How Ecco Sizing Works

How-Ecco-Sizing-Works

Ecco shoes follow European sizing, which means they use a different system than US sizes. Instead of the familiar US numbering, Ecco sizes increase consistently in whole numbers, and unfortunately, they don’t offer half sizes. But don’t worry—it’s easy to find your equivalent US size using a simple formula:

  • For men, take your US size and add 34. So, if you’re a US 10.5, that gives you 44.5, but since Ecco doesn’t do half sizes, you’d go with a 44.
  • For women, add 31 to your US size. A US 7.5 becomes 38.5, so you’d round down to a 38.

Easy, right?

But what if you’re stuck between sizes? That’s where Ecco’s clever design comes in—the Extra Width Insole

Just like Ecco, RM Williams sizing can be a bit tricky to nail down—check out our guide here to make sense of it all.

Extra Width Insole:

If your shoe feels too snug, simply remove this insole, and you’ll gain a little extra room.

Now, here’s the cool part: most shoes, when you take out the insole, leave you staring at cork or plastic—not exactly cozy. But with Ecco shoes, even when you take the insole out, the interior is fully finished, so you won’t feel like you’re walking on an exposed surface. Removing the insole doesn’t just add width; it also lowers your foot slightly, giving you extra volume inside the shoe.

For example, if a 43 is just a bit too tight and a 44 feels too loose, taking out the insole from the 43 can give you that perfect in-between fit. This small adjustment can make a big difference, especially if you’re someone who typically falls between sizes.

And here’s something you might not know: Bogs boots use a similar approach with their Flex Width Insole. If your Bogs feel a little tight, just pop out the extra insole, and you’ve got instant extra room. Check out the full Bogs sizing article for more details.

Now, one of the standout features of Ecco shoes is their Freedom Fit design…

Freedom Fit:

Unlike many brands that offer different widths, instead of offering different widths, Ecco design their shoes to be snug in the heel and midfoot but roomy in the toe box. So, whether you have a narrow foot or a wide forefoot, this means your heel stays locked in place, while your toes have plenty of space to breathe and splay naturally as you walk.

Leather:

Ecco also uses high-quality leather and well-designed lacing systems, which allow some flexibility in fit. If your shoes feel slightly snug at first, they’ll often mold to your feet over time. This adaptability makes it easier to get the right fit, even without half sizes.

How Ecco Biom H4 & Biom Hybrid 4 GTX Fit

how-ecco-biom-h4-fits

The Ecco Biom H4 fits true to size, which offers a secure fit while still giving your toes plenty of space to sit comfortably. Compared to older Ecco golf shoes, the H4 provides a more locked-in feel without feeling restrictive.

If you have wider feet, you can easily adjust the fit by removing the insole. Inside, you’ll see it labeled Extra Wide, which means taking out the insole will instantly create more space without needing to size up.

The Biom Hybrid 4 GTX, on the other hand, runs large—at least half a size bigger than your normal size. If you typically wear a 10, you’ll likely need a 9.5, and in some cases, even a 9 might be a better fit. Since these shoes are on the roomier side, it’s best to start with a smaller size to avoid excess movement inside the shoe.

How the Ecco S3 Fits

The Ecco S3 has a more traditional shape and looks a bit narrower compared to models like the LT1 and C4. It still has some room in the forefoot, but overall, it’s a slightly slimmer fit.

If you’re used to shoes built on Ecco’s Biom last, which is shaped based on thousands of laser-scanned feet, you’ll notice a difference.

Shoes built on the Biom last, like the H4, tend to feel a little wider, especially in the forefoot. But the S3 sticks to a more straight-down-the-line shape, which makes it feel a bit more structured and traditional.

If you like a snugger fit but still want some space for your toes, the S3 could be a good option. It doesn’t have the same extra-wide feel as some of the Biom models, but it still offers a comfortable fit without feeling overly tight.

