These are platform sneakers from dear.ful, a budget-friendly brand produced by Aya, purchased at Shimamura. The color is blue gray (medium blue). The size is LL, which is 24.5cm to 25cm, so I've listed it as 24.5cm. I only tried them on, and they are new with tags. Please refrain from purchasing if you are sensitive to items that have been stored at home. Feel free to ask any questions or negotiate the price!
