The size is 18cm. - Brand: YONEX - Model Name: POWER CUSHION JR 19 - Color: White/Blue - Material: Synthetic Leather - Features: Velcro straps Thank you for viewing. I used these shoes once a week for 3 months while attending an indoor tennis class. As shown in photo 3, there is some slight soiling, but I don't think they feel heavily used. Please understand that there may be individual differences, and I will sell these to someone who understands that they are used items.
