Black calfskin leather defines these pointed ankle boots by Mach Mach, embellished with eyelet studs and rhinestones down the lace-up sides. The textured metal details run from the cuff to the toe, creating an edgy geometric accent. A side zip closure provides practical entry, while the leather sole and slim heel support the architectural silhouette. Style them with tailored trousers or a slim midi skirt for evening impact.
