Size guide

Measure the foot and match insole length (IN / CM). We sell mainly to the US — sizes below show USA first, plus UK, EU, IN, CM, and approximate age. Ages are a guide only — measuring is more accurate.

Tip: Kids’ feet grow fast. If you’re between sizes, choose the larger one so the shoe isn’t too small.

IN / CM is insole length. Age is approximate. UK / EU are approximate conversions.

How to measure

Have your child stand with the heel against a wall.
Mark the tip of the longest toe.
Measure heel-to-mark in centimetres.
Match that length to the IN or CM column (or size up if between sizes).
