I spotted these in my Nordstrom email and had to find out what they were.
Duh. They're Lanvin. Maybe the giant 'Lanvin' there at the bottom would have given that away.
They're not for sale (yet?) on Nordstrom's site, but I did find them in brown (which doesn't look anywhere nearly as cool) at Luisa Via Roma.
These are the kind of shoes I picture as editorial centrepieces more than actually to be worn. Which is why I feel like I can admire them and not at all begrudge their $1600 price tag.
