Love it!
Size: 10 Toddler, Color: Snow White - Red
My 3 year old absolutely loves these shoes! True to size, I bought a little bit beigger so they last to summer. She can put them off and on by herself. They are very light. She wears them on sucks and sometimes without. They smell good: )
Design is perfect. She can run in them easily. Highlighly recommend even though price is expensive. But I don't plan to buy any extra shoes for summer but water and sneakers, so it is OK.
