Manolo's Exclusives?

I don't know about these 'EXCLUSIVE' Manolo Blahnik sandals for Neiman Marcus.. I am almost 80% sure that I've seen something exactly like them from Stuart Weitzman about a year ago and I'm almost certain that these were the 'Stuart Weitzman' sandal my cousin wore on her wedding day. Okay fine, there are many similar looking sandals around but I guess I expected more from Manolo Blahnik - especially since Sex In The City dedicatedly featured Blahniks in most of its episodes. But I'm not sure who's to be blamed - Neiman Marcus for choosing this shoe as their 'exclusive' or Manolo Blahnik for the design?
