The Loubishark Donna sneaker focuses on a blend of materials to reveal the full extent of Maison Christian Louboutin's creative savoir-faire. This daring model sits on a red rubber sole reminiscent of shark's teeth. With its spiky trim, its iridescent silver calfskin upper is finished with a medley of topstitched effects. A neoprene heel insert is embellished with the brand's signature metallic spikes.
