This is the Rondinella product from the store called Arca. The size is equivalent to 15.5 cm in Japan. These are cool black shoes designed with your child's feet in mind, providing support up to the ankles. Wearing shoes with arch support and a firm heel from a young age, even before they can walk, will help them grow into someone who loves to walk and doesn't get tired easily. You can build good feet even before they can walk, just by wearing good shoes. The front tape allows for a snug fit. They are clean because they were only worn a little inside the house. Please feel free to ask any questions you may have.
