Please note, SIDI shoes are a narrow fit. We recommend going up a size from your normal shoe. Follow the procedure below to ensure that you choose the right size in your new SiDi shoe.
MEASURE YOUR FOOT BY FOLLOWING THESE STEPS: :
- Put a sheet of paper on the floor with the short side against the wall.
- Put the sole of your bare foot on it with the heel pressing against the wall
- Mark the point in front of the tip of your longest toe on the sheet of paper.
- Measure the distance between the margin of the sheet of paper where you placed your heel and the point where you made the mark. Always round up the measurement to the next millimetre.
You may find that your right and left foot are different lengths. Always measure both of them and use the longest measurement as your reference. If you are undecided between two sizes after consulting the table, we recommend that you opt for the larger size.

How to measure for your shoe size at home
- Take a piece of blank paper and put it on the floor next to a wall. Place your foot on top and put the heel against the wall. Mark where your longest toe is and the outer edge of your heel.
- Measure the distance between the two points.
- Measure both feet. Use the measurement for the larger foot when choosing your running shoe.
