These are collaboration sandals from Adidas and Gucci. I purchased them at the Gucci outlet in Nagashima. I don't remember the exact number of times I wore them, but I think it was around 2-4 times. I didn't wear them much, so there isn't any noticeable dirt or stains except on the soles. I am not including the accompanying drawstring bag as I am currently using it. Regarding the receipt, I will cut off the portion with my personal information before shipping. As for the size, I usually wear 27cm sneakers, and this size fit me perfectly. The listed size is 26cm, but the sandals are made large, so I think they will fit someone who wears 27cm as well.
