wich one? the pointy pumps are not from diagi, they´re from dimarni. some of the black boots are diagi.
i´ve never found any in
www apart from this man with the flickr account called "extraitaly" he is also a ebay (ebay.it) seller called "rubycloe" just send him a picture from the flickr-pages of the shoe, you desire and he´ll order it for you...(pumps 300 euro and up)
hope this will help you.
the quality of the shoes is high and i´ve heared from some guys, that you can trust rubycloe...never heared of any problems...
