Rihanna knows the power of a sassy shoe and her latest footwear obsession is anything but straight-laced. She is so smitten with her DSquared2 ankle-wrap sandals that she's got them in black and baby blue (also trending, FYI). Meanwhile Karrueche Tran and Aussie model Jesinta Campbell are bringing their super-strong strappy shoe game, too. In movie terms this shoe is Gladiator meets 50 Shades. Think of the sandals as the sassier, sexier, summery sister to those lace-up pointy super-flats that the likes of Alexa Chung have been rocking all winter. Whether you're wearing jeans, denim cut-offs or a slinky evening dress, this fancy footwear will inject guaranteed va-va-voom to any look. Here's why you need these shoes in your life.
