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.
