Size Guide

Size Guide

Every child grows differently. We recommend measuring your little one and using this guide as a reference — sizing may vary between styles.

Sizes 0–24 months. Measure height and chest for the best fit.

Shoes

Measure your child's foot from heel to longest toe while standing on a flat surface. Use foot length as your primary guide — if between sizes, choose the larger size for growing room.
