Be sure of your size! This size guide will help you find the right shoes for your feet.
Place your feet on a sheet of paper and trace, with a pencil held, their contours. In this way you will obtain, for each foot, the maximum length and the greatest width.
Measure the length (toe-heel) and width (side line) of each of your feet in millimeters with a ruler.
