Sizing Tip for Growing Feet
When buying shoes for children, leave about 1 cm of room beyond the longest toe to allow for growth. Avoid buying shoes more than one size too large, as this can affect balance and comfort. Re-measure every few months to keep up with growth spurts.
Frequently Asked Questions
What is a US children's size 10C in EU?
A US children's shoe size 10C corresponds to EU 27. The 'C' suffix indicates a children's size (toddler through young child). As children grow, US sizing switches to youth sizes with a 'Y' suffix, starting at 1Y which equals EU 32.
When do kids switch from children's to youth shoe sizes?
In the US system, children's sizes run from 1C to 13C (approximately ages 0 to 6), then switch to youth sizes starting at 1Y (approximately ages 6 to 12). After youth size 6Y, children typically move into adult sizing. The EU system uses continuous numbering and does not have this split.
How often should I measure my child's feet?
Children's feet grow rapidly, especially in the first few years. It is recommended to measure every 2 to 3 months for toddlers, and every 4 to 6 months for older children. Always measure both feet, as they may differ in size, and use the larger foot for fitting.
How do I measure my child's foot for shoe size?
Have your child stand on a piece of paper with their heel against a wall. Mark the tip of the longest toe, then measure the distance from the wall to the mark in centimetres. Compare this measurement to the foot length column in our size chart for the most accurate fit.
