How Australian shoe sizing works
Australian sizing has two common conventions. Australian men's sizes generally align with UK men's sizing. Modern Australian women's retail often aligns with US women's sizing, but some heritage brands continue to use a UK-based scale.
Brand sizing disclaimer
Brand, model, width, and intended use can change the fit. Blundstone and R.M. Williams boots use brand-specific Australian or UK-style guidance. Crocs are commonly marked with US unisex sizes. When a product page provides a CM or JP measurement, compare it with your measured foot instead of relying only on EU or AU numbers.
Measure before ordering
Measure both feet at the end of the day while wearing the socks you plan to use. Choose the larger foot, then compare its length in centimeters with the manufacturer's chart. Allow room for natural toe movement, but do not size up solely because a conversion table differs by half a size.
