Purchased from Amazon in March 2025. I am selling these as I bought the 23.0cm-25.0cm size, but they were a little small for my feet (24.5cm). I have worn each of the three pairs once or twice, but there are no stains or tears. I will wash them at home before shipping. ◎Size 23.0cm-25.0cm ◎Material Polyester Polyurethane
