I forgot the year I bought these, but I purchased them at Margaret Howell in Hankyu for 100,000 yen. Color: Black Size: 23.5 They don't have a zipper, but they are easy to put on. When I wore them, the soles felt a bit slippery, so I had them treated with anti-slip processing. I think I wore them about 4 or 5 times. I was keeping them carefully to give to my child, but it turns out the size doesn't fit, so I'm putting them up for sale. They are in very good condition, but I would like someone who understands this to use them. Thank you.
