How to Measure for a Perfect Fit
To ensure the "Pristine Fit" for your child, we recommend the following concierge-approved method:
-
The Trace: Place your child’s foot flat on a piece of paper.
-
The Mark: Draw a line at the longest toe and the back of the heel.
-
The Measure: Measure the distance in centimeters.
-
The Allowance: For closed shoes, add 0.5 cm to 1 cm for growth and movement.
A "Gallerie" Note on Sizing
Please note that luxury designer brands (such as Dior, Gucci, or Burberry) may vary slightly in their cut. If your child is between sizes, we recommend selecting the larger size to ensure comfort and longevity of the acquisition.
