Naturino Size 26 According to the official size chart, it's 17cm, but I felt it was a bit small, so I've listed it as 16.5cm. I purchased this item used once, and I also wore it once for an outing. The Velcro makes it easy for children to put on and take off themselves, and the arch-shaped cushion supports the instep, making it comfortable for them to walk. Thank you for looking. 【Naturino】 A children's shoe brand produced by the Italian company "Falc Spa," established in 1974. It has been a leader in the industry since its establishment. Based on the ergonomic "Sand Effect System" theory, which originated from the idea that sand perfectly molds to the shape of the foot, they developed the Sand Effect sole, which is a major feature. The insole provides ideal support for children's feet. They design shoes in collaboration with pediatricians, and the shoes are soft, flexible, and allow for natural foot growth without unnecessary constriction.
