We’ve all been there: you find the perfect pair of socks, but you hesitate at the "Add to Cart" button. What if they don't fit? What if they’re too tight? When it comes to compression socks, size isn't just about comfort, it’s about performance. To get the circulation-boosting benefits you're looking for, the fit needs to be just right.
The good news? Finding your perfect match takes less than 60 seconds. Since each of our FITLEGS products has a specific size guide tailored to its unique weave and compression level, all you need is one quick measurement.
Why the Ankle?
While standard socks go by shoe size, compression socks are different. The most critical point of pressure is at the narrowest part of your ankle. Measuring here ensures the graduated compression works exactly as intended.
How to Measure at Home (2 Easy Ways)
Good news: you don't need a professional fitting to get started (though this can be helpful for our AES medical products). The secret to a great fit is all in the ankle, which is where that vital graduated pressure begins.
For our AES and Everyday Life socks, we also look at how your calf size compares to your ankle to decide if you should size up or down. Since every sock is built differently, please double-check the size guide on the specific product page.
Ready to measure? Just grab one of these common household items:
Option 1: Fabric Tape Measure (Most Accurate)
- Find your ankle bone and measure two finger-widths above it.
- Wrap the tape measure snugly (but not tightly) around that spot.
- Note down the circumference in centimetres.
- Compare your ankle measurement to the size guide on the specific product page you’re viewing.
Option 2: String & Ruler (No Tape? No Problem!)
- Wrap a piece of string, yarn, or even a strip of paper around your ankle at that same spot (two fingers above the ankle bone).
- Mark the exact point where the end meets the rest of the string.
- Lay the string flat against a ruler or a standard metal tape measure to get your measurement.
- Check that number against our sizing guide to find your match.
Pro Tips for a "Just Right" Fit
- Measure in the morning: Your legs are usually at their most "natural" size first thing in the day before any swelling sets in.
- Trust the guide: If you are right on the border between two sizes, we generally recommend sizing up for comfort.
- Check every time: Different styles (like everyday life vs. sports compression) may have slightly different guides. Always click the ‘Size Guide’ link on the specific product page!

Frequently Asked Questions:
Q: My shoe size says medium, but my ankle measurement says Large. Which do I trust?
A: Trust your ankle measurement. Typical socks tend to use shoe size for measurement because this provides a guide for the length of your foot. Compression socks work slightly differently, because the function of the sock depends entirely on the circumference of your ankle and calf. Forget shoe size and use the specific size guide on each product page.
Q: Can I return FITLEGS products if they're the wrong size?
A: Unfortunately, we only accept returns on unopened products. For hygiene reasons, we are unable to accept returns on open or used products. We encourage customers to do these simple and quick measurements at home to ensure a perfect fit before purchasing.
Q: Will they shrink in the wash?
A: Our socks are designed to hold their shape, but high heat can damage the elastic fibers. To keep your fit perfect, we recommend washing in cool water and air drying only.
Q: How tight should they actually feel?
A: They should feel like a firm hug around your legs. You should feel the pressure, but it should never be painful, cause numbness, or dig in to the skin. If they are too tight, you likely need a size up!
