The size is 19cm. This is a used item. I really love them, but I'm selling them because my child has outgrown them! Power confirmed. Kids' sneakers featuring sparkling stones on the toes and wing designs on the sides! These are light-up flash sneakers that light up when you walk! The lights on the toe stones and wings flash with every step! Comes with an ON/OFF button, so no wasted battery! Rainbow colors are perfect for girls! Zipper closure makes them easy to put on and take off! Please check the images for the condition. I don't think this design is commonly seen in Japan, so please consider them if you're interested! As these are used items, please refrain from purchasing if you are concerned about minor details. *Please note: The light-up feature may stop working due to battery life. The batteries are not replaceable.
