Grumplets Size Guide
Grumplets shoes use European sizing. US and UK conversions are approximate; fit varies by brand and style.
Measure both feet while your child is standing, from heel to longest toe, and use the longer measurement. Foot lengths below are approximate guidance, not internal shoe measurements. Age ranges are rough estimates only—choose by measurement and fit, rather than age.

All age ranges are estimates and can vary considerably between children. Y = US youth sizes. This chart does not indicate stock availability.
Fit notes
Grumplets styles may have a wider, more foot-shaped toe box than conventional children’s shoes. A roomier look through the toes does not, by itself, mean the shoe is too large. Matching size labels does not guarantee identical fit between Grumplets and Tip Toey Joey.
For help choosing a size, email customer@shopgrumplets.com with your child’s foot measurement and the style you’re considering.
