Japanese/CM - These measurements are in centimeters.
Unfortunately, there is no international sizing standard. Sizes vary from country to country. Please use the tables above only as a guide to help you in ordering the correct size. For our Australian customers, please note that the Australian size is equal to the standard U.S. Men's or Women's sizes.
If your measurements fall between two sizes, choose the smaller size for a tighter fit or the larger size for a looser fit.
