HEALTHY SHOES FOR KIDS - Approved by APMA (American Podiatric Medical Association) and developed with doctors, our baby & toddler shoes come with a wide, foot-shaped toe box with lots of breathing room (no squished toes!) for healthy development, and flexible, zero-drop soles for natural movement. SIZING - Ten Little shoes may run smaller than mass brands due to our proprietary shape designed for healthy development. You may need a larger size!

Each pair includes removable character insoles to help kids learn left from right while also helping parents confirm size. ENHANCED TRACTION - Our Splash Sandals are designed with non-skid, high traction soles and a textured footbed to keep slippery feet in place and give your child the confidence to splash and play safely.
