I purchased these online in December 2025. They were a bit tight for my feet, which are 25cm, high-arched, and wide, so I am selling them. I tried them on once indoors and put them back in the bag immediately, so I don't think there are any stains, but please understand that they have been stored at home. Soft fabric and synthetic sole slippers, designed for easy portability. - Color: Black - Size: L
