Shoe Size 37 in US Women: International Shopper Quick Guide
If you’ve ever tried buying shoes from another country, especially from Europe, you’ve probably come across sizes like 36, 37, 38 — and wondered how they compare to U.S. sizes. One of the most common questions among women is, “What is shoe size 37 in US women’s sizing?” In this blog, we will break down everything you need to know about size 37 in US women’s shoes.
Whether you’re shopping online, trying on shoes abroad, or just confused by the numbers, this guide will help you understand and feel confident in choosing the right shoe size.
What Is Shoe Size 37 in US Women’s Sizing?
Shoe size 37 is a common European (EU) size that many international brands use. In the United States, women’s shoe sizes are labeled differently, so conversion is necessary when shopping globally.
Typically, EU size 37 is equal to US women’s size 6.5 or 7, depending on the brand and fit. This difference exists because shoe sizing systems are not standardized across regions. European sizing is based on the length of the shoe last in centimeters, while US sizing is measured in inches, using a different sizing formula.
In most cases:
- If you wear a size 6.5 US, a 37 EU will fit you quite well.
- In some brands, if the shoes run small, a US 7 might also match size 37.
It’s important to always check the brand’s size chart before making a purchase. Slight differences in manufacturing can cause fit variations even when the size number appears the same.
Is Size 37 a US 6.5 or 7? Breaking Down the Fit
This is a tricky but important question. Size 37 in EU is not always an exact match to just one US size. It usually sits between US 6.5 and 7. The difference is often small, but it matters when you’re shopping online and can’t try the shoe on.
Here’s why the fit varies:
- Brand differences: Some brands run narrow, wide, small, or large. For example, Italian leather shoes might fit more snugly than American sneakers.
- Shoe type: Boots and sneakers might give more room than heels or sandals.
- Material: Leather shoes stretch more over time, while synthetic ones may not.
Many women find that size 37 feels more like a 6.5 US in sandals or heels, and closer to US 7 in sneakers or boots. Always read product reviews or sizing advice when buying unfamiliar brands.
Women’s Shoe Size Conversion Chart (EU to US)
To make shoe shopping easier, here’s a helpful conversion chart that compares EU and US women’s sizes.
| EU Size | US Size (Women) | UK Size |
|---|---|---|
| 35 | 5 | 2.5 |
| 36 | 6 | 3.5 |
| 37 | 6.5 – 7 | 4 – 4.5 |
| 38 | 7.5 – 8 | 5 – 5.5 |
| 39 | 8.5 | 6 |
| 40 | 9 – 9.5 | 6.5 – 7 |
Keep in mind: half sizes may not always be available in all countries or brands. When you’re unsure, round up rather than down to avoid a tight fit.
Does EU Size 37 Fit True to US Sizes? What You Need to Know
Many women ask if size 37 fits just like its US equivalent. The answer is — not always.
Fit can change depending on:
- Brand origin: European shoes tend to run narrower, especially in dress shoes.
- Shoe design: Loafers, ballet flats, and pumps may feel tighter in the toe area.
- Socks or foot liners: Wearing thicker socks can make a tight shoe feel even smaller.
If you’re used to American brands like Nike, New Balance, or Skechers, a size 6.5 or 7 will likely feel familiar. But when you switch to brands like Zara, Mango, or European boutique brands, you might feel a tighter fit even if you pick size 37.
Pro Tip: If you’re between sizes, or if the product reviews say the shoe “runs small,” consider going up half a size.
How to Measure Your Foot to Match EU Size 37 in the US
You don’t need fancy tools to measure your foot at home. All you need is a piece of paper, a ruler, and a pen. Measuring your foot properly can help you match your correct EU or US shoe size, including size 37.
Follow these steps:
- Place a piece of paper flat on the floor, touching the wall.
- Stand on the paper with your heel against the wall.
- Mark the tip of your longest toe on the paper.
- Measure the distance from the edge of the paper to the toe mark in centimeters.
- Use a conversion chart to find your EU size based on that length.
Foot Length to EU Size Estimate:
- 22.5 cm = EU 35
- 23 cm = EU 36
- 23.5 cm = EU 37
- 24 cm = EU 38
Your foot length should be around 23.5 cm if you’re a perfect fit for size 37. Remember to measure both feet, as one might be slightly longer.

Common Mistakes When Converting EU to US Shoe Sizes
Avoid these common errors when dealing with EU to US shoe sizes:
- Assuming one size fits all brands. Each brand has its own sizing quirks.
- Ignoring half sizes. Size 37 usually falls between US 6.5 and 7, not just one or the other.

Size 37 in Women’s Sneakers, Heels, and Boots: Is It the Same?
Different types of shoes can feel different even if the size is the same. Here’s a simple table to show how size 37 varies across shoe types.
| Shoe Type | Size 37 Fit in US Women |
|---|---|
| Sneakers | US 7 – More relaxed fit |
| Heels | US 6.5 – Snug, sometimes tight |
| Boots | US 6.5 or 7 – Depends on thickness of socks |
| Flats | US 6.5 – Tighter in the toe box |
When shopping for heels or pointed-toe shoes, size 37 might feel tighter, so sizing up to a US 7 could be more comfortable.

FAQs
1. What is EU shoe size 37 in US women’s sizing?

2. Does EU 37 always fit like US 6.5?

4. Is there a difference in fit between sneakers and heels in size 37?

5. How do I know if size 37 is right for me?
Measure your foot from heel to toe. If it’s about 23.5 centimeters, EU size 37 is likely the best fit. You should also compare this measurement to the brand’s size chart before purchasing.
6. What if I’m between US sizes 6.5 and 7?
If you’re between sizes, EU 37 might work depending on the shoe type. Choose 37 for a snug fit or 38 for more room, especially if wearing socks or you prefer a looser feel.
7. Are European shoes narrower than US shoes?
Yes, many European brands tend to have a narrower fit, especially in dress shoes or leather styles. If you have wide feet, you may need to size up or choose styles with a wider width option.

No. Different brands may have slight differences in how they convert sizes. Always consult the brand’s official size chart, as some brands may label size 37 as either US 6.5 or US 7.
9. Can I return shoes if size 37 doesn’t fit?
Return policies vary by store and country. Most online retailers allow returns, but you should check the return policy before purchasing, especially for international or discounted items, to avoid restocking fees or shipping charges.
10. Should I size up in winter boots if I wear EU 37?
Yes, if you plan to wear thick socks or thermal insoles, it’s smart to size up to EU 38 for added comfort. Winter boots can feel tighter due to insulation, so going up half a size is common.
