Number of times worn: Less than 5 times. Each time, they didn't want to wear them much, and only wore them for a short time. Condition: There is some soiling from wear, but the wear on the soles doesn't seem to be significant. Size: 14cm. NIKE kids' sizes tend to run large. I think they would be perfect for a child who wears a size around 15-15.5cm. Product number: CJ3818-002
