Christian Louboutin Vieira sneaker in grey suede with silver spike studs across the toe cap and a white rubber sole with the signature red underside. Louboutin introduced the spiked toe on sneakers as a way to carry the house’s rebellious DNA into a more casual silhouette — the contrast between the lace-up sneaker construction and the hardware is exactly the point. Grey suede keeps it understated from a distance, until you look down.
