The color is light gray x light blue! The size is 12.5 cm. I wore these in the fall/winter of 2025. Please check the photos for any stains. From the official website: We worked with the editorial department of Benesse Tamahiyo to create shoes that mothers would want. These shoes are designed for babies who are just starting to walk, for about three months. The shape of the toe is raised to prevent tripping, and the lightweight and flexible California construction supports smooth walking. Furthermore, by rounding the edges of the entire sole, we reduce the chance of catching, which can often happen when a baby is walking unsteadily. The inner material that touches the foot uses "Mediel," a material that is highly absorbent, quick-drying, and gentle on the skin. We also included a line to indicate when the shoes are outgrown and illustrations to help children recognize the left and right shoes. The two adjustable straps make it easy to adjust the fit, and the wide opening makes it easy to put on and take off. The upper is made of lightweight and soft microfiber artificial leather. Clear material is used for the ASICS stripes to express the pure image of the child.
