These are Adidas sneakers with Velcro straps, making them easy to put on and take off. The size is 21.5cm. There is some wear and tear on the heels (please see photos 7, 8, and 9). Would these be suitable as a second pair for rainy days? *I am selling these because my child has outgrown them. Please understand that these are used items before purchasing. Thank you for looking.
