Compression Sock Sizing Made Easy with Sistasaidso+

Compression socks can work magic: boosting circulation, reducing swelling, and keeping that end-of-day fatigue in check. But only if they fit properly. Too loose? No support. Too tight? Say hello to discomfort (and possibly cutting off circulation – no thanks). The secret to reaping all the benefits? Nailing your size.

At Sistasaidso+, we believe feeling supported starts from the ground up. So we’ve put together a no-fuss guide to help you find your perfect fit - just you, a tape measure, and zero guesswork. Let’s get into it.

 

Why the Right Size Matters

Compression socks are designed to apply gentle, graduated pressure, tightest at the ankle and gradually decreasing up the leg. That pressure needs to exist in the right places to be effective. If your compression socks are too tight, they can be uncomfortable or even restrict circulation. If they’re too loose, they won’t offer the support your legs need(pretty pointless really!). Getting the right fit means better results and all-day comfort.

 

How to Measure for Compression Socks

Measuring your legs for compression socks is easier than you think, and it only takes a few minutes. Here's what you'll need:

• A soft measuring tape
• A chair
• A quiet moment to yourself (yes, they still exist)

Take a seat with your feet flat on the floor, and measure around the widest part of your calf. This is the key to finding the right balance – firm enough to stay up, but not too tight.

Sista Tip: Try to take your measurements first thing in the morning when your legs are least swollen. Trust us, it makes a difference.

 

What About Foot Size?

When it comes to compression socks, we always prioritise calf measurement to ensure the best fit. Foot size is still important, but secondary. Compression socks should feel firm when you first put them on — that’s how you know they’re doing their job.

 

Choosing Between Two Sizes

If you’re between sizes, go with the one that best matches your calf measurement. This ensures you’re getting the right level of compression where it matters most. Foot size comes next, and we’ve designed our socks to work across a range.

So, How Should Compression Socks Feel?

Compression socks should feel firm and supportive from the moment you put them on. They’re not meant to slide on like regular socks - if they do, they’re probably too big!

If they go on too easily or start slipping down during the day, try a smaller size. If they’re a serious struggle to get on or leave deep marks, sizing up is likely the way to go.

 

Common Fit Issues (and What to Do About Them)

1. Struggling to Get Them On?

Compression socks are meant to feel firm but if you’re finding it hard to get them on, you’re not alone. A sock aid can help, especially if mobility’s an issue. Pro tip: try putting them on first thing in the morning when your legs are less swollen.

 

2. Socks Feel Too Loose or Too Tight Around the Foot

This is more common than you think. If your foot feels slightly too small or large in the sock, but the leg fits well, you’re likely still in the right size. 

 

3. Socks Losing Their Stretch?

Compression socks don’t last forever, but a little care goes a long way. To get the most out of your pair:

• Wash after each wear
• Use a gentle cycle at 30-40°C
• Avoid hot water and fabric softeners
• Air-dry flat - no dryers, please!

This helps maintain their shape, stretch, and compression level, so you get more wear, more value, and more support out of every pair.

 

Common Sizing Mistakes To Avoid

 

Guessing Based on Shoe Size

Compression sock sizing isn’t one-size-fits-all. Your shoe size might be a starting point, but proper fit heavily depends on your leg shape and measurements.

Measuring at the Wrong Time of Day

Legs naturally swell as the day goes on. For the most accurate fit, grab the measuring tape first thing in the morning.

Pulling the Tape Too Tight

The tape should be firm, but not digging into your skin. You want real numbers, not compressed ones, to avoid getting a preview of what too-small socks will feel like.

 

You Deserve the Right Fit

Finding your perfect size doesn’t have to be stressful. With a few quick measurements and the right tools, you’ll be set for all-day comfort and proper support. Whether you're wearing compression socks for long shifts, travel, pregnancy, or recovery, the right fit changes everything.
