For hard and carpet courts. This is the latest model, released late this year. I used it only once, but I'm selling it because I ordered the wrong size. It was used indoors for a very short time, so there is no dirt or damage. - Brand: prince - Model number: DPS522-215 - Color: White/Green - Size: 26.5cm (4E) - Included: Outer box, spare laces (navy)
