The inner sole of the shoes is 21cm. They fit perfectly when my daughter's bare foot measured approximately 20-20.5cm. They were only used once for a piano recital and are in very good condition. Color: Silver The sparkling beads are very cute♡ They have a strap, making them easy to put on and comfortable to walk in. Please understand that these are imported products before purchasing.
