Merrell is an American based brand, therefore we primarily use US sizing. US sizing is equivalent to AU sizing.
We recommend referring to the US sizes when making a purchase. E.g. A men's AU 9 is the same as a men's US 9.
You can view our full-size guides by clicking on "Size Guide" when viewing the item.
See our full size guides below.
Good to know: Half sizes will affect the length of the shoe, rather than the width. For example a men's US 9 is 0.5cm longer than a US 8.5. The width will increase slightly, in proportion to the length.
Please note that these are guides only. The cm length is the length of the innersole, we advise allowing an extra 1cm for when calculating your size.
