When it comes to buying shoes internationally, one of the most common challenges shoppers face is figuring out the differences in shoe sizes. For those buying shoes from Australia, understanding the AU shoe size to US conversion is essential. With different sizing systems used across countries, it can be confusing to figure out which size will fit best. In this guide, we’ll break down everything you need to know about converting Australian shoe sizes to US sizes, along with other important shoe size conversions you might encounter when shopping for shoes or clothes internationally.
The Importance of Correct Shoe Sizing
Getting the right shoe size is critical not only for comfort but also for preventing foot problems. Wearing shoes that don’t fit well can lead to blisters, bunions, or other uncomfortable conditions. This is why understanding the AU shoe size to US conversion, as well as other international sizing systems, is so important, especially when you’re shopping online.
Whether you’re buying shoes from an iconic Australian brand, or perhaps you’re shopping from a retailer that ships globally, it’s essential to know how AU shoe sizes compare to US sizes. After all, a shoe that fits perfectly in one country may not be the same in another.
AU Shoe Size to US Conversion: What You Need to Know
Australia uses a unique shoe sizing system that differs from the US, UK, and European systems. While it’s similar to the UK shoe size system, there are some key differences that shoppers need to understand. Below, we’ll explore how to convert AU shoe sizes to US sizes for both men and women.
AU Shoe Size to US Women’s Conversion
For women, the AU shoe size to US conversion is relatively straightforward, but it does vary slightly depending on the brand and shoe style. Here’s a basic guide for converting AU shoe sizes to US women’s sizes:

- AU 4 = US 6
- AU 5 = US 7
- AU 6 = US 8
- AU 7 = US 9
- AU 8 = US 10
- AU 9 = US 11
- AU 10 = US 12
If you’re used to shopping for EU shoe size to US, you’ll notice that the conversion charts for both women’s and men’s shoes are quite different. While US size to EU shoes or EU size to AU clothes can be complicated, AU to US women’s shoes tend to follow a pretty predictable pattern.
AU Shoe Size to US Men’s Conversion
For men, the conversion between AU and US sizes is also quite simple, but with a slight difference from the women’s chart. Here’s the basic conversion for AU to US men’s shoe sizes:

Australian Shoe Size Conversion: Other Important Comparisons
When shopping for shoes, it’s not just about AU shoe size to US—there are other important conversions to keep in mind. If you’re looking to understand how Australian sizes compare to other international systems, here’s what you need to know:
Australian Shoe Size to EU
If you’ve ever found yourself asking, “How does the Australian shoe size compare to European sizes?” you’re not alone. The Australian shoe size system aligns closely with the UK system, but there are slight differences that make it important to have a good chart on hand.
For instance:
- AU 4 = EU 37
- AU 5 = EU 38
- AU 6 = EU 39
- AU 7 = EU 40
- AU 8 = EU 41
- AU 9 = EU 42
- AU 10 = EU 43
This is useful when you’re browsing shoes from European brands, especially if you’re looking for Euro shoe size to US women’s conversions or need to figure out the US size to EU shoes for men.
UK Shoe Size to US
Another conversion that can be helpful when dealing with international shoe shopping is the UK to US shoe size. Since Australian sizes are more closely related to UK sizes, understanding this conversion can also help you with AU to US shoe size conversions. Here’s a brief comparison:
- UK 4 = US 6
- UK 5 = US 7
- UK 6 = US 8
- UK 7 = US 9
- UK 8 = US 10
- UK 9 = US 11
- UK 10 = US 12
If you’re looking at shoes from iconic UK brands, these conversions will help you determine the correct size in the US.
How to Use a Shoe Size Chart for International Shopping
When you’re shopping for shoes internationally, it’s always helpful to refer to a shoe size chart that includes all the major sizing systems. Here’s how you can make use of the chart:
Find Your AU Size: Start with your Australian shoe size.
Convert to US Size: Use the conversion guidelines above to convert to your US shoe size.
Check for Fit: Remember, different brands may have slightly different sizing standards, so it’s always a good idea to check the brand’s specific size chart before making a purchase.
Look at Reviews: If you’re still unsure, check customer reviews for feedback on sizing.
Many websites also offer a shoe size converter tool that helps you quickly convert between AU shoe size to US, EU, or UK sizes.
Common Issues with Shoe Size Conversions
Even with a good conversion chart, shoe sizing can sometimes be tricky, especially when the shoes come from countries with different sizing systems. Here are a few issues you might encounter:
Different Sizing Systems for Different Brands: Some Australian brands may follow slightly different sizing standards. This can affect the AU shoe size to US women’s or AU shoe size to US men’s conversion.
Unisex Shoes: For unisex shoes, conversion can be tricky because sizing often varies based on the gender it’s intended for. Be sure to check both the men’s and women’s size charts.
Wide or Narrow Feet: If you have wide or narrow feet, it’s essential to check the shoe’s fit guide before buying. A size 8 in Australia might not fit the same in the US if the shoe is designed for a different foot width.
Other Shoe Size Conversions You Might Need
In addition to the AU shoe size to US conversion, you may also need to convert sizes for clothes and other footwear. Here are some common conversions that might be helpful:
US size to AU clothes: The US and Australian clothing sizes often differ, so it’s good to know the equivalents.
EU size to AU clothes: If you’re buying clothes from European brands, the sizing may be different from the AU system.
Iconic Australian Brands: Many iconic Australian brands like Ugg Australia and Billabong follow AU sizing, so be sure to check the sizing guides when shopping.
Tips for Shopping for Shoes Online
When buying shoes from overseas, particularly from Australia, here are some helpful tips to ensure a smooth shopping experience:
Always Double-Check the Size Chart: Always check the shoe size chart on the retailer’s website. The conversion from AU shoe size to US might vary slightly depending on the brand.
Order From Reputable Retailers: Order from trusted websites that offer easy returns and exchanges, just in case the shoes don’t fit as expected.
Consider Local Sizing: If you’re buying shoes online from an international store, make sure you take your local shoe size and convert it to the appropriate international size.
Look for Customer Reviews: Reading customer reviews can provide insight into how true to size the shoes are and whether they run large or small.
