On Cloud sneakers. Size: 23cm Color: White Purchase date: About a year ago *No box I bought these here about a year ago, but the size didn't fit, so I only tried them on and stored them. As shown in the images, there is noticeable yellowing and staining, which was present from the time of purchase. I have not done any home cleaning, so it is unknown whether the stains will come out. They should be fine to wear.
