I saw these shoes on the Banana Republic website, but they don't sell them nor does Piperlime. I have spent my morning searching for them - I've looked at Nordstroms, Bloomingdales, Saks, Neiman's, Barneys, Zappos and Shopbop, but am having no luck.
These are the Chloe Susan Studded Ankle boot, from f/w 08 and sold out... best bet would be ebay, otherwise they were widely done by many of the cheaper shoe brands ie. Steve Madden etc. Jeffrey Campbell also does a decent 'copy' of them, if you're looking for a cheaper alternative.
And for some reason the link to the 'fashionista' isn't working for me... so I can't help there, sorry.
