100 mm Low boots - Calf leather - Black - Women Size: 36.5 Combining simple elegance with clean lines, the So Kate Booty has become a true icon of Christian’s design repertoire. Curved lines gently encase the foot, secreted by a zip closure, and plunge down to a pronounced vamp ending in a winklepicker point. The sophisticated upper perches atop a wearable 100-mm stiletto heel that elongates the leg. This season’s iteration comes in a vampish black calfskin leather, lined with signature red. The unmistakable pop of red graces the bottom of every Christian Louboutin creation. It's more than a sole, it's a signature.