How the Ecco MX Mid GTX Fits

how-ecco-mx-mid-gts-fits

The Ecco MX Mid GTX runs a little big. Normally, when it comes to boots, I’d recommend going up half a size to make sure your toes have some extra space in the front.

But with the MX Mid, if you size up, you’ll end up with too much room, which can affect the fit and feel of the shoe. Instead, I’d suggest starting half a size smaller than your usual size. In some cases, you might even need to go down a full size to get the right fit.

How Ecco Vitrus II Chelsea Boots Fit

how-vitrus-ii-chelsea-boot-fits

If you want to get the Ecco Vitrus II Chelsea boots, these boots are a fan favorite for their sleek look and comfy fit. But I’d really recommend trying them on in-store if you can. Why? Because Ecco’s sizing can vary depending on the style and last, and the Vitrus II is no exception.

But if you’re getting them onlin, if you’re a European 41.5 on the Brannock device, you could comfortably wear anything from a 41 to a 42 in Ecco. But if you go down to a 41 for a snugger fit, the length might feel a bit too short, especially in the waist area.

How Ecco BIOM 2.1 X Country Fit

how-biom-2.1-x-country-fits

Here’s the good news: they run true to size, so you can stick with your usual size without much guesswork.

That said, they do feel a little roomy in the toe box, which is great for letting your toes splay naturally as you run. But keep in mind, the midfoot area is slightly narrow, so if you’ve got wider feet, you might feel a bit of a squeeze there.

My advice? Don’t size down—these shoes are designed to fit snug but not tight, and sizing down could make the midfoot feel too restrictive.

How Ecco Soft 7 Fit

how-ecco-soft-7-fits

If you’re a US 10, for example, you’d normally go with a European 44. But with the Soft 7s, I’d recommend sizing down to a 43. Why? Because the extra room can make them feel a bit loose if you stick to your usual size.

That said, the Soft 7s are designed to be snug in the heel and midfoot while giving your toes plenty of space to breathe. So, if you’re between sizes or worried about them feeling too tight, remember Ecco’s Extra Width Insole trick—removing it can give you a bit more room without going up a full size.

How Ecco Citytray Dress Shoes Fit

how-citytray-fits

The Citytray runs a bit oversized.

The Citytray is just as cozy as any other dress shoe, but at times, it feels like your feet are swimming in them. If you’re someone who likes a snug fit, I’d recommend going half a size or even a full size down from your usual size.

For example, if you’re a US 10, try a European 43 instead of the usual 44. This should give you a better fit without sacrificing the comfort Ecco is known for.

Nown let’s take a walk through the history of Ecco—a brand that’s been quietly crushing it in the footwear game for decades.

Alright, let’s get down to the nitty-gritty of measuring your feet because when it comes to Ecco shoes, getting the right size is non-negotiable…

How to Measure Your Feet

The Best Method:

Let’s get one thing straight—the absolute best way to know if an Ecco shoe fits is to go into a store and try them on. Seriously, there’s no substitute for slipping your foot into a shoe and feeling it for yourself.

Ecco’s retail staff are trained to help you find the perfect fit, and they’ve got all the tools (like the Brannock Device) to make sure you walk out with shoes that feel like they were made just for you. Trust me, it’s worth the trip.

The Brannock Device:

measure-your-feet-with-a-brannock-device

If you’ve ever been to a shoe store, you’ve probably seen the Brannock Device—that metal contraption that looks like a cross between a ruler and a torture device (don’t worry, it’s not). This thing is the holy grail of foot measurement, and here’s how it works:

  • Step 1: Stand Up

Always measure your feet while standing. Your feet expand under your weight, so this gives you the most accurate measurement.

  • Step 2: Heel to Toe

Place your heel firmly against the back of the device. Slide the slider forward until it touches your longest toe (which, fun fact, isn’t always your big toe—some people have a longer second toe).

  • Step 3: Width Measurement

The Brannock Device also measures width. Slide the width bar snugly against the widest part of your foot. This is crucial because a shoe that’s too narrow or too wide can ruin the fit, no matter how perfect the length is.

