This is the Hyperdunk 2017 TB. The size is 27.5 cm. I only used it once after purchasing it new, in a casual game with adults. The grip and cushioning are both excellent, and it's a very popular shoe. Personally, I think it's the best shoe I've ever had. The price is set due to its high rarity. Please consider only if you understand. I didn't keep the box and tags, so I will pack and ship it in a different box. Please ask any questions in the comments section.
