Shoe size calculator
Calculate the correct shoe size for your child
Enter the foot length (from 108 mm)
How to correctly measure foot length:
- Take off your child's shoes and let them take a few steps in socks. For the best results measure in the afternoon or evening, as feet can swell slightly during the day.
- Mark the foot length with a pencil in front of the longest toe. Make sure the pencil is always held perpendicular (at a right angle) to the paper, otherwise the measurement may be distorted. Then repeat the process with the other foot.
- Measure the distance from the bottom edge of the sheet (the side against the wall) to the drawn line and enter the result in millimetres into the Superfit size calculator.
If the feet have different lengths, use the longer foot as reference.
