Size Guide
Children's shoe sizing is not perfectly standardized. Use this children's shoe size guide to compare European sizing with the brand-specific guidance for Grumplets, Tip Toey Joey and Lazare. A size in one brand can fit a little differently in another, so we recommend measuring your child's feet and checking the guide for the specific shoe you are considering rather than relying on age alone.

How to measure children's feet for shoes
- Measure both feet while your child is standing.
- Measure from the back of the heel to the tip of the longest toe.
- Use the larger measurement and compare it with the relevant brand guide.
- Check the product page for any style-specific fit notes.
Foot length is the best starting point for choosing a size. If your child falls between sizes, consider the shape and construction of the particular style rather than sizing up automatically.
A note on barefoot and wide toe box styles
Barefoot and barefoot-inspired children's shoes may look roomier through the toe box than conventional shoes. That extra space is intentional. Choose by foot length first, then use the fit notes for the individual style.
Still between sizes?
Growing room is useful; swimming room is not. If you are unsure, email customer@shopgrumplets.com and include the style you are considering and your child's foot measurement.
