These are Crocs sandals with a boa lining. The color is navy. The size is J3, which was worn by someone around 21cm to 23cm. Bayaband Lined Clog I am selling these because they are too small. They are for winter, so they haven't been worn many times, but they are used items, so if you are particular about the quality or storage condition, please refrain from purchasing to avoid any problems.
