These are room shoes from MUJI. I bought them about 3 years ago for my child's graduation ceremony. I used them once for the ceremony, but the size didn't quite fit, so I've kept them at home since then. They are navy blue, ballet flat style, and have an elegant shape. They would be good for graduation ceremonies, but they are also convenient for school events where indoor shoes are required. They have elastic strings that can be used to tie the left and right shoes together, as shown in photo 8. - Brand: MUJI - Model Number: G9SD610 - Size: L size, 25cm Thank you for looking.
