Just measured
EU 26 in Igor · EU 25.5 in Naturino
Same feet, different last. That's why brand calibration matters.
The tiny-shoe problem
Sizing kids' shoes online has always been a bit of a gamble.
Feet grow overnight. Every brand's last runs a little different. Printable charts curl at the edges, rulers slide, toddlers wiggle. Just Shoes for Kids was founded because shoe shopping for little ones was harder than it needed to be. Size Wise is the next step in that promise: a fit you can trust before you ever click add to cart.
