Navigating shoe sizes is tricky enough, but international shoe size conversions can feel like navigating a minefield. What’s a US 8 in the UK? And how does that translate to European sizes?
This guide aims to demystify the world of international shoe sizes, so you can find the perfect fit, no matter where you’re shopping. We’ll break down the different sizing systems, provide easy-to-use conversion charts, and offer tips for measuring your feet accurately and successfully shopping online.
Understanding different shoe size systems
If you’ve ever tried to buy shoes online from a retailer in another country, you may have run into some confusion about shoe sizes. Here’s a quick primer on the most common shoe sizing systems.
Common sizing systems
- US system: Used widely in the United States. Note that men’s and women’s sizes are different.
- UK system: Used in the United Kingdom. UK sizes tend to be smaller than US sizes.
- EU system: Used in Europe. EU sizing is unisex and measured in Paris Points, where each Paris Point equals two-thirds of a centimeter.
- Asian systems: Varies by country. Japan, for example, uses centimeter measurements.
Key differences and considerations
Keep these points in mind as you try to convert your shoe size from one system to another:
- Men’s shoe sizes are often larger than women’s sizes in some systems, such as the US system.
- Shoe sizes can vary quite a bit from shoe to shoe, even within the same brand.
- Two-dimensional measuring tools can only approximate your true shoe size.
Converting Women’s Shoe Sizes
If you’re a woman shopping for shoes online, you may encounter sizes from different countries. Here are a few things to keep in mind as you convert sizes:
- US to EU: A US women’s size 8 is roughly a European size 38 or 39.
- US to UK: Check a conversion chart for the specific size, but in general, you can subtract 2 from your US size to find your UK size.
- US to Asian: Asian shoe sizes are often based on the length of your foot in centimeters.
Here are a few other important considerations:
- Shoe size conversion is an estimate, not a promise.
- Width can also vary between men’s and women’s shoes, so if you have a wide foot, for example, you may need to go up a half size.
- Wear the type of socks or stockings you’d normally wear with the shoes when you’re measuring.
- If you’re a woman buying men’s shoes, a women’s size 9 will be around a men’s size 7.
Converting Men’s Shoe Sizes
Here are some common conversions for men’s shoe sizes:
- US to EU: A men’s size 10 in the US is roughly a size 43 in Europe.
- US to UK: Generally, a UK men’s size is one size smaller than the US size. So if you’re a 10 in the US, you’d likely be a 9 in the UK.
- US to Asian: In Asia, shoe sizes are often based on the length of your foot, measured in centimeters.
Important Considerations
Keep in mind that shoe size conversions are estimates. They aren’t always exact.
Also, remember that shoe width can vary (narrow, medium, wide), and this can affect the fit.
When you’re measuring for shoe size, wear the kind of socks or stockings you’d normally wear with the shoes.
Finally, to convert from women’s to men’s sizes, remember that a men’s shoe size of 7 is equivalent to a women’s size 9.
Converting Between Men’s and Women’s Sizes (US)
As a general rule, if you’re trying to convert to a women’s size, add two sizes to the equivalent men’s size. Conversely, subtract two sizes when converting from women’s to men’s.
For example, a US men’s size 9 is roughly equivalent to a US women’s size 11.
Keep in mind that these conversions are guidelines, and there can be slight variations between brands.
How to measure your feet for the right fit
Getting the right shoe size starts with measuring your feet accurately. Here’s how to do it:
- Measure both feet. Most people have one foot that’s slightly larger than the other. Use the larger measurement to determine your shoe size.
- Measure later in the day. Your feet tend to swell as the day goes on, so measuring in the afternoon or evening will give you a more accurate size.
- Get the right foot length. Make sure you’re measuring the length of your foot from the heel to the longest toe.
- Consider foot width. If you know you have wide or narrow feet, look for shoes that are specifically designed for your foot shape.
- Think about instep height. The height of your instep (the arch on the top of your foot) can affect how a shoe fits.
- Wear socks. When you try on shoes, wear the type of socks you plan to wear with them.
Tips for Online Shoe Shopping
Buying shoes online can be tricky, especially when you’re trying to figure out international sizing. Here are a few tips to help you get it right:
- Check the return policy: Before you buy, make sure you understand the retailer’s return policy.
- Consider the width: Shoe width matters! Pay attention to options like AA, B, C/D, and E.
- Read reviews: See what other customers say about sizing. Do the shoes run true to size, or should you order up or down?
- Think about materials: Leather stretches, while synthetics don’t. Consider materials, construction, and embellishments.
- Use size charts: When available, use brand-specific sizing charts.
Frequently Asked Questions
What are international shoe sizes?
International shoe sizes refer to the various sizing systems used around the world, including US, UK, European (EU), and Japanese systems. These systems often differ, leading to confusion when purchasing shoes from different countries. Conversion charts help to find the equivalent size in your preferred system.
What size is 42 in shoes?
A European shoe size of 42 generally corresponds to a US men’s size of 8.5 or 9, and a US women’s size of 10.5 or 11. However, it’s important to consult a specific brand’s size chart, as slight variations can occur.
What size is 43 in the US?
A European shoe size 43 typically translates to a US men’s size 9.5 or 10. For women, a EU size 43 is roughly equivalent to a US size of 11.5 or 12. Again, always double-check a brand’s size guide for the most accurate conversion.
What size is 40 in US size?
A European shoe size 40 is usually equivalent to a US men’s size 7 or 7.5, and a US women’s size 9 or 9.5. Keep in mind these are approximate conversions, and it’s best to refer to the specific brand’s sizing chart for the most precise fit.
To Conclude
Getting the right shoe size is easier when you understand international sizing systems and take accurate measurements.
Keep in mind that shoe sizes can vary by brand, so check the size charts and reviews before you buy.
When in doubt, choose a shoe size that’s a little too big rather than a little too small. You can always add an insole or wear thicker socks.
