Rebeca Sanver "cage" shoes

I wanted to show you some photos of these shoes I found the other day, that I really really like. They remind me of the ones YSL was doing a few seasons ago.

These are OLD...but you couldn't believe how solid they feel and how well they're made...I don't know what this material is..it's polished and shiny, it feels like hard resin. God I love shoes. They look like Givenchy.
