Good condition, no box.
These are out of production!

100% leather upper with Lucite heels.
There is a hidden platform, so the heel rise is relatively flat (similar to Moi Meme Moitie platforms).
The heels have a smoky black and grey ombre style and are blocky for balance.
The inner part of the shoe is painted with leather paint and has been rubbed away a bit on the sides.
It has a padded ankle cuff which runs a little narrow. It closes with Velcro.
It has cone spike studs on the cuffs and up the back.
It is missing a few studs which is common with this shoe.
Some of the studs on the back of the shoe feel a little loose.
You can easily replace the studs or paint over them (or add some other decoration).
It's not super noticeable that they're missing since they're lower on the shoe.
Otherwise, there are no scuffs or marks to the outside of the shoe and the leather is soft and supple.

These run narrow, so I would say narrow to medium width foot for best fit.
Because they are leather, it is possible to stretch them.

They run closer in size to street shoe or sneaker sizing, maybe one half size larger at most.
I have seen reviews online saying they run either small or a whole size larger.
I think you can go down half a size, but they can't go a full size larger.

Insole: 25cm long (10 inches)
Width: 8cm wide (3 inches)

They're marked 8US, so 38.5EU, 6UK, or 25JP (or size L/LL).
I think you can fit 7.5-8.5US, 38-39EU, 5.5-6.5UK, 24.5-25JP depending on the types of socks you wear and how wide your foot is.
I would measure a shoe you already own with a similar heel height if you're not sure.
