We're going to have to ask you to take a long hard look at this particular ugly shoe, because it's not immediately obvious which bit fits where, and you need to fully get your head around it to appreciate its true vileness. 

At first glance, there appears to be an impossible Escher-like illusion going on, but what you're actually looking at is a 'shoe without a heel' that has had a sort of redundant micro-heel added at the back: that heel simply floats in mid air. Eew!

It will come as no major surprise if there's dissent on this one: after all, there are some fairly on-trend aspects to this peculiar piece of footwear engineering from Nina Ricci: the oil-slick coating is very now, as is the lacing and the front-loaded weighting. But what the actual heck is going on with that floating heel? It's just unnecessary.

The moral of this story is: if you're going to make shoes without heels, for goodness sake don't add a heel. The clue's in the name, Nina!
