Thank you for viewing. [Product Name] NIKE REACT X INFINITY RUN 4 [Color] Black Please check the images. [Size] 25.5cm [Condition] I used them for running for about a month. They didn't suit me, so I'm selling them. I didn't run much. Please check the soles in the photos. Also, I washed them with a scrub brush the other day, so I think most of the dirt has been removed. The original Nike insoles are not included; instead, STEP original insoles "Functional Fit Running Model Red" are inserted. If you have any questions or concerns, please feel free to ask. As this is a used item, please refrain from purchasing if you are sensitive about such things. Thank you.
