Sizing conventions vary by brand and by cut — this table shows the standard published conversion. Always check the garment's own size chart when one is available. See how these tables are compiled.
Flip it around and an AU 11 is a US 11 — Australian and American men's shoe numbering track each other closely enough that this is one of the simpler regional conversions this site covers.
Where it breaks is a brand that sources its lasts from a British supplier rather than an American one: the AU size on the box can then follow UK convention instead, landing a full size away from what a straight AU-to-US read would suggest, so cross-checking foot length against that specific brand's own chart matters for an unfamiliar label.
Frequently asked questions
Why would an AU 11 not convert cleanly to a US 11?
Some Australian brands build on a UK-derived last rather than a US one, so their printed AU number can quietly follow British sizing instead — worth a foot-length check on a brand you have not ordered from before.
