The soles have been reinforced. Size is 36. I usually wear 23-23.5 cm. 8cm heel. I think I've worn them about 10 times. I like them, but I'm selling them because my style has changed. There are minor scratches on the heels, etc. Please refrain from purchasing if you are very concerned about details. *Returns are not accepted after purchase to prevent product substitution.
