These are Asics Metaspeed Sky running shoes. Size 26cm. I used them for the actual Ekiden (relay marathon) race. I used them for a 5km road workout and a 10km Ekiden race, for a total of 15km. The shoes have been washed, so I think the dirt is minimal. There are no tears or peeling, and the outsole is slightly worn, but I think they are in reasonably good condition. *Please ask any questions in the comments.
