These are Reebok sneakers. The size is 27.5cm, but they are made to fit loosely, so they might fit someone who wears 28cm. I usually wear 28cm, and the length and width were fine, but the top of my foot felt a bit tight, and I felt a little uncomfortable when walking. If you tighten the laces, I think they would be fine for someone who wears 27.5cm. There are no noticeable stains or scratches, but they are used items, so please understand. Final price reduction.
