Thank you very much for viewing. I purchased this one year ago. It is new and unused. Size: 27.5cm Product Overview: This is a perfect pair for short-distance running, going back to the origins of running shoes. The single-layer mesh lightweight upper enhances flexibility, providing a barefoot-like fit. By reducing the foam in the midsole, you can sprint immediately.
