Follow these steps to discover your ideal size:

1. You need a flat surface, a sheet of paper, a pen and a ruler.

2. Put your foot on the paper with all your weight on that foot, if someone can help you better.

3. Trace the outline of your foot with the pen or marker in a completely vertical position.

4. Now, measure from the center of your heel to the top of your foot


Your size is measured in centimeters, that is, if your foot measures between 23.4cm and 24.3cm, your size would be rounded up to 24. If your foot is wide, in that case you should order size 24.5 since 24 and 24.5 measure exactly what same length (24cm) only changes the width by increasing 5 millimeters.

Use the size chart, if you still have doubts contact us and we will gladly advise you.
