These are Nike Flex Runner 3 shoes. My child's feet suddenly grew, and they outgrew these without wearing them, so I'm selling them. The size is 17.5cm. They're easy to put on and take off, so my child likes this series and wears them. Perhaps the lack of shoelaces was a good thing, as they don't come undone. Lightweight and easy-to-wear slip-on blue kids' shoes. I plan to ship them without the box due to shipping costs. - Brand: Nike - Color: Blue - Style: Slip-on - Features: Lightweight design - Occasion: Everyday wear - Tags: New - Sole: Rubber sole Thank you for looking.
