Frequently asked questions
Why does my size vary between brands?+
Sizing charts differ by brand and even by model — most run within half a size of these standard conversions. When in doubt, go by foot length in centimetres.
How do I measure my foot length?+
Stand on a sheet of paper, mark your heel and longest toe, and measure the distance in centimetres. Compare it with the JP/cm value shown here.
