Navigating international shoe sizes can be confusing, especially when you’re trying to convert European sizes to US sizes. If you’ve ever wondered “What is size 40 Euro in US shoe size?”, you’re not alone. Understanding shoe size conversions is crucial for online shopping, buying gifts, or simply ensuring the perfect fit, no matter where you are in the world. This guide will clearly explain how to convert Euro size 40 to US shoe sizes for both men and women, and provide comprehensive shoe size charts for your reference.
Understanding Euro Shoe Sizes
The European shoe sizing system is widely used across Europe and many other parts of the world. Unlike the US system, which uses a different scale and sometimes gender-specific measurements, the Euro system is generally considered unisex, although conversions to US sizes can differ for men and women. Knowing your Euro size is a great starting point, but converting it accurately to US sizes is essential for those in the United States.
Converting Euro Size 40 to US Shoe Size
Size 40 Euro is a common shoe size, but its US equivalent differs slightly between men’s and women’s shoes. Here’s a breakdown to clarify:
Size 40 Euro to US for Women
For women’s shoes, a Euro size 40 typically converts to a US size 9.5. If you are a woman and usually wear a Euro size 40, you’ll likely need a US size 9.5 for a comparable fit.
Size 40 Euro to US for Men
For men’s shoes, a Euro size 40 is equivalent to a US size 7. Men who wear a Euro size 40 should look for a US size 7 when purchasing shoes in the US sizing system.
It’s important to remember these are general conversions. Different brands and shoe types can sometimes vary slightly. Always check the specific brand’s size chart when available.

How to Measure Your Shoe Size Accurately
While conversion charts are helpful, measuring your foot is the best way to ensure accuracy. Here’s how to measure your shoe size at home:
- Step on a ruler: Place a piece of paper on the floor and stand with your heel against a wall. Place a ruler or measuring tape on the paper, aligned with your heel.
- Mark the longest point: Measure from your heel to the tip of your longest toe. Make sure to measure both feet, as one may be slightly larger than the other. Use the measurement of the larger foot when determining your shoe size.
- Use the charts: Compare your measurement in inches or centimeters to the charts above to find your US and Euro size.
Keep in mind that foot measurements are just a starting point. Shoe style and brand can also affect fit.
Tips for Perfect Shoe Fit
- Size Up When in Doubt: If you are between sizes, especially for athletic shoes or hiking boots, it’s generally recommended to size up. This provides more room for comfort and prevents issues like blisters or lost toenails, particularly during activities where your feet may swell.
- Half Sizes Matter: A half size can make a significant difference in shoe fit. Shoes that are even half a size too small can lead to discomfort and foot problems.
- Account for Foot Size Variation: It’s very common for one foot to be slightly larger than the other. Always fit shoes to your larger foot.
- Consider Shoe Tightness and Looseness: Shoes should be snug but not too tight or too loose. You should be able to fit a thumb’s width between your longest toe and the end of the shoe. You should also be able to fit an index finger snugly between your heel and the back of the shoe.
- Try Shoes on at the End of the Day: Your feet naturally swell throughout the day, especially if you are active. Trying on shoes in the late afternoon or evening will give you a more accurate idea of how they will fit when your feet are at their largest.
