legs and the ankles

• Improved muscle recovery and athletic performance

So, how can you pick the best compression socks for swelling? The key decision criterion is that these socks need to match your lifestyle and comfort preferences, not the other way around. To do this, you need to first understand the pressure levels they will apply to your legs.

• 15-20 mmHg socks offer mild compression, which is great for daily wear. Wear them to prevent swelling in the first place, while experiencing a soothing, supporting sensation in the lower legs. These are also good if you suffer from mild edema regularly (e.g., during hot days or long travel days).

• 20-30 mmHg socks provide moderate compression, recommended by doctors when you go on long haul flights, are at risk of blood clots, or are recovering from surgery, among other scenarios. The difference from 15-20 mmHg is notable: the socks feel tighter and the impact is more immediate. These are also called “medical compression socks” and, although they are available to buy without a prescription, we recommend you discuss wearing them with your doctor.

• 30-40 mmHg socks are also known as “medical-grade” and apply the most compression to the lower legs and feet. They are only available by prescription, so a doctor will usually ask you to wear them when you have certain health conditions or severely impaired mobility (e.g., you are bedridden for weeks at a time).

In addition to the pressure level of your compression socks, you’ll want to reach for a pair that looks and feels good depending on your activity levels, outside temperature and humidity levels, and of course - where you’re wearing them!

At Vim & Vigr, we know that swelling relief isn’t just needed when you’re sitting at home. The more you wear your compression socks, the more effective the prevention will be and you can enjoy lighter, more energized feet and legs at work, on a plane, or while recovering from childbirth.

Here are the criteria to check off when you’re buying your socks.

Choosing a fabric is key for breathability and comfort: you want a pair of compression socks that doesn’t make your feet sweat, smell, or develop blisters.

• Cotton is a great everyday choice: it’s soft, breathable, and comes in lots of fun colors and patterns. But it doesn’t wick away moisture so well, so we wouldn’t recommend it for playing sports or going on hikes.

• When to wear: At the office, at home relaxing, or out meeting friends

• Nylon is sleek and flexible, moving seamlessly with your body. That’s why nylon blends are so good in sports clothing. Vim & Vigr nylon socks are made with a multi-dimensional weave to ensure breathability and comfort.

• When to wear: When working out or relaxing after a session.

• Bonus: Toe seams bothering you in tight shoes? We’ve developed the seamless toe collection to help with that! Same great compression, even more comfortable.

• Extra help: Moisture-wick nylon has a higher needle-count than our regular nylon blends and it’s designed to draw the sweat and moisture off your skin. Perfect for hotter temperatures.

• Merino wool is known for its great temperature adaptability: it will keep your feet cool when it’s hot out, and warm in the winter chill. Soft and flexible, it’s also hypoallergenic and antibacterial (avoiding any unwelcome odors!)

• When to wear: On hikes and long walks; for winter sports; if your feet need a bit of extra TLC.

• Bonus: Wear merino wool compression socks if you have sensitive skin or you’re prone to infection or allergies - the antibacterial fabric is great for keeping skin healthy.

Depending on where you plan to wear compression socks for swelling, your personal preferences, and various other factors, the classic knee-high socks may not meet your requirements. But you can still benefit from graduated compression with other garments:

• Wide calf compression socks are, as the name suggests, designed for wider calves. Many people struggle to find the right sizes for them because compression socks prove too tight across their calf muscles. With wide-calf sizing, we cater to your needs while also offering a match against your shoe size (so it’s not one-size-fits-all!). All you need to do is measure your calf circumference: if it’s over 17”, check out our wide calf collection and our sizing charts to find your match.

• Open toe compressions socks leave the toes to breathe, but still deliver a tight, stabilizing grip on the ankles and up the lower legs. They’re great for people looking to wear sandals or flip flops in summer, or if you have sensitive toes or a condition you need to tend to.

• Compression tights are another option for those times when you want full leg cover or compression benefits up the leg and around the pelvic area, too. You can wear these under dresses and skirts, with tunics and T-shirts, when you’re relaxing or working out!

Not sure which anti-swelling compression sock solution applies to your case? Here are some of our most encountered scenarios and what the experts suggest you should wear in each case.

The key to getting the most out of your compression socks is to buy the right size, fabric, and design for your needs in the first place. Then, wearing them right (so they fit well and don’t impair your circulation), and easing yourself into compression wear gradually, are also important elements.

Sizing is crucial for compression to work well. If your socks are too small, they will be tight, cut off your circulation, cause pain, and maybe leave marks. If they are too large, they will simply not work (and can roll down the legs, causing frustration).

To get the right size, use our guide on every product page and start by measuring your calf circumference. Then map against your shoe size and you’ll be ready to go!

But remember: if your socks feel uncomfortable, too tight or too loose, you may not have the correct size. Go up or down according to your needs.

Use our sizing guide to find the best compression socks for swelling.

To keep your socks in good condition and ensure they stay comfortable and effective, a few tips on wearing and caring for them:

• Start off by wearing your compression socks for 2-3 hours until you’re comfortable with the sensation of therapeutic pressure; then, gradually increase the time you spend in your socks, as needed.

• Be careful donning the socks and taking them off. Here’s a handy guide to follow when you first put them on.

• Wash your socks after every wear, in lukewarm or cold water, and with regular detergent. Don’t add bleach or softener. Your socks will dry naturally, so just hang them up (don’t use a drier).

• Never put socks on immediately after you’ve applied lotion or body oil as those substances can damage the fibers.
