I actually have a very similar pair of Manolos - they're d'orsays with the same heel height but with a slightly different buckle-thing in front. My husband got them for me for my birthday last year (isn't he the coolest!). Honestly, they're the most comfortable shoes I own. If I wasn't scared of ruining them, I'd wear them everyday. And they're such a classic style - you could wear them forever.
Ok, maybe i'm just sleep deprived, but i don't like them - just not special enough to be a blahnik - the line looks weird or something. but maybe they're fabulous on.
