Platform sole Heel: 9 cm Platform: 2.5 cm The insole has cushioning and is very easy to walk in. The opening is also soft, so your shins won't hurt even if you squat or bend your ankles. Although I cut off the tag, it's new and unused. It only says size M, but I think it's about 23-23.5 cm. It was a little too big for me, who wears 22.5 cm.
