What do compression socks do? Compression socks for nurses are the ultimate luxury. Compression socks are also great for people with diabetes, those with varicose veins, or anyone needing a little extra support while standing for long hours. The right pair of high-performance compression socks contour the shape of your legs while providing all-day comfort. Discover the many benefits of wearing compression socks today.

What Do Compression Socks Do for Blood Circulation?

Compression socks are designed to apply pressure to your lower legs and increase blood circulation, which helps to maintain proper blood flow to the heart and throughout the body. The improved blood circulation also reduces discomfort and swelling, which is ideal for nurses, construction workers, postal workers, and anyone else whose job requires a lot of standing. For compression socks that you can wear on the job, check out our 15-20 mmHg Cushioned Compression (Nylon) - OTC socks that provide all-day compression where you need it most.

What Do Compression Socks Do for Athletes?

Compression socks fight muscle oscillation, which makes them an excellent choice for athletes like runners. Muscle oscillation is the muscle movement that occurs when your foot hits the ground and you can feel the vibration through your body. Compression socks enable runners to experience less side-to-side muscle movement in their legs when wearing the socks while running.

What Do Compression Socks Do for Blood Clotting?

For those with a blood clotting disorder, compression socks help prevent Deep Vein Thrombosis (DVT), a medical condition in which a blood clot forms in a deep vein. The pain and swelling caused by DVT is not only uncomfortable but, should a blood clot make its way to your heart, it becomes life-threatening. Compression socks are a great way to help fight the development of DVT by keeping your blood circulating.

What Do Compression Socks Do for Restless Leg Syndrome?

Restless Leg Syndrome (RLS) is defined as a nearly irresistible urge to move the legs, commonly experienced in the evenings and while sitting or lying down. Unfortunately, RLS can disrupt sleep and generally worsens with age. Fortunately, we offer our 20-30 mmHg Cushioned Compression (Nylon) - OTC socks. Wearing these compression socks at night is a great way to fight RLS and its symptoms. They offer 20-30mmHg of graduated compression and feature extra cushioning in the heel, toe, and arch should you want to get up and walk off the urge to move your legs.

What Do Compression Socks Do for Swelling?

Whether as a post-surgery suggestion from the surgeon or to fight the swelling in your legs during pregnancy, compression socks are designed to increase blood circulation while applying the appropriate compression gradients. For those recovering after surgery, this is essential. Compression socks keep your legs from expanding and swelling and help push fluid out of your legs while you rest. 

Most expecting mothers will experience signs of swelling in their ankles and legs within the first four months of pregnancy. You may even experience a pulling sensation in your calves and blood stagnation. Wearing compression socks helps reduce these symptoms during the pregnancy period. Our 15-20 mmHg Merino Wool Cushioned Compression - OTC socks provide all the benefits of compression with superior, soft material making them ideal during pregnancy.

The Perfect Fit Starts With the Right Size.

Your sock size shouldn’t be a guessing game. Our socks range from small to double XL, but the best way to know the perfect fit for you is to match your shoe size to the chart on the left. That way, you’ll know the size you select will give you the fit and feel you expect.

Between sizes? Go with your gut, but rest assured that your socks will still fit great. If you receive your order and find yourself wishing you’d gone up or down a size, just let us know. We’ll happily send you replacements for your preferred size.

Concerned about laundry mix-ups? All FITS® socks are coordinated by color and size, based on the colors you see on the size chart. So, you won’t have to worry about mixing up your sizes with the other FITS® wearers in your home. (But stray socks mysteriously going missing in the dryer? Unfortunately, we can’t help with that.)

How Do You Determine Sock Size?

Sock sizes are typically measured in inches, not by your shoe size. So, a sock size 6-8 will comfortably fit someone whose feet are between six and eight inches long. However, at FITS®, we make it easy for you to choose the ideal sock size without having to measure your foot. Simply use our sock size conversion chart based on your shoe size to select the right fit for you. 

How Do You Measure Your Foot for Socks?

To measure your foot for socks, measure the length from the heel of your foot to the tip of your longest toe. The measurement in inches correlates to your sock size. For example, if your foot is 10 inches long, a sock size 9-11 should fit you comfortably. At FITS®, you can skip this step and find your sock size based on your shoe size using our conversion chart. 

What Is the Sock Size Conversion?

The sock size conversion refers to sock size compared to shoe size. While all companies may vary slightly on which size socks to purchase based on your shoe size, you can always measure your foot to find the right fit for you. 

What is Sock Size to Shoe Size?

Because sock sizes are determined by the length of your foot in inches vs. your shoe size, shoe and sock sizes differ. The FITS® sock size to shoe size conversion is as follows:

Knowing this makes it easy to choose the ideal sock size based on your shoe size without measuring your foot. 

What Age is Sock Size 9-12?

Sock sizes typically don’t correlate with age. For kids, age can be a general indicator of what size sock they’ll need, but everyone is different. An adult sock size 9-12 fits anyone whose feet are approximately nine to twelve inches long. For kids’ sock sizing, check with the company to find exact details to ensure your little one gets the perfect fit.
