YONEX 23.5cm power cushion short boots. I think these would also be suitable for someone who wears 23cm. I bought these about two years ago because they looked easy to wear, but I have bunions and usually wear 3EEE, so I ended up not being able to use them. These are best for people with regular-sized feet. I remember the purchase price was a little over 10,000 yen. Returns are not accepted, so please consider carefully.
