PLEASE SELECT US SIZING. US 9 = AU 8 (on pull tags). For your reference, since the boots are Australian-made, they will have the AU sizing on them, which is one size less than the US size. We are selling based on the US size. US 9 is the same as 8 AU. So, if you order the boot with size 9 US, the tag on the boot will say 8 (Australian size) on the pull strap.
