"While a lot of other boots sport flashy knickknacks that don’t have much substance, the new Sidi Vortice’s features have all been designed with rider protection in mind, with input from orthopedic doctors as well as racers. It was difficult to imagine Sidi improving upon the Vertigo Corsa, but they’ve managed to do just that with the new Vortice."
