Ballet flats made from rain shoe material. Okay for rainy days. They are size S, but they were a little tight on me, and I usually wear 22.5-23cm shoes, so I think they would fit someone around 22cm perfectly. I wore them outdoors about twice. They are soft and have a slightly deeper instep, making them easy to walk in, and I loved the subtle ribbon accent ⭐︎ ● Official product description These ballerina-type rain shoes are perfect for commuting and everyday use. They are easy to match with outfits in light rain or during the rainy season, and the design is suitable for all seasons. The soft rubber flat type also prevents stuffiness. The deep foot opening and cushioning also make them comfortable to wear, making them a recommended pair. *Due to the nature of products using natural rubber materials, the rubber components may appear white due to external factors such as ultraviolet rays, dryness, and being left wet. Please avoid using cleaners and clean them by wiping them with a dry cloth. Thank you for looking.
