I bought these on Rakuten for around 4000 yen and used them when performing on stage at the Mirror Ya. I haven't used them many times, but I think I wore them once at an outdoor event, so the soles are somewhat dirty. I've been wiping them with wet wipes because they seem like they'd be ruined if they got wet. I wore the heel caps to prevent scratches on the stage. Size 37. Heel height is about 5.5 cm. They should fit someone who usually wears a size 23 or 23.5 cm. I'm not good at dancing in heels, but these were easy to dance in. Suitable for Latin dance and social dance.
