FAQs
Why do kids’ sizes vary so much?
Kids shoes differ by brand, age band, and whether the shoe is measured for growing room. Foot growth can also be rapid.
Should I size up for kids?
Many parents size up slightly for comfort and growth, but too much extra space can cause trips or rubbing. If possible, check the foot length (cm) method or brand guide.
