When it comes to its designs, Diesel has never been one to think inside the box – and so, it should come as no surprise that the Italian label chose to collaborate with fellow boundary-breaker Melissa for its latest creation. Dubbed the Quantum Thong, this sandal features a futuristic allure, from the spiral-adorned sole, to the exaggerated thong strap, to the stacked heel. Rendered in Melissa's signature eco-friendly rubber, they're certain to make a lasting statement wherever you go.
