Merrell is an American brand so we primarily show US sizing. We recommend purchasing your regular US size.
To help you determine your US size, check the size tag under the tongue of your current pair of shoes. Most shoes sold in Australia are from American brands and therefore are likely to show the US size listed together with the equivalent UK and EU sizes.
Handy tip: If your current pair of shoes states the CM/centimetre size, we recommend getting the same CM size equivalent in Merrell's. This is because US, UK and EU sizing can differ between brands, but the length of the innersole will always be the same. You can find the CM sizing on our size guides.
If you have any concerns about fit, feel free to reach out to our Merrell Experts below, who can help you choose the right size.
