Baby and Kids Shoe Size Chart
🌟 Mom Tip: If you’re between sizes, we recommend sizing up to give little feet room to grow.
Internal Size is the space inside the shoe. Your child’s foot should be 0.6–1 cm shorter than the internal length for the best fit.
For example: 13 cm internal length = Best for a 12–12.5 cm foot.
Please use this guide to find the best size for your baby's comfort and growth.
🔹 Note: Our primary sizing uses US sizes.
EU & UK sizes are for reference only.
Inches (in) and centimeters (cm) refer to the internal shoe length.
