Are COS Shoes True to Size for Women? A Fashion Enthusiast’s Guide

As a fashion enthusiast, I've recently become obsessed with COS shoes.COS brings effortless style to clothing and shoes with its minimalist, sleek look. But truth be told, when buying shoes online, the first thing every girl wants to know is: Are COS shoes true to size for women? Today, I'm going to use my own personal experience, plus some research I've done, to provide you with some advice that will help you solve your sizing confusion and buy the perfect pair of shoes without any hassle!

COS Women’s Shoe Sizing: Easy, But a Bit Misleading

Let's begin with the undeniable appeal of COS shoes. They're a feast for the eyes with their sleek lines, good materials, and hipster chic that just transforms an outfit from meh to magic. But sizing? Ah, I've learned the hard way that COS doesn't use the typical "true-to-standard" sizing of most brands. Since most of their shoes are produced in Europe, with their European aesthetic, their sizing adheres to EU measurements rather than the US measurements we're familiar with. Simply put, you can't just use your usual size and hope for the best; you'll need to do some research to get it right.

My Sizing Slip-Up: A Fashion Story of Trial and Error

Okay, time for a story! I have a foot that's about 24.5cm—not terrible, huh? At home, I'm usually a solid US 8 in most companies, and they fit my feet perfectly. So when I splurged on some COS shoes online, I clicked confidently on an EU 38 (UK 5), thinking I had this one in the bag. I mean, the shoes were stunning when they came in—beyond minimalist perfection. But when I tried them on? Disaster. My toes were literally screaming for mercy—they were seriously too tight.

After a little detective work on the COS website, I spotted their size guide and a sneaky little clue: if your feet are slightly wider or your toes are longer (guilty as charged!), they suggest going up half or full size. Lesson learned. I swapped them for an EU 39 (UK 6), and oh, the heavens opened. Pure bliss, total chic—finally, a fit that felt like it was made for me. Moral of the story? Don't snooze on that size chart, friends!

First tip of the day: Don’t blindly pick your usual size. Measure your feet and check COS’s official size chart—or you might end up in the return line. Trust me, a little prep saves a lot of hassle!

Sizing Chart Breakdown: Your Go-To Guide

Speaking of sizing charts, let's get down to business. there is a super detailed sizing chart on the COS website. I've downloaded a handy version to share with you straight from the official COS website, which I've included below for your perusal. It labels the length of the foot and the EU size in centimeters, which saved me from guessing and crossing my fingers and hoping for the best!

COS Sizing Chart

How to Use the Chart

If you measure your foot length (just grab a ruler and trace your foot on paper), you can match it to the chart and pick your size with way more confidence.

Pro tip: If your measurement falls between two sizes, I’d lean toward the larger one, especially for COS’s sleeker styles.

Shoe Design Matters: Sizing Varies Across Styles

Another thing I’ve noticed is that COS women’s shoe sizing can vary depending on the style. I’ve worn their Pointed-Toe Flats and Chunky Loafers, and the fit was like night and day.

Comparing Styles: Flats vs. Sneakers

The pointed-toe flats in EU 39 felt snug and sleek—great for showing off a slim foot shape.  But when I grabbed a pair of Chunky Sneakers in the same size, they felt a bit roomier—probably because the design is more casual and the thicker sole gives more space inside.

My Style-Specific Sizing Advice

Here’s my advice: for slimmer styles like ballet flats, Mary Janes, or anything with a pointed toe, stick to your usual EU size or go up a half size if you’re on the fence.  For looser styles like boots or sneakers, your regular size should do the trick.  Shopping online?  If this is your first time shopping at COS, you should probably order two sizes to try on because the company has a reasonable return policy. Isn't it wiser to be safe than sorry?

Foot Shape Enters the Scene: Wide or Narrow Feet, Be Aware

Beyond the style, your foot shape can totally make or break the fit. I’ve got a friend with wider feet who found COS’s pointed-toe designs to be a total disaster—she sized up to an EU 40 (she’s usually a 39), but still felt pinched and ended up passing on them.

Wide Feet vs. Narrow Feet: The Struggle Is Real

Meanwhile, another friend with slender feet was enamored with COS and said the streamlined fit felt like it was made for her, with no slipping or gaps. So if you have wider, narrower feet, or high arches, I suggest you either try them on in-store or check out the customer reviews to see if they fit.

Pro Tips for Getting the Right Size

To keep you from sizing drama, here are some tricks I’ve picked up across my COS shoe adventures.

Top 4 Tips to Nail the Perfect Fit

1. Take Your Measurements: Don’t skip this! Grab a ruler, measure your foot length and width, and match it to COS’s size chart—they’ve got it down to centimeters.
2. Read Reviews: On COS’s website or platforms like Farfetch and SSENSE, buyers drop gems like “runs small” or “fits wide feet.” Use those as your guide.
3. Ask Customer Service: COS’s online support is legit. Snap a pic of your foot or ask about a specific style—they’ll hook you up with advice.
4. Try Before You Buy: If you can, hit up a COS store (they’ve got spots in big cities like NYC, London, or Shanghai) and try on a few pairs to see what works.

My COS Shoe Experience: Style Meets Comfort

Now let’s talk about actually wearing these stunners! My fave pair is a black leather Mary Jane from COS—got them in EU 39, and they’re a total dream.

Why I Love My COS Mary Janes

These shoes look textured and go just right with an A-line skirt or tailored pants. I also got a pair of white chunky-soled sneakers in the same size, but they felt a little loose. Throw on a thin insole and they're perfect.

A Note for Wide Feet

Bottom line: in the right size, COS shoes are a winner in terms of style and comfort. They’re total closet MVPs, but be cautious if you have wider feet as they don't come in half sizes, so it can be a bit tricky.

Final Verdict: Are COS Shoes True to Size for Women?

So, let’s circle back to the big question: Are COS women’s shoes true to size? My take? Yes, but there’s a catch. They’re not your run-of-the-mill Nike or Adidas with cookie-cutter fits. Put in a little effort—check their size chart, think about your foot shape and the style—and you’ll land the perfect pair, no sweat.
