René Caovilla's Onda sandal is a sculptural black satin heel defined by its signature spiral strap wrapping the ankle in a graceful wavy pattern. Hand-applied crystals create a sophisticated play of light across the straps, complemented by a 10.5 cm stiletto heel. The iconic glitter-finished sole bears the golden Caovilla logo, a hallmark of Venetian craftsmanship. Perfect for evening wear, this design combines seductive elegance with architectural precision.
