Pro tips from our fit experts
- Measure feet in the afternoon when they're slightly larger
- Always measure both feet and use the larger measurement
- Leave about 0.5-1cm of growing room beyond the longest toe
- Check the fit every 2-3 months as children's feet grow quickly
- If between sizes, we recommend sizing up for growing room
