Zendaya and Law Roach have sent demand for this stiletto heel soaring

While it may appear to be a simple, ubiquitous shape, crafting a stiletto that makes its wearer feel incredible is actually a fine art – one that many have tried to master, but no-one has succeeded quite like Louboutin. The So Kate’s stiletto reaches a perilous 120mm and plunges into an ultra-low vamp, creating the ultimate leg-lengthening illusion. The sides are cut away to expose the foot, while the heel is as thin and as sharp as a nail. In short, they’re astonishingly flattering. As Louboutin himself says, “Kate is a sharp style, simple, and very complex at the same time. If the line is not very perfect, you don’t have any embellishment to hide it.”

And it’s not just the red-carpet where you might glance a flash of that iconic red sole: the shoe has made it into wardrobes the world over, called on for evenings out and grand events whatever the whims of the seasonal trend cycle are saying. “Net-a-Porter first invested in the So Kate 120 for AW13 with iterations such as the So Kate Booty 85 and So Kate 70 leather slingback pumps remaining incredibly popular with our customers,” says Libby Page, market director at Net-a-Porter. Proving its unwavering popularity, the luxury fashion etailer has sold over 12,000 pairs of the So Kate since launch – and searches for the shoe have risen 25 per cent in the past six months (call it the Zendaya effect).

If you’re in search of the ultimate, wear-with-everything stiletto heel, that search will end at So Kate. In glossy black patent leather, it will lend a sultry spin to timeless tailoring, while the glossed pink iteration is perfect for wearing to more formal events. Heading to a wedding? There’s a So Kate to match every dress, be it a thigh-grazing mini or floral-print maxi (although it should go without saying, you won’t be equipped for grassy terrain). And if you’re the bride herself? Kate comes in pristine white leather, too.
