Candy Floss is for the kid who wants something that feels a little special and for the parent who isn't prepared to compromise on what that kids' shoe is actually doing for their child's feet.
1. SuperGrooves sole expands across 3 sizes, up to 18mm of real growth absorbed into one pair. It's a sole that physically adjusts as the foot does. The wide toe box is shaped around Natural Foot Shape research, meaning it matches how a small foot actually looks, broad at the front, not pinched into a narrower adult silhouette. Zero-drop heel to toe because that's what lets growing bones and posture develop the way they should.
2. SquishyFoam cushions without over-cushioning. The ground feel stays, which is exactly what developing feet need. Infiknit upper is soft, stretches without resistance in every direction, and breathes without needing to be told to. No dampness, no stiffness.
3. Slip-on with elastic flex. No laces, no argument. Kids manage it themselves and mornings stay manageable.
4. Reinforced where it matters, at the toe and heel, for the play that doesn't slow down for shoes. EU 20 to 37.