  • Step 4: Record Your Size

The device will give you your exact length and width measurements. Write these down and go back to the Ecco size chart and see how you can convert your measurments to the EU sizing system.

The Home Method:

how-to-measure-foot-length-and-width-infographic

Can’t make it to a store? No problem. You can measure your feet at home with just a piece of paper, a pen, and a ruler.

Here’s how:

  • Gather Your Supplies

Grab a blank piece of paper, a pen or pencil, and a ruler or measuring tape.

  • Trace Your Foot

Place the paper on a hard, flat surface (no carpet!). Stand on the paper and trace the outline of your foot. Keep the pen perpendicular to the paper to avoid skewing the measurement.

  • Measure Length and Width

Use the ruler to measure the distance from the heel to the longest toe (length) and across the widest part of your foot (width).

Again, once you have your measurements, compare them to the size chart. Keep in mind that sizes can vary between brands, so always go by measurements, not the number on the box.

Alright, now that you’ve got your measurements, let’s talk about what to look for when trying on shoes. Because even with the perfect size, there are a few things that can make or break the fit:

Things to Keep in Mind When Trying Shoes

The Wiggle Room Test

Your toes should have a little wiggle room—about a thumb’s width between your longest toe and the end of the shoe. Too tight, and you’re asking for blisters. Too loose, and your foot will slide around.

The Width Check

The shoe should feel snug but not tight across the widest part of your foot. If it’s pinching or bulging, it’s not the right width.

Walk It Out

Don’t just stand there—take a lap around the store. Pay attention to how the shoe feels as you walk. Are there any pressure points? Does your heel slip? These are red flags.

Consider the Sock Factor

If you’re planning to wear socks with the shoes, bring a pair to try them on with. Thick socks can make a big difference in fit.

Time of Day Matters

Your feet swell throughout the day, so it’s best to try on shoes in the afternoon or evening when your feet are at their largest.

Trust Your Instincts

At the end of the day, you know your feet better than anyone. If something feels off, it probably is. Don’t settle for “good enough”.

Ecco Sizing FAQ

Do Ecco shoes run true to size?

It depends on the model. For example, the Ecco Biom H4 and BIOM 2.1 X Country running shoes run true to size, while the Biom Hybrid 4 GTX and MX Mid GTX tend to run larger. The Soft 7s and Citytray dress shoes, on the other hand, often feel roomy.

How do I convert my US shoe size to Ecco’s European sizing?

For men, add 34 to your US size. For example, a US 10.5 becomes a European 44.5, but since Ecco doesn’t offer half sizes, you’d round down to a 44. For women, add 31 to your US size. A US 7.5 becomes a European 38.5, so you’d round down to a 38. This simple formula ensures you get the closest fit possible.

What should I do if I’m between sizes in Ecco shoes?

If a shoe feels slightly tight, removing the insole adds extra width and lowers your foot slightly, creating more room. For example, if a 43 feels snug and a 44 is too loose, removing the insole from the 43 can give you the perfect in-between fit.

Wrap Up

There you have it. Shoe shopping can be a pain. Sizes are all over the place, and half the time, you’re left wondering if you’re a 43 or a 44. But with Ecco, it’s not as complicated as it seems. You’ve got the Ecco size charts, the tips for measuring your feet, and those little hacks like the Extra Width Insole to help you out.

The truth is, Ecco shoes are designed to work with you, not against you. They’re not trying to squeeze your feet into some weird, one-size-fits-all mold. Instead, they give you room to breathe (literally, in the toe box) while keeping things snug where it matters.

So, what’s your experience with Ecco sizing?

Did you size up, size down, or stick to your usual number? Or, did it take a little trial and error? Maybe you’ve got a favorite pair of Soft 7s that feel like walking on clouds, or perhaps you’ve got some thoughts on how the Biom Hybrid 4 GTX runs a bit big. Whatever it is, we want to hear about it.
