SIDI size measurement procedure.
Measure your foot by following these steps to obtain the reference measurement.
1.Put a piece of paper on the floor and mark the following points.
2.Mark the point in front of the tip of your longest toe and then mark the heel point for both left and right
3.Measure the distance between the heel mark and the toe mark. Record the cm/mm measurement and compare to the size guide chart for the suggested size. Use the size of the larger foot, most people will have slight difference between the left and right foot.
