Sentaro Getas I bought these about a year ago. I wore them only once for about 15 minutes. I was told they are 23.5cm but a bit large. (Apparently, men can wear them too) I bought them without knowing much about them. They have a unique shape, but the soles are flat and have thick cushioning, making them easy to wear. For more details, please inquire about Sentaro Getas. They cost 15,000 yen. The thong is made of good fabric. The color is indigo-like, either space or the earth?
