To find which Sidi size you are, follow the instructions below:
- Put a piece of paper on the floor against the wall.
- Put your foot on top of the paper with your heel firmly against the wall.
- Make a mark on the paper at the end of your big toe.
- Measure from the end of the paper to the line you have drawn.
If you have measured correctly, you will have an accurate foot length in millimeters. Repeating the steps a few times will allow you to be sure you have measured correctly.
The length in millimeters on the size chart refers to the size of the last used, so if your foot length falls between sizes, be sure to size up rather than down.
