Size S: 23 cm/ EU 36/37

I'm the second owner, bought them around 2018, worn twice since then. Most of the time they were stored in a box.

When I got them, the strobel was already wrinkled.  I have no idea how often and intensive they have been worn by the previous owner.  I never managed to get these wrinkles out, that why they are now crumbling. Except for that the shoes can be worn normally.
