Australian sizing is not recognised as a standard size by Merrell
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.
