Naito's Yubimata kappo, CoJOJO. Color: Navy Sole: Approximately 14.8cm Retail Price: 16,500 yen I used these a few times indoors, but I'm selling them because they didn't work out for me. These are not ordinary sandals; they are for training, and they have no heel. Please only purchase if you understand that these are used items. "Heel Revolution!"
