I purchased these, but they became too small before I could use them. I only tried them on once indoors. Please understand that there may be minor, inconspicuous marks from storage on the rubber soles, etc. To adjust the size for shipping, I may need to fold the heel slightly when packaging. I will use simple packaging, and I hope you understand. ^_^ #IndoorShoes #GymShoes #GymnasiumShoes #19cm
