Frequently asked questions
Why do brands differ by half a size?
Last shapes and manufacturing vary. The table gives the standard conversion; individual brands may run small or large, so always check the brand's own chart when ordering online.
How do I measure my feet?
Stand on a sheet of paper at the end of the day, trace both feet, and measure heel to longest toe in centimeters. Use the larger foot.
