UK, US and EU shoe sizes use different sizing systems, so the equivalent size can vary depending on the brand and whether the shoe is men's, women's or unisex.
For the most accurate conversion, check the Size Guide on the product page for the specific shoe you're interested in.
Some brands may also use a different size on the shoe or box. For example, a women's shoe may be labelled with the equivalent men's size. This does not necessarily mean you have received the wrong size.
If you're unsure which size to choose, check the product's Size Guide or contact our Customer Service team with the product name or product code.
