How does a thousand-dollar shoe have a wait list about a mile long? Probably because of its intricate, lattice-like detailing and that heel. And while its far cheaper cousin, Topshop's Lattice Caged Sandal, doesn't exactly have that incredible cage heel, we're still in love with the black latticework. Yep, leave it to those crafty Brits (is it April 2 yet?) to come up with yet another enviable high street version of our fave runway look. Pair with all of your summer dresses to add instant attitude to anything you wear this season, and we bet by the time August rolls around, only a handful of the YSL hopefuls will have nabbed their pair.
