Look sharp!

In an industry as trend-focused as fashion, it’s rare that a shoe manages to stick around for several seasons — let alone a decade.

But this month marks the 10th anniversary of Casadei’s “Blade” heel, a favorite of celebrities ranging from pop queens like Madonna and Taylor Swift to A-list actresses including Angelina Jolie and Zendaya.

And these aren’t your standard-issue stilettos; true to its name, the “Blade” shoe is set on a slender, razor-sharp steel spike. In a 2014 interview with The Independent, creative director Cesare Casadei referred to the invention as his “obsession,” revealing that it took more than five months to perfect the edgy design.

And it wasn’t long until stars became obsessed, too; Kim Kardashian called her hot pink pair “perfect” way back in 2012, while Victoria Beckham’s been snapped wearing them in at least half a dozen different colors.
