I purchased these online as a general M size (23.5-24 cm). When I, who am 23.5 cm, wear them, there's a little extra room around the heel. Size: 37 (M size 23.5cm-24cm) Heel height: Approximately 5cm I've worn them about 3 times, and the soles are still in good condition with little wear. I'm selling them because I've started wearing sneakers more often and don't have the opportunity to use these. Please understand that these are used items stored at home before purchasing. Please also read my profile. Thank you for looking! Wedding, entrance ceremony, kindergarten entrance ceremony, graduation ceremony, Shichi-Go-San (Children's Day), office casual
