US to Aus Shoe Size Conversion: For Men, Women & Kids

If you’ve ever stared at a pair of shoes from an American brand and wondered whether they’ll fit you in Australia, you’re not alone. Converting shoe sizes between the US and Australia is straightforward once you know the key rule: women’s sizes match, men’s differ by one; this guide covers exact conversions with charts and a measuring method.

Women’s US = Aus Same numeric size · Men’s Aus = UK Same numeric size · Men’s US vs Aus US is +1 (e.g., US 10 → Aus 9) · EU 38 to US women’s 7.5 · CN 39 to US women’s 8

The core conversion rules are summarized in the table below.

Does Aus use UK or US sizes?

The short answer: it depends on who you’re buying for. Australian women’s sizing follows the US scale, while men’s sizing follows the UK scale. That split is the single most important thing to know when converting.

Women’s sizing: Australia uses US sizes

• A women’s US size 7 is the same as an Australian women’s size 7. Entire Podiatry (podiatry footwear specialists) confirms this parity.
• Ashbree’s conversion chart lists ladies AU size 8 as equivalent to UK 6 and EU 39, reinforcing the US-to-AU alignment for women (Ashbree Saddlery, tack & footwear retailer).

Men’s sizing: Australia uses UK sizes

• Australian men’s shoe sizes are numerically identical to UK sizes. Entire Podiatry states this directly.
• A US men’s size 10 converts to Australian men’s 9 (because Aus = UK, and UK 9 = US 10). BullFiNews (consumer comparison site) provides the same rule.

Children’s sizing: A different standard

• Children’s sizes in Australia often follow UK/European scales, but vary by brand. No uniform conversion exists.

The pattern: always check the gender-specific rule before ordering.

What is a US size 7 shoe in Australia?

Because the answer flips by gender, we’ll take each case separately — then give you a full conversion table for common sizes.

US women’s size 7 to Australia

• A US women’s size 7 is an Australian women’s size 7. Ashbree Saddlery (tack & footwear retailer) and Entire Podiatry (podiatry footwear specialists) both confirm this.

US men’s size 7 to Australia

• A US men’s size 7 is an Australian men’s size 6. Since Aus men’s = UK men’s, and UK 6 = US 7, the conversion is straightforward. BullFiNews (consumer comparison site) illustrates this pattern.

Conversion table for common US sizes

Six common US sizes, one pattern: women’s stay the same across US and Aus, men’s drop by one when crossing the Pacific.

The pattern: if you’re a woman buying US-brand shoes in Australia, buy your usual number. If you’re a man, go down one size. Shoe Me (Australian footwear retailer) adds that this rule works for most closed-toe shoes, but always check brand-specific charts.

The takeaway: use the gender rule to avoid sizing mistakes.

Is a 38 a size 7 or 8?

EU size 38 is one of the most commonly asked-about sizes in cross-border shopping. Its US/Aus equivalent depends on gender and the reference system.

EU size 38 in women’s US and Australian sizing

• EU 38 typically corresponds to US women’s 7.5 and Australian women’s 7.5. Ashbree Saddlery (tack & footwear retailer) maps ladies AU 8 to UK 6 and EU 39, placing EU 38 at AU 7.5.

EU size 38 in men’s US and Australian sizing

• In men’s, EU 38 is roughly US 6 and Australian 5.5. Brooks Running Australia Support (official brand size resource) lists US Men 6 as Europe Unisex 38.5, so EU 38 is about US 5.5–6.

CN size 39 and other international conversions

• CN size 39 is approximately US women’s 8 / Australian women’s 8, or US men’s 6.5 / Australian men’s 6. The Purple Store (international size conversion resource) provides CN-to-US mappings that support this.
• UK size 8 is US size 9 (men’s) and US size 8.5 (women’s), again highlighting the gender difference.

The lesson: when in doubt, rely on EU sizing and cross-reference with brand charts.

Comparison: US vs Australian sizing across brands

Three major brands, one fact: even when the rule holds, brand-specific charts can shift boundaries. Here’s how Brooks, Ashbree, and Shoe Me handle the conversion.

The pattern: each brand may vary, so always consult their chart.

How to find your US to Australian shoe size in 4 steps

Charts are convenient, but your foot doesn’t read them. Here’s a practical method to get your size without guesswork.

1. Measure your foot length – Place a piece of paper against a wall, stand on it with your heel touching the wall, and mark the longest toe. Measure the distance in centimetres.
2. Find your EU size – Most sizing systems are built on foot length. Use the EU column in a conversion chart (e.g., 25 cm ≈ EU 39–40).
3. Convert to US/Aus by gender – For women, use the EU-to-US/Aus table above. For men, convert EU to UK first, then subtract 1 for US.
4. Check the brand’s own chart – Shoe Me (Australian footwear retailer) emphasises that fit varies by collection, even within the same brand. Always cross-reference.

The implication: with these steps, you can confidently find your size in any system.

What’s certain and what’s not about US to Aus shoe size

The balance: while core rules are confirmed, brand-specific variations require caution.

Expert perspectives on US to Aus shoe sizing

“Australian women’s shoe sizes are the same as US women’s sizes in the cited guide.”

— Entire Podiatry (podiatry footwear specialists) (source)

“Brooks displays sizing on its Australian site in US sizes only and provides a conversion chart for international sizes.”

— Brooks Running Australia Support (official brand size resource) (source)

“Shoe size conversions are approximate because there is no universal international sizing standard.”

— Shoe Me (Australian footwear retailer) (source)

The implication: these sources agree on the core rules, but each warns that brand-specific charts should be the final authority. Trusting a general chart without cross-checking the brand can lead to a misfit.

Summary

Converting US to Australian shoe sizes comes down to one gender-based distinction: women’s sizes are identical, men’s sizes differ by one. The pattern is supported by multiple retailers and podiatry specialists, but no universal standard exists — brand charts always trump generic tables. For the Australian shopper, the safe move is clear: measure your foot, find your EU length, then apply the gender rule, and always check the brand’s own chart before clicking “buy.”
