office-alex.jpgZips have been a major fixture on footwear for the past few months, but only in these two cases have I seen the feature used in quite the same way. The zip holds the two sides of the shoe together, and can be adjusted for more or less 'toe cleavage'.

Office, quite sensibly, have opted for a closed-toe style, while Alexander McQueen still comes out on top for this cheeky skull zip fastening. But would you really want to pay £355 for these flimsy little flatties? If so, you can order online at Saks Fifth Avenue. The Office variant is available in the sale in a range of colours at twenty quid.
