Sienna Miller’s Sculptural IRO Heels Proved Architectural Shoes Don’t Need Theatrics

At the Just Like a Woman special screening in New York City on June 5, 2013, Sienna Miller delivered a reminder that footwear—not theatrics—often defines the sharpest red-carpet moments.

Her black satin pumps appeared restrained from the front, but a side view revealed a dramatically sculpted fin-like heel that transformed the shoes into the focal point of the look.

While Casadei is widely associated with razor-sharp silhouettes like its iconic blade heels, Miller’s choice proved that striking heel architecture isn’t limited to one house. The unexpected profile of her pumps turned a classic black shoe into a conversation-starting design moment—one that still feels bold, directional, and distinctly modern years later.

They look like ordinary, boring black satin pumps when viewed from the front:

But check them out from the side. The sculptural heels delivered their impact without theatrics—proof that strong design speaks for itself.

For the screening at the Crosby Street Hotel, the British actress opted for a minimalist approach, pairing her look with IRO’s “Denka” pumps, whose architectural heel added edge without overwhelming the outfit.

Miller wore a Burberry Prorsum little black dress, letting the silhouette—and the shoes—take center stage. She skipped jewelry entirely, keeping the focus on proportion and line, and finished the look with fresh, dewy makeup: softly defined eyes with black mascara and liner, a subtle pearlescent glow on the cheeks, and a nude lip. Her blonde hair was pulled back into a ponytail, with her signature fringe skimming her eyes for an effortless finish.

Around 2013–2014, the IRO Denka pumps became a quiet cult favorite among fashion insiders, perfectly capturing the brand’s signature “Parisian rocker” aesthetic. Founded by brothers Laurent and Arik Bitton, IRO was best known at the time for its leather jackets—but styles like the Denka signaled the label’s growing influence in footwear as well.

IRO clothing and shoes are available at Farfetch and Shopbop, though the Denka pumps themselves are no longer in regular production.
