Purchased about 5 years ago. ⭐︎ Regarding maintenance: I had the soles and heels replaced at a repair shop and wore them about twice since. The rubber strap at the back was replaced once, but the color has deteriorated, so I recommend replacing it. Upon close inspection, I found one of the individual decorative pieces was missing. It's like a spot-the-difference puzzle. The satin is clean. Thank you. The sole and heel replacement cost over 5,000 yen, so I think this is a good deal.
