How to use the shoe size chart?
For example, if you wear EU 42, you will find UK 8, US 9.5 for women, or US 9 for men in the same row of the table.
For US shoe sizes, the distinction between women and men is particularly important, as different sizing scales are used.
If you want to convert a known shoe size directly, you can also use our [shoe size converter] for this purpose.
Why can the actual size still vary?
Shoe size primarily describes length. However, for the actual fit, shoe width, last shape, toe box space, and the material and construction of the shoe also play a role.
Therefore, a shoe can be the correct length and still feel too tight or too wide. More information can be found under [Shoe widths at Sioux] and [Shoe size & fit].
Measure shoe size or learn more about conversion?
If you are not sure of your shoe size, you can first determine your foot length. We explain how to do this step-by-step under [Determine your shoe size yourself].
