Portable Flat Shoes Size S (22.5-23cm) With ribbon I bought these intending to use them, but I haven't had many opportunities, so I'm selling them. They fold in half for compact storage, making them easy to use. They're convenient to bring to school events like class observations, parent-teacher conferences, and board meetings, so you don't have to use the shared slippers. Perfect for entrance ceremonies, kindergarten entrance ceremonies, graduation ceremonies, elementary school graduation ceremonies, indoor shoes, and slippers. naks
