Size guideTo measure, please make sure you have a ruler, paper, and a pen/pencil. Please note our shoes have unique construction and therefore different measurements for shoesizes. It is therefore advices to always check the sizeguide before placing an order. For kids shoes, please allow 1cm extra room for growth, 1.5cm for winter styles.
Place paper on ground against a wall and place the foot with heel against the wall. Avoid a wall with skirting, as this might give wrong measurements.
Trace against the toes with the pen and measure the length from the wall to the traced line.
