Thank you for viewing. This is the Adidas Adizero Boston 12. Size: 23.5cm I ran about 7km in these after purchasing them. I bought the 23.5cm size because the 24.0cm size was too big, but they didn't fit my feet, so I'm selling them. There is no noticeable wear on the soles, and I think they are in relatively good condition, but they are still used, so please consider purchasing only if you understand this. Thank you.
