I accidentally bought this. It's size L. The model's size was listed as 23.5cm. Instant purchase OK Official description below: Adult-healthy mesh sandals ◆FABRIC Sandals that brighten up your feet with a thong design and sheer mesh material. The sheer material adds a sense of抜け感 (nukegankan - a feeling of openness/breathability) and lightness. The flat sole is easy to wear even for those who don't like heels, and it's also easy to walk in. Available in two colors: classic and easy-to-match BLACK and easy-to-blend BEIGE. *This is a select product, so the product logo is not VACANCY. Thank you for your understanding. ◆STYLE These shoes can be worn daily with skirts or pants. They are also recommended as an accent for patterned pants and dresses! ・・・・・・・・・・・・・・・・・・・・ Sheerness: Mesh available Lining: Yes Elasticity: None Glossiness: None Heel: None ・・・・・・・・・・・・・・・・・・・・
