I used these as first shoes. I bought them new and wore them for about two and a half months. They are 12cm and the color is smoke gray x white. I washed them at home. There are a few scuffs on the toes of both shoes (marked with a red circle). They can still be worn, but please understand that they are used items before purchasing. The following is from the website: These are kids' shoes from the "FIRST" series, designed for babies in the first three months of walking. The shape of the toe is designed to curve upwards to prevent tripping and support smooth walking. Furthermore, the rounded edges of the entire sole reduce the chance of catching, which often happens when babies who are unsteady on their feet are walking. The inner material that touches the foot uses "Mediel," a low-irritation material that is highly absorbent, quick-drying, and gentle on the skin. The two-strap design makes it easy to adjust the fit, and the wide opening makes it easy to take them on and off. They come in a variety of colors that are easy to coordinate with clothing.
