Australian sizing is not recognised as a standard size by any of the brands that we stock.
The closest sizing to Australian we advise is US. For conversions we recommend checking your current shoes and seeing if there is a displayed size in US, UK or EU.
Sizing does vary between brands and even different styles in the same brand. The size guide is a recommendation to assist is choosing the best size for you but as every foot is different you may not know for sure until you try a size on.
We offer free returns via post, or in store so you can feel comfortable purchasing online and getting the opportunity to try the shoes on.
