◾︎ I wore these on stage only once for a rhythmics recital. ◾︎ I purchased these online, and the size isn't listed, but I think they can be worn up to 12cm. (See photo 5) ◾︎ The entire shoe, including the sole, is made of soft fabric, so I think even small children can wear them without discomfort ⭐︎ (I think they can also be used as indoor shoes.) ◾︎ I will fold the heel part for shipping. Please understand.
