Instant purchase ○ ⚫︎ GU 　Strap Ballet Sneakers　Size S　RED I am selling these because I used them once after purchasing them and then bought a size M. I usually wear 23cm Adidas sneakers, and the size S was too tight, making my toes feel cramped when I walked. ★ My feet are narrow, and other ballet shoes tend to slip off easily, but these are very easy to wear because they have a strap! ★ The material is generally soft, and the soles are fluffy and flexible, so it seems like there would be no problem walking for long periods of time! They are almost new, so please consider them!
